How are genital warts diagnosed?

Your healthcare provider can diagnose external genital warts by looking at them. Internal warts are more challenging to diagnose. You may get these tests:

  • Pelvic exam: A woman may get a Pap test as part of a pelvic exam to check for cervical changes caused by genital warts. Your provider may also perform a colposcopy to examine and biopsy the vagina and cervix.
  • Blood tests: Your provider may test for other STDs often associated with genital warts. These STDs include gonorrhea, syphilis and chlamydia.
  • Anal exam: Your provider uses a device called an anoscope to look inside the anus for warts.
  • Biopsy: Your provider may perform a biopsy (cutting out and removing a tiny piece, about the size of the tip of a pencil) when in doubt about diagnosis.
