Batch screening method for detection of bacteriuria.

A mechanised batch screening method for the detection of bacteriuria.

In the modem hospital microbiology department, it is not feasible to investigate fully all routine urine specimens for the detection of bacterial infection of the urinary tract. Although increased numbers of leucocytes in the urine may enable selection of urines for comprehensive culture techniques, including direct antibiotic sensitivity testing, it is totally unacceptable to reject any specim...

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...

Leucocyte esterase - nitrite screening method for pyuria and bacteriuria EGL

The value of the one minute leucocyte esterase-nitrite chemical strips as a screening procedure for detecting appreciable levels of pyuria and bacteriuria was assessed by comparison with microscopy and culture results. The likelihood that a negative leucocyte esterase result indicated < 10 white cells/cu mm by microscopy (the negative predictive value), was 90 1% and that a negative nitrite res...
