  1. ASC-US - Atypical squamous cells of undetermined significance.
  2. ATY - Atypical Glandular Cells/NOS; Atypical Endometrial Cells/NOS; Atypical Endocervical Cells/NOS
  3. LSIL - Low-grade squamous intraepithelial lesion
  4. ASC-H - Atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion.
  5. HSIL - High-grade squamous intraepithelial lesion (moderate, severe dysplasia, Ca in situ)
