Study of The Relationship Between 24-hour Urine Protein Excretion Rate and Protein/Creatinine Ratio in Random Urine Specimen of Women with Preeclampsia

Introduction. Early diagnosis and management of preeclampsia are very important to reduce fetal and maternal complications. In this study, we examined the ratio of protein to creatinine in a random urine sample and its relationship to the rate of 24-hour urine protein excretion for quick detection and prompt management of this condition in women with preeclampsia.Methods. In this descriptive-analytical cross-sectional study, 60 pregnant women with preeclampsia referred to the maternity ward of Ali Ebn-e Abitaleb hospital of Zahedan in 2019 were recruited. The 24-hour urine protein excretion and the ratio of protein to creatinine in a random urine sample were compared in these patients.Results. The results showed that there was a positive correlation between the 24-hour urinary protein excretion and the protein to creatinine ratio of the random urine sample in preeclampsia (P < .001, r = 0.515). Women with a higher 24-hour protein excretion also had a higher urinary protein to creatinine ratio.Conclusion. In general, based on the results of this study, it can be concluded that the ratio of protein to creatinine in the random urine sample has a good diagnostic efficiency in suspected preeclampsia. It is a quick alternative method for detecting suspicious proteinuria and could be used as a screening test in emergency situations.
