Evaluation of a nitrite test kit (Stat-test) for the detection of significant bacteriuria.

چکیده

A commercially marketed nitrite test kit (Stat-test) for the rapid detection of significant bacteriuria has been evaluated and found to have failed to detect 50% of all cases of significant bacteriuria and 46% of significant bacteriuria associated with nitrate-reducing organisms. The number of false positive results are negligible. The Stat-test, used in its present form, cannot be recommended as a satisfactory screening test for significant bacteriuria.

Evaluation of a new sensitive nitrite test as a reliable screening tool for bacteriuria.

A new sensitive nitrite test, the SRN test, was evaluated for its suitability as a reliable screening technique for the detection of bacteriuria. The SRN test was compared to a currently available nitrite test, the Microstix nitrite test, and the results obtained with both nitrite tests were assessed in comparison with the results of the quantitative culture method. Of 158 cases of significant ...

Evaluation of the leukocyte esterase and nitrite urine dipstick screening tests for detection of bacteriuria in women with suspected uncomplicated urinary tract infections.

A positive dipstick urinalysis (i.e., leukocyte esterase test and/or nitrite test) did not reliably detect significant bacteriuria in 479 ambulatory women with suspected uncomplicated urinary tract infection; 18.9% of the urine samples that demonstrated significant bacteriuria would have been rejected by the laboratory based on a negative urinalysis screen.

Evaluation of dipstrips, direct gram stain and pyuria as screening tests for the detection of bacteriuria.

Two hundred and fifty cases of clinically suspected urinary tract infection were analysed for the detection of bacteriuria. Parameters studied included direct Gram staining, pyuria on microscopic examination of uncentrifuged urine and dip strip method for the detection of blood, protein, nitrite and leucocyte esterase. Significant bacteriuria (colony count 10(5) per ml) was found in 112 cases w...

Mass detection of bacteriuria by combination of two screening tests.

The Uriglox screening test was compared with the modified Griess Nitrite test and with standard urine cultures in the detection of significant bacteriuria on 400 ambulant and asymptomatic residents of the Athens Home for the Aged. The modified Nitrite test alone detected 62 %, and the Uriglox test 79 of the 103 cases with positive urine cultures in the examined group. There was significant over...

Laboratory evaluation of leukocyte esterase and nitrite tests for the detection of bacteriuria.

We compared the sensitivity, specificity, and predictive values of the 1-min leukocyte esterase test and the test for urinary nitrite alone and in combination as screening tests for bacteriuria in over 5,000 clinical urine specimens. The leukocyte esterase-nitrite combination had a sensitivity of 79.2%, a specificity of 81%, and a negative predictive value of a negative test of 94.5% for specim...
