Evaluation of the MS-2 urine screening method for detection of bacteriuria.
A collaborative evaluation of the MS-2 urine screening system indicated that the automated method could successfully identify at least 84% of urine specimens that contained greater than or equal to 10(5) colony-forming units per ml. Most specimens not detected as positive by the system contained primarily diphtheroids and yeasts. Excluding those specimens which contained diphtheroids and yeasts, the MS-2 system correctly identified as positive 94.8% of specimens that contained greater than or equal to 10(5) colony-forming units per ml and as negative 96.1% of specimens that contained less than 10(4) colony-forming units per ml. The automated system is an attractive method for the screening of urine specimens for significant bacteriuria.
