Q

Function of urine dipstick at first prenatal visit vs urine and culture

A

Do both, the dipstick has low sensitivty but can help screen for presence of protein, blood, or glucosuria, hwile clean catch culture and sensitivity has high accuracy and if negative risk of subsequent UTI is low but if positive then needs close follow up
