🧪 MDRD eGFR (IDMS)
UseWhen to use: protocols or research still specifying MDRD; teaching comparison.
StrataMap to G-stage bands with albuminuria; prefer race-free CKD-EPI 2021 clinically.
LimitsWhen not to use: changing creatinine (use KeGFR). · Pitfall: non-IDMS assay constants. · Race coefficient is protocol-dependent / often omitted now.

How it works
175 × Scr^−1.154 × Age^−0.203 × (0.742♀) × (1.212 Black).
Key points
- IDMS 175 form.
- Legacy vs CKD-EPI.
- Next: staging + ACR.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Serum creatinine | 1.2 mg/dL |
|---|---|
| Age | 60 y |
| Sex | Male |
| Black race factor (original equation) | No (1.0) |
→MDRD eGFR61.8mL/min/1.73m²
- Cue：>=60 — G1–G2 range cue if kidney damage markers absent/present respectively
| Serum creatinine | 1.2 mg/dL |
|---|---|
| Age | 60 y |
| Sex | Female |
| Black race factor (original equation) | Yes (×1.212) |
→MDRD eGFR55.5mL/min/1.73m²
- Cue：30–59 — G3 range cue

FAQ
Frequently asked questions
- Does MDRD eGFR (IDMS) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is MDRD eGFR (IDMS) calculated in practice? Can you show a worked example?
- Inputs: Serum creatinine 1.2 mg/dL, Age 60 y, Sex Male, Black race factor (original equation) No (1.0) → Result: MDRD eGFR 61.8 mL/min/1.73m²（Cue: >=60 — G1–G2 range cue if kidney damage markers absent/present respectively） Inputs: Serum creatinine 1.2 mg/dL, Age 60 y, Sex Female, Black race factor (original equation) Yes (×1.212) → Result: MDRD eGFR 55.5 mL/min/1.73m²（Cue: 30–59 — G3 range cue）
