Healthy kidneys remove wastes and excess fluid from the blood. Renal Profile tests are performed to evaluate the function of the kidney. They measure the amount of electrolytes in the blood to determine the status of the kidney. The analytes that are tested for are Sodium, Potassium, Chloride, Bicarbonate, Urea, Creatinine and eGFR. These tests helps in early detection of malfunctioning kidneys.
