Bioluminescence screening for bacteriuria

Screening for bacteriuria.

Screening for bacteriuria with Clinitec-200.

A method of testing for bacteriuria with multiple reagent strips for blood, nitrite, and leucocyte esterase was evaluated. Of 669 urine specimens tested, 267 were negative on the reagent strips and so would ordinarily be discarded, creating a reduction in the workload of culturing urine specimens of 40%. Thirteen of these were false negative results, however, which represented 10% of all the sa...

A photometric screening for significant bacteriuria.

Screening for bacteriuria: Microstix and dipslides.

The Microstix system has been tested, in parallel with dipslides, for suitability as a screening technique for the detection of bacteriuria. Results obtained using each method on 228 urine specimens were assessed by comparison with the results of quantitative counts. Dipslides had a higher sensitivity (86-7%) than Microstix. The best specificity (100%) was obtained from those results (77-6%) wh...

Comparison of the Lumac and Monolight systems for detection of bacteriuria by bioluminescence.

The development of practical and rapid methods for detection of infectious-disease-producing agents in clinical specimens is the most important current goal of clinical microbiology. Bioluminescence is a technique which is rapid and potentially sensitive enough to detect significant numbers of bacteria in urine specimens. To determine whether bioluminescence is practical and cost effective for ...
