- Serum Creatinine Test – This test determines creatinine levels in the bloodstream.
- Blood Urea Nitrogen (BUN) Test – This test determines the level of nitrogen in the blood.
- Glomerular Filtration Rate (GFR) Test – This determines how effectively your kidneys filter waste.
How Many Tests Are in RFT?
A “Renal Function Test (RFT)” includes multiple tests like creatinine, urea, BUN, GFR, electrolytes, and urine analysis to assess kidney function.
What is a Normal Renal Function?
A normal renal function means that your kidneys are efficiently removing waste and maintaining a proper balance of fluids and electrolytes in the body.
How Much RFT is Normal?
Normal values for RFT tests:
- – Serum Creatinine: 0.6-1.2 mg/dL (for men); 0.5-1.1 mg/dL (for women).
- Blood Urea Nitrogen (BUN): 7–20 mg/dL
— GFR: More than 90 mL/min is considered normal.
What is Poor Renal Function?
Poor renal function means your kidneys are not filtering waste properly. This can be due to chronic kidney disease (CKD), dehydration, or other medical conditions.
What is the RFT Test Cost?
