Calcium (Ca) Test measures the levels of calcium in blood. Calcium is essential for body processes including cell signaling, blood clotting, contraction of muscles, and functioning of nerves. It plays a crucial role in the formation and maintenance of healthy bones. Deficiency of calcium results in Osteoporosis, a disease in which the bones lose their density and become soft and fragile, causing them to fracture very easily.

About 99% of the total amount of calcium received by the body is bound as calcium complex in bones, and the remaining 1% lies in blood circulation. Of the amount of calcium circulating in the blood, about half remains bound to albumin protein or other ions and are metabolically inactive, while the remaining half remains free and metabolically active. Blood Calcium tests can be of two types: Total Calcium Test used to measure the total calcium concentration in blood including both the free and bound forms, and Ionized Calcium Test used to measure the concentration of only the metabolically active form.

Calcium levels in the blood are maintained within a very narrow range by a number of mechanisms. Deviation from the normal range of calcium concentration causes Hypocalcemia (low levels of calcium), or Hypercalcemia (excess of calcium). Both these conditions impact normal body processes in the short term and may give rise to other conditions in the long term.

A blood calcium test cannot be used to check for a lack of calcium in your diet or for osteoporosis (loss of calcium from bones) as the body can have normal calcium levels even in case of dietary deficiency of Calcium. The body can augment mild calcium deficiency by releasing the calcium stored in bones.

Vitamin B12 is a part of B complex of vitamins. Vitamin B12 is also called as Cobalamin. It is a water soluble vitamin. Vitamin B12 plays an important role in formation of normal red blood cells, repair of tissues, DNA synthesis and genetic material in cells. It is not produced in the body and has to be taken in diet. The diet sources include red meat, fish, milk, poultry, yoghurt, eggs, fortified cereals, breads and other grain products. It can also be taken in the form of Vitamin B12 tablets or multivitamin pills. The deficiency of Vitamin B12 results in macrocytic anemia (size of red blood cells larger than normal).

Megaloblastic anemia is a type of macrocytic anemia, in which large size red blood cells called as macrocytes are produced. These red blood cells are fewer in number. There is a decrease in white blood cell count and platelet count. Megaloblastic anemia occurs due to acquired deficiency of Vitamin B12. The reason can be an inadequate dietary intake of Vitamin B12 or any problem in the absorption of Vitamin B12 from the intestines.

In case of problem in the absorption of Vitamin B12 from intestines, it is known as Pernicious anemia. It occurs due to lack of intrinsic factor which is present in secretions of the stomach.

Vitamin B12 is also important for nerve health and is taken as a nutritional supplement for the treatment of nerve damage.

Vitamin B12 binds with intrinsic factor (protein secreted by cells in the stomach). After binding, a complex is formed which is absorbed by the small intestine. In case of any disease interfering in this process can cause weakening of absorption of Vitamin B12.   

The ESR test measures the rate at which red blood cells (erythrocytes) settle (sediment) at the bottom of a tube that contains a blood sample in one hour. The test result is expressed in millimeters per hour (mm/hr).

In the presence of inflammation, certain proteins mainly fibrinogen increase in blood. This high proportion of fibrinogen in the blood causes the red blood cells to form a stack (rouleaux formation) which settle quickly due to their high density.

The ESR test is a non-specific measure of inflammation. An ESR can be affected by conditions other than inflammation also. Although a high ESR can detect the presence of inflammation, it cannot provide any information regarding the cause and site of inflammation. Hence, an ESR test is done along with other tests.

Blood Stag is composed of blood cells suspended in blood plasma (yellowish-colored liquid). The blood cells include red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes), and platelets (also called thrombocytes).

Red blood cells (RBCs) are the most abundant blood cells. RBCs contain hemoglobin which helps in the transportation of oxygen to the tissues. RBC count is the measurement of the number of RBCs in a given volume of blood.

Packed Cell Volume (PCV) or Hematocrit (Hct) is the measurement of the blood volume occupied by RBCs. It is expressed in percentage.

White blood cells (WBCs) are key components of the immune system and thus protect the body from various infections and cancers. Total Leucocyte count (TLC) is the measurement of the total number of leukocytes (WBCs) in a given volume of blood.

There are five types of WBCs:

1. Neutrophils

2. Basophils

3. Eosinophils

4. Lymphocytes

5. Monocytes

Differential Leucocyte Count (DLC) determines the percentage of different types of WBCs.

Neutrophils, Basophils, and Eosinophils are called Granulocytes because of the presence of granules inside these cells.

Absolute count of different types of WBCs is the measurement of their absolute numbers in the given volume of blood.

