Evaluation of six screening methods for detecting significant bacteriuria.

Evaluation of six screening methods for detecting significant bacteriuria.

Six screening methods for the successful detection of significant bacteriuria--electrical impedance (Malthus), automated acridine-orange staining (Autotrak), particle counting (Ramus), bioluminescence, nitrite and leucocyte test strip (BM Nephur), and microscopy--were evaluated. All had excellent predictive values for a negative result (97%-100%) but were less accurate in predicting a positive ...

A photometric screening for significant bacteriuria.

Evaluation of Malthus 128H microbiological growth analyser for detecting significant bacteriuria.

In a pilot study a prototype Malthus 128H microbiological growth analyser was used to study the growth of six commonly encountered urinary pathogens in a range of five different laboratory media. No single medium had been able to show acceptable conductance changes for all bacteria within five hours. Subsequently, the Malthus system, with fastidious anaerobe broth as the culture medium, was use...

Analysis of the disagreement between automated bioluminescence-based and culture methods for detecting significant bacteriuria, with proposals for standardizing evaluations of bacteriuria detection methods.

A fully automated method for detecting significant bacteriuria is described which uses firefly luciferin and luciferase to detect bacterial ATP in urine. The automated method was calibrated and evaluated, using 308 urine specimens, against two reference culture methods. We obtained a specificity of 0.79 and sensitivity of 0.75 using a quantitative pour plate reference test and a specificity of ...
