In the United States, about 2â3 million abnormal Pap smear results are found each year. Most abnormal results are mildly abnormal (ASC-US (typically 2â5% of Pap results) or low-grade squamous intraepithelial lesion (LSIL) (about 2% of results)), indicating HPV infection.
OK, so what happens after an abnormal Pap smear? This will depend on your situation and what your abnormal Pap smear results actually found (which we'll get to in a bit). Sometimes your doctor may just ask you to come in for a repeat Pap test now, six months from now, or in a year. For many patients, an abnormal Pap smear often leads to HPV testing.
