Kidney Function Test

Kidney Function Tests are tests that measure how well the kidneys are functioning. The kidneys are two bean-shaped organs located in the lower back on either side of the spine. They are responsible for filtering waste products and excess fluids from the body. Kidney Function Tests (KFTs) measure the levels of waste products, electrolytes, and other substances in the blood and urine. They can also measure how well the kidneys are able to filter out these substances.

KFTs can help diagnose and monitor conditions such as kidney disease, diabetes, hypertension, infections, and electrolyte imbalances. The most common KFTs include creatinine, urea nitrogen, and electrolyte tests. Creatinine is a waste product that is produced when muscle tissue breaks down. Urea nitrogen is produced when proteins are broken down. Electrolytes are minerals that help regulate fluid balance in the body.

In order to perform a KFT, blood and urine samples are taken and analyzed for specific substances. Blood samples are taken from a vein in the arm. These samples are then sent to a laboratory for analysis. Urine samples can also be taken and sent to a laboratory for further testing.
