Measuring eGFR based on cystatin C levels may be a more accurate assessment of kidney function in older adults

sarah JonasResearch Results

A study of more than 82,000 older adults receiving outpatient measurements of estimated glomerular filtration rate (eGFR) found that measuring eGFR based on creatinine and cystatin C levels (eGFRcr-cys) was more strongly associated with adverse outcomes than measuring eGFR with only creatinine levels (eGFRcr).

Substantial discrepancies found between estimated and measured GFR

sarah JonasResearch Results

A cross sectional study found that substantial discrepancies exist between individual estimated glomerular filtration rate (eGFR) and directly measured GFR (mGFR). Laboratory reports that provide eGFR calculations should consider including the distribution of this uncertainty. According to the authors, renaming the eGFR as a population average GFR (or paGFR) merits further discussion. The findings are published in Annals of Internal Medicine.
