The Renal Function Test (RFT), also known as the Kidney Function Test (KFT), is a panel of blood tests designed to evaluate how well your kidneys are functioning. Kidneys play a crucial role in filtering waste, balancing electrolytes, and regulating fluid levels in the body. When the kidneys are impaired due to illness or damage, waste products such as urea and creatinine accumulate in the bloodstream. This test measures several key biomarkers in the blood, including sodium, potassium, chloride, bicarbonate, urea, creatinine, and calcium, to assess overall kidney health. It is commonly prescribed for people with symptoms of kidney issues or as part of a routine health checkup for individuals at risk of kidney disease.

Abnormal results in the Renal Function Test can indicate potential health risks, especially related to kidney function. High levels of urea or creatinine can suggest that the kidneys are not effectively filtering waste from the blood, a sign of kidney disease or kidney failure. Electrolyte imbalances, such as high potassium levels (hyperkalemia), can also be dangerous and lead to complications such as heart problems. Early detection through the Renal Function Test can help manage and reduce the risks of kidney disease, diabetes, high blood pressure, or other underlying conditions that affect kidney health.
