Is urinary protein-to-creatinine ratio a reliable diagnostic indicator of proteinuria in preeclampsia?

Proteinuria is an important indicator to diagnose preeclampsia. We compared the results of urinary protein-creatinine ratio (PCR) with 24-hour urine protein excretion (UPE) in women with preeclampsia. Materials and Methods: 84 patients with preeclampsia who had undergone 24-hour urine protein measurement were included in the study. The patient with protein excretion of 500mg/24 hr was assigned as positive case proteinuria.
