Urinary Tract Infection Panel near me in Chennai

The urine culture & sensitivity test is performed to detect and diagnose a microbial infection of the urinary tract. The metabolic processes in the body produce products called metabolites which are present in the blood. Some of them are utilized by cells, while others are wastes which are filtered out of the blood by the kidneys in urine. Urine produced by the kidneys passes through ureters into the urinary bladder where it is stored until the urinary bladder is full. Once full, the urinary bladder releases the urine through another tube called urethra to the outside of the body. The pathway followed by urine from the kidneys to the outside is called the urinary tract. The urinary tract may be infected by some microorganisms causing various conditions. Urine is normally sterile, but if urinary tract infection occurs, the pathogenic microorganism may be found in urine. A urine sample is collected and cultured to detect such an infection and to identify the microorganism causing it.

The collected urine sample is placed on an agar medium (nutrient solution mixed with agarose gel) and incubated at body temperature for 24 to 48 hours. This allows the growth of the microorganisms in the sample if any. Growing microorganisms form different types of colonies on the agar which are studied further in a laboratory to determine the exact microbe causing the UTI.

Once the pathogen is identified, antibiotic susceptibility test is performed to guide treatment for the UTI being tested for. This may be done in two ways. The conventional method involves the use of small filter paper discs with antibiotic of known concentration and placing them on agar plate where the pathogen is cultured. The antibiotic creates a small area around the discs where the microorganisms do not form colonies. The radius of this zone is measured to estimate the efficacy and strength of that antibiotic in treating the UTI. The other method involves an automated machine to detect the sensitivity pattern to find out which antibiotic can be used to treat the infection.

A Uric Acid test determines the level of uric acid in your body. Uric acid is a nitrogenous compound produced by the metabolic breakdown of purine. Purines are present as nitrogenous bases in the DNA and are also found in food like red meat and seafood.

Most uric acid dissolves in the blood and goes into your kidneys. From there, it passes through your body via the urine. Decreased elimination of uric acid is often a result of impaired kidney function due to kidney disease. In many cases, the exact cause of excess uric acid is unknown. Doctors seldom need to test for low levels of uric acid.

A Blood Urea Nitrogen test measures the levels of urea nitrogen in the blood. Blood urea is a waste product that is formed in the liver when you eat food and the protein is metabolized into amino acids. This process leads to the production of ammonia that is further converted into urea. Both ammonia and urea are nitrogenous compounds. Your liver releases urea into the blood which is then carried out to the kidneys. In the kidneys, urea is filtered from the blood and flushed out of the body via urine. This is a continuous process, so a small amount of urea nitrogen always remains in the blood.

In the case of a kidney or liver disease, there is a change in the amount of urea present in the blood. If your liver produces urea in an increased amount or if there is any problem in kidney functioning, there might be difficulty in filtering out the waste products from the blood, which can result in increased urea levels in the blood.
