Understand your Kidney Function Test (KFT/RFT) report — normal values, what abnormal results mean, and when to get tested.
हिंदी में पढ़ें: Kidney Function Test नॉर्मल रेंज →What is Kidney Function Test (KFT/RFT)?
A Kidney Function Test (KFT) measures how well the kidneys are filtering waste from the blood. RFT (Renal Function Test) is the same test as KFT — labs in India use both names for the same panel of creatinine, urea, uric acid, and electrolytes. The kidneys filter about 200 litres of blood daily, removing waste products and excess fluids. KFT is essential for people with diabetes, hypertension, or those on medications that can affect the kidneys. Early detection of kidney problems is critical because kidney damage is often silent until advanced stages.
Kidney Function Test (KFT/RFT) Normal Range Chart
| Parameter | Normal Range | Unit |
|---|---|---|
| Serum Creatinine | Men: 0.7–1.3 mg/dL | Women: 0.6–1.1 mg/dL | mg/dL |
| Blood Urea Nitrogen (BUN) | 7–20 mg/dL | mg/dL |
| Uric Acid | Men: 3.4–7.0 mg/dL | Women: 2.4–6.0 mg/dL | mg/dL |
| Sodium (Na) | 136–145 mEq/L | mEq/L |
| Potassium (K) | 3.5–5.0 mEq/L | mEq/L |
| eGFR (Estimated Glomerular Filtration Rate) | Above 90 mL/min/1.73m² | mL/min |
| Calcium | 8.5–10.5 mg/dL | mg/dL |
* Reference ranges may vary slightly between laboratories. Always interpret results with your doctor.
What Do Abnormal Results Mean?

What is the normal creatinine level?
Normal serum creatinine is 0.7–1.3 mg/dL for men and 0.6–1.1 mg/dL for women. Creatinine above these levels suggests reduced kidney function. However, it should be interpreted along with eGFR for accurate assessment.
What does high creatinine mean?
High creatinine means the kidneys are not filtering waste efficiently. Common causes include chronic kidney disease, dehydration, high-protein diet, intense exercise, and certain medications. Persistent elevation needs medical evaluation.
What is eGFR and what should it be?
eGFR (estimated Glomerular Filtration Rate) measures how well your kidneys filter blood. Normal is above 90. eGFR 60-89 is mildly reduced, 30-59 is moderately reduced, 15-29 is severely reduced, and below 15 indicates kidney failure.
What is RFT test and what should it be?
RFT (Renal Function Test) is simply another name for KFT (Kidney Function Test). It measures serum creatinine, blood urea, BUN, uric acid, sodium, potassium, and eGFR. A normal RFT report shows creatinine 0.7–1.3 mg/dL (men) or 0.6–1.1 mg/dL (women), urea 15–40 mg/dL, and eGFR above 90. If any value is outside this range, consult a physician for kidney evaluation.
How often should KFT be done?
Annually for healthy adults. Every 3-6 months if you have diabetes, hypertension, or known kidney disease. More frequently if on medications that can affect kidneys.
How much does KFT cost in Bhopal?
KFT cost in Bhopal ranges from ₹300 to ₹800. At R.K. Hospital, Indrapuri, KFT is available with same-day reports. Call 0755-4260605.
