Abstract

A leukocyte esterase/nitrite (Chemstrip LNTM) and a bioluminescence assay (LumacTM) were evaluated for detection of bacteriuria in 1,000 urine specimens. Both devices provided high predictive negative values (95.4-97.8%); however, false-negative values at levels of bacteriuria greater than or equal to 10(4) CFU/ml were 22.6% and 12.3%, respectively, for the leukocyte esterase/nitrate and the bioluminescence assay tests. The corresponding false-negative values at levels of bacteriuria of greater than or equal to 10(5) CFU/ml were 16.5% and 3.9%, respectively.

摘要

对1000份尿液标本，评估了白细胞酯酶/亚硝酸盐（Chemstrip LNTM）和生物发光检测法（LumacTM）用于检测菌尿症的情况。两种检测设备均具有较高的预测阴性值（95.4 - 97.8%）；然而，对于白细胞酯酶/硝酸盐检测和生物发光检测，当菌尿水平大于或等于10(4) CFU/ml时，假阴性值分别为22.6%和12.3%。当菌尿水平大于或等于10(5) CFU/ml时，相应的假阴性值分别为16.5%和3.9%。
