Methodology: In this Cross sectional study conducted at, Unit III, Department of Obstetrics & Gynecology, Fatima Memorial Hospital Lahore during the year 2019.

Results: According to urine dipstick test preeclampsia was diagnosed in 63(63%) women. According to 24 hours urinary protein criteria preeclampsia was diagnosed in 54(54%) women. Sensitivity and specificity of urine dipstick test was 90.74% and 69.5%. While PPV &NPV were 77.78% and 86.49% respectively. Diagnostic accuracy of urine dipstick was 81%.
