test normal rangeKidney Function Test Normal Range:

The normal range for Renal Function test values may vary depending on the specific parameters being measured, individual laboratory reference values, and factors such as age and gender. Common parameters include blood urea nitrogen (BUN), creatinine, and estimated glomerular filtration rate (eGFR). 

Below is the reference table for Kindney function test normal values:

Parameter Normal Range
Serum Creatinine 0.6 – 1.2 mg/dL (men)

0.5 – 1.1 mg/dL (women)

Blood Urea Nitrogen 8 – 20 mg/dL
Glomerular Filtration Rate (GFR) > 90 mL/min/1.73m²
Serum Uric Acid 3.5 – 7.2 mg/dL
Serum Potassium 3.5 – 5.1 mEq/L
Serum Sodium 135 – 145 mEq/L
Serum Chloride 96 -106 mEq/L
Serum Albumin 3.4 – 5.4 g/dL

what is the testWhat is KFT or RFT?
