Watch Dr. Jitesh Jeswani explain the clinical symptoms, kidney biopsy diagnosis, and treatment protocols in this educational briefing. Read the full doctor-verified English guide below.
Glomerular Filtration Rate (GFR) represents the total volume of blood filtered by the kidney glomeruli per minute (normal: 90 to 120 mL/min). Estimated GFR (eGFR) is calculated based on Serum Creatinine, age, and gender.
Key Clinical Takeaways:
- eGFR >90 mL/min is normal; eGFR 60–89 indicates mild decline; eGFR <15 indicates kidney failure.
- Creatinine levels alone can be misleading without calculating eGFR.
- Annual eGFR checks are recommended for all adults with diabetes or hypertension.

Questions & Answers
Can low GFR be improved?
If low GFR is caused by dehydration or infection (AKI), it can recover completely. In chronic CKD, treatment stabilizes GFR.
