RFT stands for Renal Function Test, which is a group of tests that evaluate kidney function by measuring levels of various components found in blood). The tests are used to assess how well the kidneys are removing waste products from the body and maintaining the right balance of electrolytes like potassium, sodium, and chloride in the bloodstream. The most practical tests to assess renal function are to get an estimate of the glomerular filtration rate (GFR) and to check for proteinuria (albuminuria) ). The GFR is the rate at which substances in plasma are filtered through the glomerulus, and it is the best test to assess glomerular function). The RFT panel typically includes a combination of specific tests that collectively offer a comprehensive evaluation of renal health. The tests are used to diagnose kidney diseases, monitor their progression, and evaluate the effectiveness of treatment. RFT tests are usually prescribed by a doctor when there are signs and symptoms of kidney damage or kidney disease, such as changes in urine appearance, quantity, and frequency, fatigue, fever, swelling in the hands and feet, and pain during urination.
