Background: One of the basis for the diagnosis of pregnancy induced hypertension syndrome (PIHS), includes the precise evaluation of proteinuria. The gold standard for its evaluation is the collection of a 24-hour urine specimen, but because it is a slow method, other alternatives, such as semi-quantitative albuminuria have been used more frequently on our emergency rooms. Objective: To assess the diagnostic performance of semi-quantitative albuminuria and its association with proteinuria measured in a 24-hour urine specimen collection, in patients with PIHS. Methods: Retrospective study of 145 patients with clinical suspicion of PIHS who assisted to Hospital Padre Hurtado, Chile. Semi-quantitative albuminuria (categorized as 0 to 4+) and proteinuria measured in a 24-hour urine specimen collection was measured on every patient. Abnormal values of proteinuria were considered when values exceeded 0.3 g/24 hours. Composite outcomes analysis was done between albuminuria groups and positive proteinuria in 24 hrs. Results: Sensibility and specificity of semi-quantitative albuminuria was of 50% and 100%, respectively, with a PPV: 100%, NPV: 65.7%, LR+: 50 and a LR-: 0.5. Conclusion: semi-quantitative albuminuria ≥2+ shows a strong association with proteinuria ≥0.3 g/24 hours and it could be used as a fast method to assess PIHS.

Keywords : Pregnancy induced hypertension syndrome; semi-quantitative albuminuria; 24-hour urine proteinuria collection.
