Correlation between random urinary protein-to-creatinine ratio and quantitation of 24-hour proteinuria in preeclampsia.
OBJECTIVE
To determine whether random urinary protein-to-creatinine ratio correlated with the quantitation of 24-hour proteinuria in cases of preeclampsia.


METHODS
Cross-sectional descriptive study.


METHODS
Pregnant patients hospitalized in the obstetric ward, King Chulalongkorn Memorial Hospital due to preeclampsia.


METHODS
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).


CONCLUSIONS
The presented data support a strong correlation between random urinary protein-to-creatinine ratio and quantitation of 24-hour proteinuria in hospitalized pregnant patients with preeclampsia.
