The usefulness of ;Microstix' as a diagnostic tool in urinary tract infections in general practice has been evaluated. The nitrite component detected only 53 per cent of cases of significant bacteriuria, and gave rise to a nine per cent false positive result. The culture media correctly detected 93 per cent of cases of significant bacteriuria, but this was associated with a false positive result of nine per cent.
