How can your husband's blood test for chlamydia be negative and yours positive?

Blood test for chlamydia? Was this checking past infection? Contact your health care provider to clarify this unusal mode of testing and its meaning for your health.

A normal blood test will not detect the infection. To diagnose chlamydia, you need a urine test or swab of the vagina, urethra, rectum, throat, or eye. Blood tests can look for evidence of past infection with chlamydia, but these are of no use in determining current infection and aren't used to diagnose or treat disease.
