Serum cystatin C levels are influenced by factors other than glomerular filtration rate (GFR), a retrospective analysis suggests. Serum concentration of cystatin C has been proposed as a more ...

Plasma clearance of technetium-99m-labeled diethyltriaminepentaacetic acid (DTPA) was used as an indicator of baseline GFR and, after intravenous infusion of 10% mixed amino acids, stimulated GFR.

We compared the levels of serum biomarkers for inflammation and oxidative stress between subjects with normal and mildly reduced glomerular filtration rate (GFR). Results: As compared with ...
