Question: What STDs does a Pap smear and Colposcopy detect?

Can these tests detect STDs such as HIV, Gonorrhea, Syphilis etc?
Thank you in advanced for answering.

User avatar Hi,
PAP smear testing and colonoscopy are not primarily used for detecting STD's. But at times, incidentally may lead to suspicion of some STD .

For example, on PAP smear study,ASCUS may be incidentally seen. ASCUS (which is an acronym for "Atypical Squamous Cells of Undetermined Significance") - which means that there are some abnormal- looking cells on the test and more tests may be needed to see if the HPV (human papillomavirus) is the cause for the changes.This, if confirmed, will lead to tests for other STD's.

There are reports of Colonoscopic biopsy specimens being analysed by DNA techniques for chlamydia pneumoniae & chlamydia trachomatis in cases of suspected IBD(inflammatory bowel disease).This no doubt,opens up many potential avenues for research.In future, other organisms also may be identified.

Thus, chance identification of one causative agent of STD's would no doubt, prompt screening of an individual for other STD's.

Let me stress again that PAP smear testing and colonoscopy are not primarily modalities used for detecting STD's.
Good day!
