This is a protocol for a Cochrane Review (Diagnostic test accuracy). The objectives are as follows:

To compare the diagnostic accuracy (sensitivity and specificity) of the Chlamydia antibody titer test and of hysterosalpingography in diagnosing tubal pathology verified by laparoscopy in subfertile women, by using studies with a paired design (i.e. CAT and HSG testing in the same patient population, the results of which have been verified in all women with laparoscopy).