Platelet count - Platelets (also called thrombocytes) are disc-shaped cell fragments without a nucleus that help in blood clotting. Platelet count is the measurement of the number of platelets in a given volume of blood.

Mean Platelet Volume (MPV) is a measurement of the average size of platelets.

PDW or platelet distribution width refers to the variation of platelet size distribution

Hemoglobin (Hb) -  Hemoglobin (Hb) is a protein found in red blood cells (RBCs) that carries oxygen from the lungs to the body tissues, exchanges the oxygen for carbon dioxide, and then carries the carbon dioxide back to the lungs where it is exchanged for oxygen.

Mean Corpuscular Volume (MCV) is the average volume of a red blood cell.

Mean Corpuscular Hemoglobin (MCH) is the average amount of hemoglobin in the average red blood cell.

Mean Corpuscular Hemoglobin Concentration (MCHC) is the average concentration of hemoglobin in a given volume of red cells.

Red Cell Distribution Width Coefficient of variation (RDW CV)is a measurement of the variability of the red blood distribution curve and their mean size. 

The Lipid Profile Test typically measures the levels of total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides. Other results that may be reported include VLDL cholesterol, non-HDL cholesterol, and total cholesterol to HDL cholesterol ratio.

Lipids are fatty acids which store energy for the body and play essential roles in cellular structure and cell signaling. Cholesterols and triglycerides are essential lipids, carried in the blood by lipoprotein particles made up of cholesterol, triglycerides, proteins and phospholipid molecules. The lipoprotein particles are classified according to their densities into High Density Lipoproteins (HDL), Low Density Lipoproteins (LDL), and Very Low Density Lipoproteins (VLDL).

Cholesterol is a fat-like substance formed in the liver, as well as obtained from dietary sources. It is found in all the cells and is an essential part of the structural framework of the cells apart from performing various vital body processes. However, excess cholesterol is harmful. Increased cholesterol in blood can cause it to get deposited on the inner walls of the blood vessels forming plaque.

Triglycerides are the commonest type of fat in the body. Triglycerides are obtained from dietary sources and form the stored fat in adipose tissues. Increase in triglyceride concentration can also give rise to cardiovascular diseases.

High Density Lipoproteins or HDLs are high density particles which help to reduce the chances of cardiovascular diseases by picking up and carrying lipoprotein particles of lower density to the liver for disposal.

Low Density Lipoproteins or LDLs are lipoprotein particles of low density which carry cholesterol to the tissues. Cholesterol carried by LDLs easily comes out of blood and get deposited on the inner walls of the blood vessels, increasing the chances of cardiovascular diseases.

Very Low Density Lipoproteins or VLDLs are lipoprotein particles of very low density which carry triglycerides to the tissues. Excess triglycerides in blood causes increase in VLDL particles which in turn again increases the chance of developing cardiovascular diseases.

Plaque deposition makes the lumen of the blood vessels narrower thereby preventing proper flow of blood and may stop the flow completely. Excessive plaque deposition can also cause the arteries to harden, giving rise to a condition called Atherosclerosis. Improper flow of blood prevents the supply of nutrients and oxygen to the vital organs and may cause heart attack or stroke.

Vitamin D Test measures the levels of Vitamin D in the blood. Two forms of vitamin D can be measured in the blood, 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D. The 25-hydroxyvitamin D is the major form found in the blood and is the relatively inactive precursor to the active hormone, 1,25-dihydroxyvitamin D. Because of its long half-life and higher concentration, 25-hydroxyvitamin D is commonly measured to assess and monitor vitamin D status in individuals.

The 25-hydroxyvitamin D test is done to determine the level of Vitamin D in your blood, whether it is low or higher than normal. Low levels can be seen if a person is not getting enough exposure to sunlight or enough dietary vitamin D to meet his or her body's demand or if there is a problem with its absorption from the intestines (cystic fibrosis, crohn’s disease, who have undergone gastric bypass surgery). Sometimes, medicines used to treat seizure (Phenytoin) can cause Vitamin D deficiency by interfering with transformation to 25-hydroxyvitamin D in the liver. Severe liver and kidney diseases can also cause vitamin D deficiency. High levels reflects excess supplementation of the vitamin.

Urine Routine and Microscopy test involve the three-part evaluation of the urine sample.

1. Gross Examination - It involves the visual examination of the urine sample for color and appearance.

2. Chemical Examination - It is done by urine dip-stick method which involves the use of reagent test strips. These test strips are dipped into the urine sample and the colors that develop are matched with the control for analysis. It is done to examine the urine sample for glucose, protein, pH, specific gravity, blood, nitrites, ketones, leukocyte esterase, bilirubin, and urobilinogen.

