Comparison of three methods to detect white blood cells in semen: leukocyte esterase dipstick test, granulocyte elastase enzymeimmunoassay, and peroxidase cytochemistry.
Comparison of three methods for the detection of WBC in semen revealed a low concordance of positive test results. Among 557 semen samples, most positives were observed with the leukocyte esterase dipstick test (n = 95; 17.1%) followed by the peroxidase test (n = 51; 9.2%). There was little overlap between positives in the esterase-dipstick and the peroxidase method (29/117; 24.8%). With only 4 of 557 samples (0.7%), the PMN-elastase ELISA showed a surprisingly low incidence of positives. Because of lack of a gold standard, none of the three methods could be identified as superior. Because of its simplicity, specificity, and cost-effectiveness, the peroxidase method appeared most suited for clinical application.
