Kidney Function Test (KFT) in Gurgaon

At a Glance

Profile: Kidney Function Test (KFT). Tests: 12 parameters. Price: From 390. Fasting: Not required. Sample: Serum. Reports: 24 hours, digital. Home collection: Available across Gurgaon. Lab: NABL-accredited. The Kidney Function Test (KFT) is what a doctor asks for when creatinine or uric acid is raised on an earlier report, when you have diabetes or high blood pressure, when you take medicines that the kidneys clear, or when you have swollen ankles, foamy urine or recurring kidney stones. It needs no fasting, so it can be done on a working day without changing breakfast. ## How the Kidneys Are Assessed Creatinine is the central value. It is a muscle by-product filtered by the kidneys, and it rises when filtration falls. The limit to know is that creatinine rises late: a substantial share of kidney function can be lost before the number leaves its reference range. GFR by MDRD Formula converts creatinine, age and sex into an estimated filtration rate, which is more informative than creatinine alone but remains an estimate, less reliable in very muscular or very thin people. Urea, Blood Urea Nitrogen (BUN), BUN / Creatinine ratio and Urea / Creatinine Ratio are three views of the same nitrogen waste. Urea and BUN measure the same compound expressed differently. The ratios help a doctor separate dehydration, where urea rises disproportionately, from true kidney disease. ## Uric Acid and the Kidney Link Uric Acid is a waste product of purine breakdown. High values are linked to gout and to some kidney stones, and are raised by dehydration, alcohol, rich meals and some medicines. A single raised value does not mean gout; many people with high uric acid never develop it. A doctor reads the number alongside symptoms and creatinine. ## Electrolytes and Minerals Sodium, Potassium and Chloride are the body's main electrolytes. Potassium matters most: if it runs high in kidney disease, heart rhythm can be affected. A sample that is damaged in the tube can falsely raise potassium, which is why an unexpected high is often repeated. Calcium and Phosphorus - Serum are mineral values that shift in advanced kidney disease and in some bone and parathyroid conditions. ## Desk Days, Dehydration and Diabetes In a Gurgaon office, the common habit is long hours at a desk with less water than the body needs, and an air-conditioned room hides thirst. Mild dehydration can push urea, BUN and uric acid up for a day and exaggerate a creatinine reading. Drinking water as usual on the day of the test is sensible. Diabetes is the other large risk: 101 million Indian adults have it (Anjana RM, Mohan V, et al., ICMR-INDIAB, Lancet Diabetes & Endocrinology, 2023;11(7):474–489), and the kidney is one of the organs it affects. ## Medicines and Supplements Regular anti-inflammatory painkillers, some antibiotics and certain blood pressure tablets can affect kidney values, and creatine or protein supplements taken for the gym can raise creatinine without any kidney damage. Tell the phlebotomist what you take and continue prescribed medicines unless your doctor advises otherwise. A creatinine slightly above range is often repeated after a few days of normal fluids before anything further is done. ## Buying More Than One Panel The Kidney Function Test (KFT) is included in every full body package, starting with the Basic Full Body Checkup (77 parameters), together with the Liver Function Test (LFT), Lipid Profile and Complete Blood Count (CBC) + ESR. If you need several panels, a package costs less than separate bookings. The trade-off is that packages contain fasting tests needing 10 hours without food, whereas this profile does not. ## What Is Not Included No urine test of any kind. A routine urine dipstick detects overt protein loss but not microalbuminuria, and early diabetic kidney damage needs a separate urine microalbumin / ACR test. Also not included are cystatin C, Magnesium, Bicarbonate, parathyroid hormone, Vitamin D, kidney ultrasound or a stone workup. A normal KFT does not exclude early kidney damage. ## Sources Anjana RM, Mohan V, et al. ICMR-INDIAB, Lancet Diabetes & Endocrinology, 2023;11(7):474–489 Content last reviewed: October 2026

Fasting: Not required. Eat and drink normally; the sample can be given at any time of day. Sample: A single venous blood draw, processed as serum. All 12 parameters run from that one sample. Water: Drink fluids as usual. Dehydration can raise urea, BUN, uric acid and creatinine for a day. Medicines: Continue prescribed medicines unless your doctor says otherwise. Tell the phlebotomist about painkillers, water tablets, blood pressure medicines and creatine or protein supplements, which can change kidney values. Exercise and diet: Avoid unusually hard exercise the day before, and a very large meat-heavy meal the evening before, as both can nudge creatinine and uric acid. Home collection: Available across Gurgaon, including Sector 14, 29, 38, 42, 44, 46, 49, 54, 55, 56, 57, Golf Course Road, Golf Course Extension, Sohna Road, DLF Phase 1–5, Udyog Vihar, Palam Vihar and South City.
