3053283 - Glomerular filtration rate/1.73 sq M.predicted among blacks [Volume Rate/Area] in Serum, Plasma or Blood by Creatinine-based formula (MDRD)

Glomerular filtration rate (GFR) is a test used to check how well the kidneys are working. Specifically, it estimates how much blood passes through the glomeruli each minute. Glomeruli are the tiny filters in the kidneys that filter waste from the blood. 1

8795

In the OMOP vocabulary 8795 is a Standard Concept that represents the unit milliliter per minute (mL/min)

Plausible Low Value

6

Plausible High Value

240.00

Rationale

According to the National Kidney Foundation, values less than 15 mL/min indicate kidney failure, while values well over 100 indicate normal kidney function (depending on age) 2. Values as low as 5 mL/min 3 have been observed in the literature as well. For blacks, the MDRD equation includeds a multiplier of 1.2, so we take the limits of 5 and 200 for 3049187 and multiply by 1.2. The literature, combined with a data-driven approach to empirically establish possible low and high values, leads us to choose 6 and 240.
