Objective : To determine whether random urinary protein-to-creatinine ratio correlated with the quantitation of 24-hour proteinuria in cases of preeclampsia.
Design : Cross-sectional descriptive study.
Subjects : Pregnant patients hospitalized in the obstetric ward, King Chulalongkorn Memorial Hospital due to preeclampsia.
Method : The random urine specimens were obtained from the eligible subjects for protein to-creatinine ratio determination, the subjects were then instructed to collect 24-hour urine samples for protein measurement.
Results : Twenty-five pregnant patients completed the study. There was a strong correlation = between the random urinary protein-to-creatinine ratio and the quantitation of 24-hour proteinuria (r 0.929, p < 0.001).
Conclusion : The presented data support a strong correlation between random urinary pro tein-to-creatinine ratio and quantitation of 24-hour proteinuria in hospitalized pregnant patients with preeclampsia.
