76633-7Glomerular filtration rate/1.73 sq M.predicted by Creatinine-based formula (MDRD) in BloodDiscouraged

Status Information

Status
Discouraged
Comment
This term is discouraged because according to the National Kidney Disease Education Program (NKDEP) Lab Working Group, estimated GFR may be calculated based on blood, serum, or plasma creatinine levels. Whole blood methods are calibrated to be the same as serum/plasma methods, and the isotope dilution mass spectrometry (IDMS) reference measurement procedure is the same for whole blood, serum, and plasma. Therefore, this term is discouraged and mapped to the Ser/Plas/Bld term.

77147-7 Glomerular filtration rate/1.73 sq M.predicted [Volume Rate/Area] in Serum, Plasma or Blood by Creatinine-based formula (MDRD) Glomerular filtration rate/1.73 sq M.predicted [Volume Rate/Area] in Serum, Plasma or Blood by Creatinine-based formula (MDRD)

Term Description

This term was created for, but not limited in use to, the Piccolo test kit which uses a method for creatinine traceable to the IDMS reference method for creatinine, so that the following form of the MDRD equation for calculating the eGFR can be used:
GFR (mL/min/1.73 m2) = 175 x (Scr)-1.154 x (Age)-0.203 x (0.742 if female) x (1.212 if African American).
