How this service works
IDMS 4-variable MDRD eGFR (Levey 2006) from standardized creatinine, adult age, sex, and caller-assigned Black. magent does not assign race. Deterministic published formula with citation; not CKD-EPI 2021 and not a dosing recommendation.
Output
Returns the MDRD eGFR value in mL/min/1.73m² calculated from the Levey 2006 4-variable IDMS-standardized formula, applying a 0.742 factor for female sex and 1.212 factor for caller-assigned Black race, along with the published citation. Does not produce a CKD-EPI 2021 result and is not a dosing recommendation.
Example use cases
CKD staging in clinic workflow
“My 65-year-old female patient has a standardized serum creatinine of 1.4 mg/dL and is not designated as Black — what does the MDRD formula give for her eGFR?”
Medication dosing adjustment check
“I need the MDRD eGFR for a 72-year-old male, creatinine 2.1 mg/dL, not Black, so I can check whether his renal function warrants a drug dose reduction.”
Lab result interpretation in EHR
“A 45-year-old Black female has a creatinine of 110 µmol/L on her labs — can you run the Levey 2006 MDRD equation to get her eGFR?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/mdrdWhen to prefer
Use this endpoint when you specifically need the Levey 2006 4-variable MDRD eGFR with IDMS-standardized creatinine for adult patients, particularly in legacy clinical workflows or research contexts that call for MDRD rather than CKD-EPI 2021. Prefer this over CKD-EPI when institutional protocols or historical comparisons require the MDRD formula explicitly.
Side effects
- Age out of range (not 18–120) returns validation error
- Creatinine out of range (not 0.1–20 mg/dL equivalent) returns validation error
- Neither creatinine_mg_dl nor creatinine_umol_l provided returns missing parameter error
- Invalid sex enum value returns bad request
- Payment not satisfied returns 402 Payment Required
