Sensitivity and Specificity of Urinary Dipstick in Emergency Departments

Proteinuria

urinary dipstick, emergency department

Urinary dipsticks are commonly used in emergency departments since they are a cheap and quick diagnostic tool. However the sensitivity and specificity of urinary dipsticks might be compromised in emergency departments due to fluid imbalance and acute illness itself.

The study is designed as a prospective observational study on the emergency department in Sonderborg, Southern Denmark. All patients above 18 years of age who have given their consent are included. Urinary dipstick and albumin creatinine ratio is obtained simultaneously within 48 hours after admission on the emergency department. Patient with a positive urinary dipstick will be asked to deliver another urinary dipstick and albumin creatinine ratio 3-8 weeks later. To our knowledge has the specificity and sensitivity of urinary dipstick for protein not been described, yet. Our design will give us the possibility not only to quantify specificity and sensitivity in the acute phase on the emergency department but in the non-acute phase after discharge from the emergency department, as well.
