Estimation of Urinary Calcium as a Predictor of Pregnancy Induced Hypertension

Abstract

Hypertensive diseases are still a leading cause of death among mothers all over the world. It’s complicated aetiology, which begins with aberrant placentation and ends with endothelial dysfunction, is yet unknown. The goal of this study is to learn about changes in serum and urine calcium levels in women who have Gestational Hypertension. 200 normotensive pregnant women between 24-28 weeks were included in the study based on inclusion and exclusion criteria. Urine calcium and creatinine and serum uric acid, total protein, albumin and serum sodium were estimated in corresponding samples collected from patients. The study showed a sensitivity of 80%, specificity of 71%, positive predictive value was 77%, negative predictive value 74%, and diagnostic accuracy as 74%. A single estimation of calcium to creatinine ratio in asymptomatic pregnant women between 24-28 week of gestation is a simple and cost-effective test.
