LOINC Code


LOINC code48642-3
nameGlomerular filtration rate/1.73 sq M.predicted among non-blacks [Volume Rate/Area] in Serum, Plasma or Blood by Creatinine-based formula (MDRD)
statusACTIVE

Fully-Specified Name

componentGlomerular filtration rate/1.73 sq M.predicted.non black
propertyArVRat  =  Volume Rate/Area
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemSer/Plas/Bld
    Ser  =  Serum
    Plas  =  Plasma
    Bld  =  Whole blood
scaleQn  =  Quantitative:  The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256
methodCreatinine-based formula (MDRD)

Associated Observations

LOINC codes that represent optional associated observation(s) for a clinical observation or laboratory test. A LOINC term may represent a single associated observation or panel containing several associated observations.

History/Usage

test rank50 of 2000 most commonly performed tests by labs in USA
first released
last updated2.73
last change typeMIN  - change to field other than name
change reasonSystem changed from "Ser/Plas" to "Ser/Plas/Bld". 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.