3. Microscopic Examination - It involves the examination of the urine sample under the microscope for casts, crystals, cells, bacteria, and yeast. 

LFT measures the level of liver enzymes, proteins, and bilirubin in the blood.

The liver is a wedge-shaped organ located in the right upper part of the abdomen. The liver helps in the synthesis of certain proteins, produces bile (an alkaline compound which helps in the breakdown of fat), process the bilirubin (a yellowish substance produced from the breakdown of hemoglobin) and helps in removing ammonia and other toxins (harmful substances) from the body. It plays an important role in the metabolism of fats, protein, and carbohydrates. It stores glycogen, vitamins, and minerals as well as helps in the metabolism (breakdown) of certain drugs.

Many diseases affect the health of the liver like hepatitis A, hepatitis B, hepatitis C, alcoholic hepatitis, autoimmune hepatitis, cirrhosis, non-alcoholic fatty liver disease (NAFLD), bile duct obstruction, liver or bile duct cancer and many others. Liver function can also be affected by various risk factors like alcohol abuse, certain drugs, sedentary lifestyle, and obesity. Regular monitoring of liver function is essential for early detection of any liver abnormality.

LFT is a group of tests that measure the levels of Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), Alkaline Phosphatase (ALP), Total protein, Bilirubin and Gamma Glutamyltransferase (GGT) in blood. Each component has its own significance and helps to understand a particular aspect of the liver function.

Alanine Aminotransferase (ALT)

 Alanine Aminotransferase (ALT) is an enzyme and this test measures the level of this enzyme in the blood. ALT is also known as serum glutamic-pyruvic transaminase (SGPT) and is mainly found in the liver, but also in smaller amounts in the kidneys, heart, pancreas and muscles. This enzyme is released into the bloodstream in case of liver disease or damage leading to increased ALT blood levels, a specific indicator of liver injury. However, this test cannot determine the extent or severity of the liver damage.

Aspartate Aminotransferase (AST)

This test measures the level of the enzyme AST in your blood. It is also known as serum glutamic-oxaloacetic transaminase (SGOT). AST is found in the liver and is released in the blood in large amounts in case of any liver injury. AST levels are usually measured along with ALT as AST is not specific for liver (also found in the heart, skeletal muscle and other organs). Your doctor may also recommend an ALT/AST ratio to help in the diagnosis.

Alkaline phosphatase (ALP)

This test measures the blood levels of the enzyme ALP which is found in the liver (one of the main source), bile ducts, bones, intestine, pancreas and kidney. ALP helps to break down proteins in the body. Diseases that mainly harm or damage the cells of the liver and bile duct, leading to overproduction and release of this enzyme into the bloodstream. This causes increased blood ALP levels.

Total Serum Protein

This test measures the total amount of protein in the blood, which includes two major types of proteins: albumin and globulin. The test report mentions separate results for total protein, albumin, globulin and albumin/globulin ratio (A/G ratio).

The level of proteins in the blood indicates the biosynthetic capacity of the liver. Hepatocytes (liver cells) are unable to synthesize this protein in certain liver diseases leading to a fall in protein levels in the blood.

Albumin is synthesized only in the liver. It helps to transports minerals, enzymes, hormones, bilirubin and some medicines throughout your body. It prevents the fluid from leaking out of your blood vessels into the tissues.

Globulin is synthesized in the liver and by the cells of the immune system. It plays a key role in fighting infections and transports many enzymes, hormones, minerals and some medicines in the body.

Bilirubin

This test measures the amount of bilirubin in the blood. Bilirubin is a waste product formed by the breakdown of red blood cells and is processed by the liver.

Bilirubin blood test report includes separate values for direct (conjugated) bilirubin, indirect (unconjugated) bilirubin, and total bilirubin.

When heme is released from the hemoglobin, it is converted to bilirubin. This is called unconjugated (indirect) bilirubin which is carried to the liver by some proteins.

In the liver, bilirubin gets attached (conjugated) to modified sugars (glucuronic acid) and form conjugated (direct) bilirubin.

Both these forms can be measured or estimated by laboratory tests, and a total bilirubin result (includes both direct and indirect bilirubin) is also measured.

A damaged liver can’t properly process bilirubin, leading to abnormally high levels of bilirubin in the blood. Increased unconjugated bilirubin in the blood results due to its overproduction or improper uptake by the liver. Increased conjugated bilirubin results can be seen in diseases that reduce the rate of secretion of conjugated bilirubin into the bile or the flow of bile into the intestine resulting in a backward flow of conjugated bilirubin into the blood.

