  • Title: Evaluation of the Bacteriuria Detection Device.
    Author: Hoyt SM, Ellner PD.
    Journal: J Clin Microbiol; 1983 Oct; 18(4):882-4. PubMed ID: 6630467.
    Abstract:
    The ability of the Bacteriuria Detection Device (BDD) (Marion Laboratories, Kansas City, Mo.) to detect significant bacteriuria was evaluated. Quantitative plating and BDD results were compared for 513 clinical specimens, 188 of which were voided. Eighty-seven specimens (17%) could not be tested because of clogging or excessive pigmentation. Specimens were considered positive if they contained more than 10(4) bacteria per ml. Thirteen specimens gave false-negative BDD results; 10 of these contained gram-positive cocci. The sensitivity of the BDD test was calculated to be 89%; the specificity, 65%. The predictive value of a negative test was 94%; that of a positive test was 49%. The efficiency of the BDD test was 71.6%. The BDD has the potential for providing rapid detection of bacteriuria, but requires further improvement before it can reliably be substituted for urine culture.
