URINARY ALBUMIN TO CREATININE RATIO AS A PREDICTOR OF PRECLAMPSIA AMONG PREGNANT WOMEN AT A TERTIARY CARE HOSPITAL

Abstract

Objective: To determine the diagnostic accuracy of point urinary albumin to creatinine ratio at 20⁺⁰ and 28⁺⁰ weeks of gestation for predicting the possibility of developing pre-eclampsia, late in pregnancy.

Study Design: A prospective cross sectional study.

Place and Duration of Study: Gynecology Outpatients Department of Nishtar Hospital, Multan from January 10, 2018 to January 10, 2019.

Methodology: Age, weight, gravidity and Body Mass index was documented for total 250 patients included for study. Patients were divided on the basis of development of pre-eclampsia and their mean Albumin to creatinine ratio was compared by applying Student’s t-test considering p≤0.05 statistically significant. Test positive and test negative patients were noted. The association of urinary albumin to creatinine ratio with pre-eclampsia was calculated. SPSS v.23 software was used to analyze the data.

Results: Mean urinary albumin to creatinine ratio was 22.77±12.42 mg/mmol in normotensive women and 46.87±15.13 mg/mmol in pre-eclamptic women which was significantly higher in pre-eclamptic patients (p<0.001). The sensitivity of point urinary albumin to creatinine ratio at a cutoff value of 35.5mg/mmol is 73.91%; the specificity is 91.56%; the positive predictive value (PPV) is 72.34%; and negative predictive is 92.16%.

Conclusion: Our study concluded that solitary point urinary albumin creatinine ratio values equal to or higher than 35.5mg/mmol, when quantified early during the second trimester had a higher specificity than the sensitivity and it can be safely used to rule out the possibility of developing pre-eclampsia, late in pregnancy.