Gamma-glutamyltransferase (GGT)

This test measures the level of the enzyme GGT in your blood which is present in large amounts in the liver. It is a transport molecule and it helps the liver to metabolize many drugs and toxins. GGT is a very sensitive test for detecting any liver disease especially due to alcohol abuse and is also one of the first enzymes to rise in patients with bile duct obstruction like tumor or stones.

The Thyroid Profile Total test measures the levels of the following three hormones in the blood:
Thyroid Stimulating Hormone (TSH)
Thyroxine (T4) - Total
TriIodothyronine (T3) - Total

The thyroid gland (a small, butterfly-shaped gland located in front of the neck) secretes the following hormones:

• Triiodothyronine (T3)

• Thyroxine (T4)

Thyroid Stimulating Hormone (TSH), also called Thyrotropin is a hormone secreted into the blood by the Pituitary gland (a gland present in the brain)). It tells your thyroid gland to make and release the thyroid hormones (T3 & T4) into your blood. The thyroid gland uses the iodine gained from food to make the thyroid hormones.

The thyroid hormones are essential for growth and metabolism. If the thyroid gland produces very high amounts of T3 and T4 hormones, you may experience symptoms like weight loss, rapid heartbeat, tremors, sweating, anxiety, increased sensitivity to heat, etc. and this is known as Hyperthyroidism.

The decreased production of thyroid hormones (T3 and T4) results in Hypothyroidism which may lead to weight gain, fatigue, slow heart rate, increased sensitivity to cold, depression, dry and thin hair, etc.

There is a feedback system in the body to maintain stable amounts of the thyroid hormones (T3 and T4) in the blood. When the levels of thyroid hormone decrease, the pituitary gland is stimulated to release TSH.  High TSH in turn increases the release of T3 and T4 thyroid hormones from the thyroid gland and vice-versa.

T3 and T4 circulate in the blood in two forms:

1) Bound form - It is bound to proteins present in blood and this prevents it from entering the body tissues. The three main proteins in the blood that the thyroid hormones are bound to are albumin, transthyretin and Thyroxine-binding globulin (TBG), also called Thyroid hormone Binding Globulin (THBG).

2) Free form - It enters the body tissues where it is  needed

The total T3 or total T4 includes both bound and free forms circulating in the blood. Hence, thyroid hormones can be measured as Free T3, Total T3, Free T4, and Total T4.

The total T3 and total T4 levels can be affected by the amount of protein available in the blood to bind to them.

This is a test panel done to evaluate the kidney functions. It contains a group of tests integrated to collectively analyze any malfunction related to the kidney.

The kidneys are a pair of bean-shaped organs located on either side of the spinal column in the abdomen towards the back. The kidneys perform a number of important functions. The most important of these is that they filter the blood and separate the waste products generated out of regular metabolic activities of the body, primarily urea. Following the separation, the kidneys excrete the waste products out of the body through urine. They help in maintaining the normal pH level and water balance of the body. The kidneys also play essential roles in the synthesis of Vitamin D and Red Blood Cells (RBCs).

The Kidney Function Test includes the following tests to monitor kidney function:

·        Blood Urea Nitrogen (BUN)/ Urea:

Blood Urea Nitrogen is a test to measure the amount of urea nitrogen present in the blood. Urea is a nitrogenous by-product formed by the metabolism of protein, and its level in blood serves as an indication of the amount of nitrogen present in blood as urea. In simpler terms, BUN is the measure of the amount of nitrogen present in blood in the form of urea. High BUN levels in the blood can be caused as a result of kidney diseases, dehydration and obstruction in the urinary tract due to kidney stones, prostate gland enlargement, etc.

Urea test measures the level of urea in the blood. Urea is a final waste product formed from the breakdown of proteins. Urea is filtered out of the blood by the kidneys to excrete excess nitrogen present in the blood through urine. Excess of urea in blood is called uremia and can be caused by a number of conditions including kidney diseases.

·         Uric Acid:

This test measures the level of uric acid in the blood. Uric acid is a waste product formed from the breakdown of purines, which are essential building blocks of DNA. It is also produced by the metabolism of proteinaceous food, especially red meat. Uric acid is excreted from the body by the kidneys through urine and a small portion through stool. Although indirectly but uric acid test helps in estimating the proper functioning of the kidneys, .

