Correlation of protein measurements in 4 and 24 hour urine samples in women with initially diagnosed preeclampsia

ABSTRACT

The aim of this study was to substitute measurement of 4 hour urinary protein instead of 24 hour urinary protein, which is the gold standard of proteinuria detection in patients with preeclampsia. This descriptive - cross sectional prospective study was conducted in two university hospitals in Zahedan in the year 2004. 38 patients who were admitted due to preeclampsia and had 1+ or more proteinuria were studied. Each patient collected two urine samples one was 4 hour urinary collection [from 8 o'clock to 12 mid day] and the other was 24 hour urinary collection [from 8 o'clock to 8 o'clock]. This study showed Pearson coefficient correlation for 4 hour urinary protein and 24 hour urinary protein was r= 0.96 [P< 0.01]. This study showed there is a direct correlation between 4 hour urinary protein and 24 hour urinary protein, and we can substitute the results of the former test for the latter
