Can a Pap smear detect chlamydia?

A Pap smear cannot detect chlamydia. A Pap smear is a screening test for cervical cancer and pre-cancerous conditions. Chlamydia is a sexually transmitted infection (STI) caused by the bacterium Chlamydia trachomatis. To test for chlamydia, a urine test or a swab test of the cervix, urethra, or rectum is typically used.
