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

Iran J Kidney Dis. 2023 Jul;17(4):184-190.

Abstract

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. DOI: 10.52547/ijkd.7457.
