(16) evaluated kidney function markers in pregnancy, comparing 38 women with preeclampsia vs. 22 controlled pregnant women, showing that both urine and plasma cystatin C levels were significantly higher in the preeclampsia group compared to the control group, suggesting that cystatin C could be a reliable marker of kidney damage expressed by glomerular injury in preeclampsia.
