چکیده
IS THERE A ROLE FOR ROUTINE USE OF THE LEUCOCYTE ESTERASE TEST? Marrazzo et al have shown that, in a population screening strategy for chlamydia, the leucocyte esterase test on urine may reduce costs because of a reasonable negative predictive value. However, the positive predictive value of this test in asymptomatic men was only 20.1%. With a sensitivity similar to that of the smear (66.7% versus 65.3%, respectively) but an inferior specificity (76.8% versus 85.5%), an approach based on the leucocyte esterase test would in fact perform even worse than one based on smears.

متن کاملLeucocyte esterase test as rapid screen for non-gonococcal urethritis.
The two standard tests for the initial diagnosis of non-gonococcal urethritis (NGU), microscopic examination of gram stained urethral smears and the two glass urine test, have the disadvantage of being insensitive and subjective. The leucocyte esterase test detects enzymes specific to polymorphonuclear leucocytes and can therefore be used as a sensitive indicator of pyuria. This study sought to...

The study has strived to compare the leucocyte-esterase stripe activity on sputum samples with gram-stained direct smear microscopy. This is for the demonstration of white blood cells (WBCs) and so to develop a simple method for selecting suitable sputum samples for cultural examination and laboratory diagnosis. . A total of 17(34.0%) out of 50 samples studied were shown to be unsuitable fo...
