a
Specimens positive by the Chlamydiazyme EIA confirmed with chlamydia blocking reagent.
b
Values in parentheses are number of positive specimens/number of specimens tested.
c
Specimens positive by LCR by the LCx Chlamydia assay as confirmed by the presence of three or more EBs by fluorescent-antibody staining.
