Objective(s):To assess the diagnostic accuracy of
spot urine protein-creatinine (P/C) ratio and its compareson with 24-hour urine
proteinuria for predicting eclampsia. Method(s): Spot urine P/C ratio was determined
in a mid-stream urine sample, and the 24-hour urine protein was measured. The
correlation between the spot P/C ratio and 24-hour urine protein amount was
done. Logistic regression analysis and ROC curve analysis have been used to
analyse data. Result(s): There was a strong correlation between the spot P/C
ratio and 24-hour urine protein excretion (pearson’s correlation coefficient r
= 0.71; P < 0.0001). The optimal spot P/C ratio cutoff point was 0.25, for
300 mg/24 h of protein excretion, with sensitivity and specificity of 69% and 75% respectively. Conclusion(s): Spot
urine P/C ratio is a quick and reliable tool which can be used as an
alternative method for evaluation of
proteinuria for diagnosis of pre-eclampsia.
