INTRODUCTION

Preeclampsia, a multisystemic, multifactorial disorder, is the second leading cause of maternal deaths in the Philippines. It is diagnosed by the presence of hypertension and proteinuria or significant end-organ damage in a parturient carrying at least 20 weeks age of gestation. Proteinuria, in preeclampsia, is diagnosed by having 300 mg protein in a 24-h urine sample, a 0.3 mg/mg urine protein:creatinine ratio, or 2+ protein on a urine dipstick. All currently available diagnostic tests have their advantages and disadvantages. A novel diagnostic test, the spot ratiometric urine protein:creatinine dipstick test kit, was developed to meet the limitations of the currently available methods. Early diagnosis of preeclampsia will help in the prompt management to decrease maternal and neonatal complications.

OBJECTIVES

The objective of this study was to compare the diagnostic accuracy of the spot ratiometric urine protein:creatinine dipstick test (SUPCR) in comparison to 24-h urine protein (24HUP) in the diagnosis of preeclampsia.

MATERIALS AND METHODS

A non-experimental cross-sectional study comparing spot ratiometric urine protein:creatinine dipstick test (SUPCR) to 24HUP and urine dipstick among parturients with elevated blood pressure in a tertiary hospital to diagnose preeclampsia.

RESULTS

A total of 190 parturients were included. SUPCR showed a sensitivity of 88.36%, a specificity of 93.18%, and a likelihood ratio (LR) of 12.96. Urine dipstick (2+) showed a sensitivity of 26.03%, a specificity of 95.45%, and an LR of 5.73.

CONCLUSIONS

SUPCR can be an alternative to 24HUP in detecting preeclampsia among pregnant patients due to its high sensitivity, specificity, and LR values. This novel diagnostic can be used in low-resource settings due to its fast results, low cost, and ease of use.