The presence of excess amounts of uric acid in the blood is called hyperuricemia. This accumulation of uric acid crystals in the synovial fluid between joints lead to the formation of gouts. Hyperuricemia also causes the formation of hard lumps of uric acid crystals called tophi under the skin and at the top of the ears. Uric acid crystals can also accumulate in the kidneys and cause kidney stones.

·         Creatinine:

This test measures the level of Creatinine in blood. Creatinine is a waste product formed from the normal breakdown of muscles in the body. Creatinine is almost completely excreted by the kidneys, so their levels in the blood serve as an indication of improper kidney function.

The levels of creatinine in the blood can rise due to decreased elimination from the kidneys as well as due to increased creatinine production by muscular breakdown, eating cooked meat, protein supplements, etc.

·         BUN/Creatinine Ratio:

BUN/Creatinine Ratio compares the levels of nitrogen as urea in the blood to the levels of creatinine in the blood. This ratio serves as a more accurate representation of kidney function. An increase in the ratio can be seen in case of dehydration while creatinine levels remain the same. Low BUN to creatinine ratio can be caused due to a low protein diet, liver cirrhosis, rhabdomyolysis (muscle disease), syndrome of inappropriate antidiuretic hormone secretion (SIADH) as well as during pregnancy.

Electrolytes: The serum electrolyte test measures the following electrolytes:

• Sodium (Na+)

• Potassium (K+)

• Chloride (Cl-)

Electrolytes play an important role in a number of body functions like metabolism, neuromuscular functioning, maintaining hydration, and pH (acid-base balance). Electrolytes also help in the entry of nutrients into the cells and removal of waste products from the cells. Electrolytes carry an electrical charge which can be either negative or positive and exist as dissolved salts in blood and body tissues. The Serum Electrolyte test measures the following important electrolytes:

Sodium (Na+)

Sodium is an essential body electrolyte which, along with potassium, chloride, bicarbonate, etc.helps to maintain the normal fluid and pH balance of the body. It is also vital for cellular metabolism, and in the activity of nerves and muscles and transmission of impulses between them. Sodium is present in all the body fluids. The highest concentration of sodium is found in blood and extracellular fluid.

Sodium is supplied to the body principally through dietary salt (sodium chloride or NaCl), and a small portion of sodium is absorbed through other food items. The required portion is absorbed by the body and the remaining is excreted by the kidneys through urine. The body maintains a very narrow range of sodium concentration by three mechanisms:

·         Secretion of hormones natriuretic peptides and aldosterone to control sodium elimination through urine

·         Secretion of antidiuretic hormone (ADH), also called Vasopressin, to control the volume of water eliminated through urine

·         Induction of thirst

Any disruption in the above-mentioned mechanisms gives rise to an imbalance in the concentration of sodium in the blood to produce Hyponatremia (low blood sodium concentration), or Hypernatremia (high blood sodium concentration). Both these conditions produce a number of symptoms and may even lead to death.

Potassium (K+)

Potassium is one of the essential body electrolytes along with sodium, chloride, bicarbonate, etc. As an electrolyte, potassium helps to regulate the amount of fluids present in the body and to maintain a correct pH balance. It performs a vital role in cellular metabolism and transport of nutrients and waste products in and out of cells. It is also essential in the transmission of nerve impulses to muscles and muscle activity.

Sufficient amount of potassium required by the body is absorbed from dietary sources, and the remaining unabsorbed potassium is excreted by the kidneys. The hormone called aldosterone maintains the body potassium level within a small normal range. Aldosterone acts on the nephrons present in the kidneys and activates a sodium-potassium pump which helps the body to reabsorb sodium and excrete potassium. This helps to maintain the potassium concentration in the blood within its normal range. Deviation of potassium concentration from its normal range gives rise to Hyperkalemia (high potassium level in blood), or Hypokalemia (low potassium level in blood). Both these conditions may produce a number of symptoms, and may even be fatal if not controlled.

Chloride (Cl-)

Chloride is an essential mineral which acts as an electrolyte similar to potassium, sodium, bicarbonate, etc. It helps to maintain the normal fluid and electrolyte balance in the body. It also acts as a buffer to help maintain the pH balance of the body. It also plays an essential role in metabolism by producing hydrochloric acid (HCl) in the stomach for digestion. The highest concentration of chloride is found in blood and extracellular fluid (fluid present outside the cells).

Most of the chloride is supplied to the body through dietary salt (sodium chloride or NaCl), and a small portion is absorbed through other food items. The required portion is absorbed by the body and the remaining is excreted by the kidneys through urine. The concentration of chloride in blood is maintained within a very narrow range by the body. Its increase or decrease is directly correlated with the sodium levels.
