what is rft test

Renal Function Test (RFT) is a group of tests that may be performed together to evaluate kidney (renal) function. The RFT test is a series of tests that measures the health of your kidneys. The tests measure levels of various components in the blood, including blood urea nitrogen (BUN), estimated glomerular filtration rate (eGFR), and serum creatinine. The function of healthy kidneys in a human body is to remove waste products and excess fluid from the body. If the kidneys are not functioning properly, waste products can accumulate in the blood and fluid levels can increase to dangerous volumes, causing damage to the body or a potentially life-threatening situation. The RFT test is usually given to people who have high blood pressure, diabetes, kidney disease, or other conditions that can affect kidney function. The test is also useful to assess the renal function, stage level or type of renal disease, and to monitor the progression of renal disease to ensure that optimal management occurs and to monitor response to interventions.
