Term 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]
