Noneffect of methyldopa on urine glucose tests

Abstract

Methyldopa has been reported to cause a false-positive urine glucose test by the copper reduction method (Clinitest). We investigated the effect of methyldopa on urine glucose tests in 30 patients by comparing commonly used glucose oxidase methods to Clinitest. The results of our study indicate that methyldopa does not interfere with the copper reduction method for urine glucose determination.
