Kidney Function Test (KFT/RFT) Cost in India 2026: Price Guide for All Cities
Kidney function test price in India is an increasingly important question as the country faces a silent epidemic — Chronic Kidney Disease (CKD) affects approximately 17% of Indians, and most cases are detected only when significant kidney damage has already occurred. For the millions of Indians living with diabetes or hypertension (the two leading causes of CKD), regular KFT monitoring is as essential as monitoring blood sugar or blood pressure, yet many families skip it due to cost concerns or lack of awareness.

What Does a Kidney Function Test Include?
A standard KFT/RFT panel typically includes 8–12 parameters. Here is what each measures and why it matters:
Core KFT Parameters
| Test | What It Measures | Normal Range (Indian Adults) |
|---|---|---|
| Serum Creatinine | Waste product filtered by kidneys | Men: 0.7–1.3 mg/dL; Women: 0.6–1.1 mg/dL |
| Blood Urea Nitrogen (BUN) | Nitrogen from protein breakdown | 7 – 25 mg/dL |
| Serum Urea | Urea in blood | 15 – 40 mg/dL |
| Uric Acid | Breakdown product of purines | Men: 3.5–7.2 mg/dL; Women: 2.6–6.0 mg/dL |
| eGFR (Estimated GFR) | Calculated kidney filtration rate | > 60 mL/min/1.73m² (ideally > 90) |
| Sodium (Na+) | Electrolyte balance | 136 – 145 mEq/L |
| Potassium (K+) | Electrolyte balance | 3.5 – 5.0 mEq/L |
| Chloride (Cl-) | Electrolyte balance | 98 – 107 mEq/L |
| Bicarbonate (HCO3-) | Acid-base balance | 22 – 29 mEq/L |
| Calcium | Bone and kidney health | 8.5 – 10.5 mg/dL |
| Phosphorus | Kidney-bone axis | 2.5 – 4.5 mg/dL |
Additional Tests Often Ordered Alongside KFT
- Urine Routine and Microscopy: Checks for protein (proteinuria — early CKD sign), blood, pus cells, and casts
- Spot Urine Albumin-to-Creatinine Ratio (UACR): The most sensitive early marker of diabetic kidney disease — detects microalbuminuria before creatinine rises
- 24-Hour Urine Protein: Quantifies protein loss; used in nephrology follow-up
KFT Test Price by City in India
| City | Govt Hospital | Private Lab | Diagnostic Chain |
|---|---|---|---|
| Mumbai | ₹100 – ₹250 | ₹400 – ₹900 | ₹250 – ₹600 |
| Delhi | ₹100 – ₹250 | ₹380 – ₹850 | ₹220 – ₹550 |
| Bangalore | ₹100 – ₹250 | ₹400 – ₹900 | ₹240 – ₹580 |
| Chennai | ₹100 – ₹230 | ₹370 – ₹850 | ₹230 – ₹560 |
| Hyderabad | ₹100 – ₹230 | ₹360 – ₹830 | ₹220 – ₹550 |
| Pune | ₹100 – ₹240 | ₹380 – ₹870 | ₹230 – ₹570 |
| Kolkata | ₹80 – ₹200 | ₹320 – ₹750 | ₹200 – ₹500 |
Prices as of March 2026. May vary by lab.
Individual creatinine tests are significantly cheaper than the full KFT panel: serum creatinine alone costs ₹80–₹200 at private labs and ₹30–₹60 at government hospitals. For annual monitoring in stable CKD, some doctors order creatinine + urea + uric acid + electrolytes individually — ask your nephrologist what is necessary.
Understanding eGFR: The Most Important Kidney Number
The estimated Glomerular Filtration Rate (eGFR) tells you what percentage of normal kidney function you have. It is calculated from your creatinine level, age, sex, and race using validated equations (CKD-EPI or MDRD).
CKD Staging by eGFR
| CKD Stage | eGFR (mL/min/1.73m²) | Kidney Function | Action Required |
|---|---|---|---|
| Stage 1 | ≥ 90 | Normal or near-normal | Monitor if risk factors present |
| Stage 2 | 60 – 89 | Mildly decreased | Monitor; control BP and blood sugar |
| Stage 3a | 45 – 59 | Mildly to moderately decreased | Nephrology referral; dietary changes |
| Stage 3b | 30 – 44 | Moderately to severely decreased | Urgent nephrology care |
| Stage 4 | 15 – 29 | Severely decreased | Prepare for dialysis/transplant planning |
| Stage 5 | < 15 | Kidney failure | Dialysis or transplant needed |
Critical fact for Indian patients: A "normal" creatinine value does not mean kidneys are healthy. A creatinine of 1.1 mg/dL in a 70-year-old woman with small muscle mass may correspond to an eGFR of only 55 mL/min — Stage 3a CKD. Always ask for the eGFR, not just creatinine.
Normal Ranges and What Abnormal Values Mean
Creatinine
Creatinine is a muscle waste product filtered exclusively by the kidneys. When kidneys are damaged, creatinine builds up in blood.
- High creatinine: Kidney damage (acute or chronic), dehydration, high protein diet, rhabdomyolysis (muscle breakdown)
- Low creatinine: Low muscle mass, malnutrition, pregnancy
Indian-specific note: Indian men and women have lower average muscle mass than Western populations. A creatinine of 1.3 mg/dL may be "within normal range" on a lab report but could indicate CKD Stage 3 in a small-framed Indian woman aged 65.
Uric Acid
Elevated uric acid (hyperuricaemia) causes gout and is also an independent risk factor for kidney disease, hypertension, and cardiovascular disease.
