MDRD eGFR calculator
Result
≥60 (imprecise at GFR>60)mL/min/1.73m²
G1–G2 — Use CKD-EPI for reporting
CKD-EPI 2021 preferred for clinical reporting.
How to use it
- 1
Legacy equation. MDRD underestimates GFR at values >60. CKD-EPI is more accurate across all GFR ranges.
- 2
Use when. Some laboratory reports still use MDRD. Useful for historical comparison.
- 3
Report as ≥60. MDRD is not precise above 60 mL/min.
When to use it
- Historical lab results using MDRD
- Compare trends over time.
- When CKD-EPI unavailable
- MDRD remains acceptable for GFR < 60 mL/min.
- Research databases
- Older studies used MDRD — consistent comparison.
