🌟 Kidney Function Test (KFT) – Know Your Kidneys! 🧪
Your kidneys work silently every day to keep your body balanced and toxin-free. Here's a quick overview of the Kidney Function Test (KFT) — a vital tool to check how well your kidneys are doing their job. 👇
🔬 1. Objective:
To assess kidney performance by measuring key substances in blood (and sometimes urine), helping in early diagnosis & management of kidney disorders.
💡 2. Principle:
Healthy kidneys remove waste like urea and creatinine. When function declines, these build up in the body. This test helps detect such imbalances using automated analyzers or colorimetric reactions.
🧰 3. Materials Used:
✔️ Blood sample (serum or heparin tube)
✔️ Urine sample (if needed)
✔️ Clinical chemistry analyzer & reagents
✔️ Gloves, calibrators, and lab tools
🧪 4. Procedure in Brief:
1️⃣ Collect & centrifuge samples
2️⃣ Load serum into analyzer
3️⃣ Measure:
• Urea
• Creatinine
• Uric acid
• Electrolytes (Na⁺, K⁺, Cl⁻)
4️⃣ Compare values with standard reference ranges
📊 5. Sample Result:
| Test | Value | Normal Range |
|------------------|------------|---------------------------|
| Urea | 56 mg/dL | 10–40 mg/dL |
| Creatinine | 2.1 mg/dL | 0.6–1.3 mg/dL |
| Uric Acid | 8.0 mg/dL | 3.5–7.2 mg/dL (M) |
| Sodium (Na⁺) | 138 mmol/L | 135–145 mmol/L |
| Potassium (K⁺) | 5.8 mmol/L | 3.5–5.1 mmol/L |
| Chloride (Cl⁻) | 104 mmol/L | 98–107 mmol/L |
| eGFR (optional) | 42 mL/min | >90 mL/min |
🧾 Interpretation:
High levels of urea and creatinine may suggest kidney impairment, such as AKI (Acute Kidney Injury) or CKD (Chronic Kidney Disease).
🎯 6. Why It's Important:
✅ Monitors kidney health
✅ Assesses dialysis effectiveness
✅ Detects electrolyte imbalance
✅ Screens for drug toxicity
✅ 7. Conclusion:
KFT is a must in preventive health care. Early detection = timely action = kidney protection! 🛡️