- High uric acid: Gout, kidney disease, high purine diet (red meat, shellfish), alcohol, diuretics
- Common in India among men who drink alcohol and eat red meat
Electrolytes (Sodium and Potassium)
- High potassium (hyperkalemia > 5.5 mEq/L): Dangerous in CKD — can cause fatal heart arrhythmias; common in Stage 4–5 CKD
- Low sodium (hyponatremia < 135 mEq/L): Indicates fluid imbalance; can cause confusion and seizures
- Electrolyte monitoring becomes critical as CKD progresses
Who Should Get a KFT Test and How Often?
Annual KFT Testing Is Essential for:
Diabetics: Diabetic nephropathy is the leading cause of CKD in India. The ICMR recommends annual KFT + UACR testing for all diabetics from the time of diagnosis. Detecting microalbuminuria (early protein in urine) is crucial — at this stage, kidney disease is still reversible with tight blood sugar and blood pressure control.
Hypertensive patients: Hypertension is the second leading cause of CKD. Annual creatinine and urine protein check is mandatory for all hypertensives on treatment.
Frequent NSAID users: Pain killers like ibuprofen (Brufen), diclofenac (Voveran), and aspirin used regularly cause analgesic nephropathy — a common but underrecognised cause of CKD in India. Annual KFT is advisable.
People with a family history of kidney disease: CKD clusters in families, partly through genetic conditions (ADPKD — polycystic kidney disease) and partly through shared risk factors.
Age > 60: Age-related decline in kidney function (normal) means eGFR should be monitored annually.
How Often to Test
| Situation | Recommended Frequency |
|---|---|
| Healthy adult, no risk factors | Every 3–5 years |
| Diabetic, no kidney signs | Annually |
| Hypertensive | Annually |
| CKD Stage 1–2 | Every 6–12 months |
| CKD Stage 3 | Every 3–6 months |
| CKD Stage 4–5 | Every 1–3 months |
| On nephrotoxic medications (NSAIDs, contrast dye) | Before and after treatment |
| After acute illness with dehydration | Once recovered |
Why Early KFT Testing Saves Money and Lives
CKD is called a "silent killer" because it causes no symptoms until > 60–70% of kidney function is lost. By the time patients develop swelling, breathlessness, and fatigue, they may already be in Stage 4–5 CKD. Dialysis costs ₹10,000–₹30,000 per month in India — an enormous financial burden for most families. A KFT costing ₹300–₹900 once or twice a year is negligible compared to this.
Early detection allows:
- Tight blood sugar and blood pressure control (slows CKD progression significantly)
- Medication adjustments (some drugs are harmful to kidneys)
- Dietary changes (protein restriction in later stages)
- Kidney transplant planning (preferred over lifelong dialysis)

Frequently Asked Questions
Q: Is creatinine test the same as a kidney function test?
No. A serum creatinine test measures one specific waste product. A kidney function test (KFT) or renal function test (RFT) is a panel that includes creatinine, urea, uric acid, electrolytes (sodium, potassium, chloride), and sometimes eGFR calculation and calcium/phosphorus. The full panel gives a much more complete picture of kidney health.
Q: What is a normal creatinine level in India?
Normal serum creatinine for Indian adults is approximately 0.7–1.3 mg/dL for men and 0.6–1.1 mg/dL for women. However, these ranges are derived from Western populations. For small-framed Indian women, a creatinine of 1.0–1.1 mg/dL may already indicate reduced kidney function. Always ask your doctor to calculate your eGFR rather than relying on creatinine alone.
Q: Can drinking more water improve my KFT results?
Mild dehydration can falsely elevate creatinine. Ensure you are well-hydrated before your test — drink 2–3 glasses of water the morning of your test. However, drinking excess water will not improve genuinely elevated creatinine due to kidney disease. If creatinine is elevated on repeat testing despite adequate hydration, this indicates actual kidney dysfunction requiring medical evaluation.
Q: Should diabetics get KFT every year even if they feel fine?
Absolutely yes. This is one of the most important annual tests for diabetics, alongside an eye examination (fundus), foot examination, HbA1c, and urine albumin (microalbuminuria test). The ICMR and Research Society for the Study of Diabetes in India (RSSDI) both mandate annual KFT + UACR for all diabetics. Diabetic nephropathy causes no symptoms until kidney function is severely compromised.
Q: Does the KFT test require fasting?
Fasting is preferred (4–6 hours) but not strictly required for most KFT parameters. Creatinine and urea are minimally affected by recent food intake. Uric acid can be slightly elevated after a high-purine meal. For the most accurate results and to keep testing conditions consistent across serial tests, a 4–6 hour fast is recommended. Avoid heavy protein meals the day before.
Q: What foods should I avoid before a kidney function test?
Avoid high-protein foods (meat, eggs, dal in large quantities) and high-purine foods (organ meats, shellfish, beer) for 24 hours before the test, as these can transiently elevate creatinine and uric acid. Stay well-hydrated with water. Avoid vigorous exercise for 24 hours before the test — exercise temporarily raises creatinine. Inform the lab about any NSAIDs or kidney-affecting medications you are taking.
Q: Is kidney function test covered under Ayushman Bharat?
Under PM-JAY (Ayushman Bharat), KFT is covered as part of inpatient diagnostic workup. For outpatient screening, many government hospitals and health and wellness centres offer KFT at nominal charges of ₹50–₹100. Under the National Programme for NCD Prevention and Control, kidney disease screening is being progressively included in government primary care.
