The Association Between GFR Evaluated by Serum Cystatin C and Proteinuria During Pregnancy.

Introduction: Physiological changes in pregnancy result in increased cardiac output and renal blood flow, with a consequential increase in proteinuria. Data from studies of the relationship between proteinuria caused by isolated proteinuria and glomerular filtration rate (GFR) are still limited. The objective of this study was to investigate the effects of isolated proteinuria on the cystatin C-based GFR in the third trimester of pregnancy.
