What other bacterial infections(non-std) can result in positive igm blood test for chlamydia trachomatis. i have not been sexually active for 7 years so had the blood test retaken - again positive but a pcr urine test came back negative.no symptoms ?

Chlamydia diagnosis: All blood tests for chlamydia are useless, whether IgM or IgG. A positive test can result from distant past infection, no longer present; from infection with related bacteria, especially Chlamydophyla pneumoniae; and IgM tests in particular can give enitrely false results. Stop having blood tests, and find a doctor who knows they don't work! Negative PCR means you are not infected at this time.
