Testing for chlamydia antibodies is
not the mainstay diagnostic tool for
chlamydia infection, which is preferentially diagnosed by
nucleic acid amplification tests (NAAT) such as
polymerase chain reaction (PCR). However, testing for chlamydia antibodies is a cost-effective screening device in detecting
fallopian tube pathology, as it is often related to chlamydia infection. The preferred technique for this purpose is by
micro-immunofluorescence (MIF), because it is superior in the assessment of tubal pathology when compared with
immunofluorescence (IF) or
enzyme-linked immunosorbent assay (ELISA). ==References==
