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

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.
