LOINC description : Glomerular filtration rate (GFR) is considered the best overall index of kidney function;
however measured GFR is not practical in the routine clinical setting. Estimated glomerular
filtration rate (eGFR) is a suitable alternative and can be calculated for adults
18 years using an equation incorporating the patient's age, gender, and measured serum/plasma/blood
creatinine only (eGFRcr) [LOINC: 98979-8] or both serum/plasma/blood creatinine and
serum/plasma cystatin C (eGFRcr-cys) (this term). The serum/plasma/blood creatinine
value is based on a measurement procedure that is traceable to the isotope dilution
mass spectrometry (IDMS) reference measurement procedure for creatinine, and the serum/plasma/blood
cystatin C value is based on a measurement procedure that is traceable to the certified
reference material ERM-DA471/IFCC from the Joint Research Center of the European Commission.
The 2021 CKD-EPI equations used for eGFRcr and eGFRcr-cys do not have a race term
as does the older estimating equations that they replace.[https://www.nejm.org/doi/pdf/10.1056/NEJMoa2102953];
