Kidney Function Test Normal Range — KFT/RFT Values
Understand your Kidney Function Test (KFT/RFT) report — normal values, what abnormal results mean, and when to get tested.
What is Kidney Function Test (KFT/RFT)?
A Kidney Function Test (KFT), also called Renal Function Test (RFT), measures how well the kidneys are filtering waste from the blood. 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?
Serum Creatinine
Reduced kidney function, dehydration, high muscle mass, kidney disease
Low muscle mass, liver disease, pregnancy
Blood Urea Nitrogen (BUN)
Kidney disease, dehydration, high-protein diet, GI bleeding, heart failure
Liver disease, malnutrition, overhydration
Uric Acid
Gout, kidney stones, kidney disease, high-purine diet, alcohol use
Low purine diet, certain medications
Sodium (Na)
Dehydration, diabetes insipidus, excess salt intake
Diarrhoea, vomiting, kidney disease, heart failure, liver cirrhosis
Potassium (K)
Kidney failure, medications (ACE inhibitors), tissue damage, acidosis
Diarrhoea, vomiting, diuretic use, poor dietary intake
eGFR (Estimated Glomerular Filtration Rate)
Not usually a concern
Kidney disease staging: 60-89 = mild, 30-59 = moderate, 15-29 = severe, below 15 = kidney failure
Calcium
Hyperparathyroidism, cancer, vitamin D excess, dehydration
Vitamin D deficiency, hypoparathyroidism, kidney disease, malnutrition

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.
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.
