High Phosphorus (Hyperphosphatemia > 4.5 mg/dL) binds with calcium in kidney disease patients, causing calcification of arteries and heart valves. Parhez: dairy products, cola drinks, chocolate, and processed meats.

Complete Medical Guide to Kidney Function Tests (KFT / RFT)
A Kidney Function Test (KFT), also commonly referred to as a Renal Function Test (RFT), is an essential panel of blood tests that evaluates how efficiently your kidneys are filtering metabolic waste products, maintaining electrolyte equilibrium, and regulating fluid volume.
7 Warning Signs of Kidney Problems (गुर्दे की खराबी के लक्षण)
Kidney diseases are often termed "silent killers" because early stages produce few symptoms. Watch out for:
Edema (Soojan): Swelling around the eyes, face, ankles, or feet.
Foamy Urine: Excessive bubbles or froth indicating albumin/protein leakage.
Hematuria: Reddish or cola-colored urine indicating blood leakage.
Unexplained Fatigue: Kidneys produce erythropoietin (EPO); failing kidneys cause severe anemia and weakness.
Frequent Urination at Night (Nocturia): Having to wake up multiple times to pass urine.
Metallic Taste & Loss of Appetite: Urea buildup (uremia) alters food taste and causes nausea.
Persistent Itchy Skin: Phosphorus accumulation causing severe skin pruritus.

Frequently Asked Questions (FAQs)
Clinically verified answers to patient queries regarding normal ranges, report interpretation, and lifestyle management.
What is considered a normal Serum Creatinine level in India?
Normal Serum Creatinine is 0.7 to 1.3 mg/dL for adult males and 0.5 to 1.1 mg/dL for adult females. Creatinine is a waste product of muscle metabolism excreted by the kidneys. Values consistently above 1.4 mg/dL indicate reduced kidney filtration capacity and require immediate medical evaluation.
What is eGFR and how is it used to stage Chronic Kidney Disease (CKD)?
eGFR (Estimated Glomerular Filtration Rate) measures how many milliliters of blood your kidneys filter per minute. Normal eGFR is >90 mL/min/1.73m². CKD is staged from Stage 1 (>90 with kidney damage), Stage 2 (60-89), Stage 3a (45-59), Stage 3b (30-44), Stage 4 (15-29 severe reduction), to Stage 5 (<15 Kidney Failure).
Kya KFT test se pehle fasting rehna zaroori hota hai?
KFT (Kidney Function Test) me Serum Creatinine aur Urea ke liye sakht fasting zaroori nahi hoti, lekin test se 24 ghante pehle excessive red meat ya protein supplements nahi lene chahiye kyunki isse creatinine temporarily badh sakta hai. Hydrated rehna zaroori hai.
Creatinine high hone ke aam lakshan kya hote hain?
Creatinine badhne par shuruat me koi lakshan nahi hote. Lekin jab filtration kam hoti hai to ankhon ke niche aur pairon me sujan (edema), thakaan, peshab me jhaag (frothy urine), raat me baar-baar peshab aana, aur high blood pressure jaisi pareshaniyan ho sakti hain.
Blood Urea aur BUN me kya antar hota hai?
BUN (Blood Urea Nitrogen) urea me mojud nitrogen ka hissa hota hai. India me aam taur par Blood Urea report kiya jata hai (Normal: 15-40 mg/dL). BUN = Blood Urea / 2.14 hota hai. Dehydration ya high-protein diet se Blood Urea jaldi badh jata hai bina kidney damage ke.
Serum Uric Acid badhne par kya bimari hoti hai?
Normal Uric Acid 3.5 to 7.2 mg/dL (men) aur 2.6 to 6.0 mg/dL (women) hota hai. Uric Acid 7.0 mg/dL se upar jane par joints me crystals jama hote hain jisse severe pain aur sujan hoti hai jise Gout (Gathiya) kehte hain, aur Kidney Stones ka khatra badh jata hai.
Serum Potassium (K+) high ya low hone par kya risk hota hai?
Normal Serum Potassium 3.5 to 5.0 mEq/L hota hai. Potassium 5.5 se zyada (Hyperkalemia) ya 3.0 se kam (Hypokalemia) hone par dil ki dhadkan aniyamit (Arrhythmia) ho sakti hai jo life-threatening ho sakti hai. Isliye KFT me electrolyte balance check karna zaroori hai.
Creatinine kam karne ke liye kya gharelu aur medical steps lene chahiye?
Painkillers (NSAIDs jaise Ibuprofen/Diclofenac) poori tarah band karein, Blood Pressure ko 120/80 mmHg par control karein, Blood Sugar manage karein, daily adequate paani piyein, aur Nephrologist se milkar ACEi/ARB ya SGLT2 inhibitors jaisi kidney-protective dawaon par consult karein.
