Comparison of test results for urine specimens^a

Abbott assay result	No. of specimens with indicated Roche assay result
	C. trachomatis positive	C. trachomatis negative	N. gonorrhoeae positiveb	N. gonorrhoeae negative
C. trachomatis positive	238	5c
C. trachomatis negative	1	208
N. gonorrhoeae positive			53	1
N. gonorrhoeae negative			0	353

^aFor C. trachomatis there was 99.6% (95% score confidence interval, 97.7% to 99.9%) positive agreement and 97.7% (94.6% to 99.0%) negative agreement. For N. gonorrhoeae there was 100% (93.2% to 100%) positive agreement and 99.7% (98.4% to 100%) negative agreement.

^bThe Roche N. gonorrhoeae test results were scored as positive in this table only if both porA and 16S rRNA real-time PCR confirmatory (LC) assays were also positive. Accordingly, 11 Roche N. gonorrhoeae-positive test results were considered false-positive results based on confirmatory LC testing and are tabulated among the Roche N. gonorrhoeae-negative test results. Forty-five female urine samples were tested only for C. trachomatis using the Roche method and are therefore not included in the N. gonorrhoeae tabulation. All were N. gonorrhoeae negative by the Abbott assay.

^cThree specimens were C. trachomatis negative by the Roche assay, and two were equivocal for C. trachomatis by the Roche assay.
