TABLE 2.

Estimates of sensitivities and specificities of SDA, PCR, TMA, and culture for detection of N. gonorrhoeae by reference standard

Standard and test	No. of infected individuals	% Sensitivity (95% CI)	No. of observations	% Specificity (95% CI)
Infected if the results of any two of three comparator tests were positive; otherwise, uninfected
SDA	59	93.2 (83.5-98.1)	902	96.3 (94.9-97.5)
PCR	66	80.3 (68.7-89.1)	895	73.0 (69.9-75.9)
TMA	67	83.6 (72.5-91.5)	894	98.6 (97.5-99.2)
Culture	76	50.0 (38.7-61.7)	885	99.4 (98.7-99.8)
Infected if the results of all three comparator tests were positive; otherwise, uninfected
SDA	35	97.1 (85.1-99.9)	926	94.2 (92.5-95.6)
PCR	37	91.9 (78.1-98.3)	924	71.8 (68.7-74.6)
TMA	34	100 (89.7-100)	927	96.2 (94.8-97.4)
Culture	52	65.4 (50.9-78.0)	909	99.0 (98.1-99.6)
