Definition / general
  • Unsatisfactory if more than 75% of specimen is obscured by blood or inflammation
  • Also due to scant cellularity or if specimen is rejected not processed or unsatisfactory for evaluation due to another reason
  • An adequate conventional Pap test should have 8,000 to 12,000 squamous cells
  • An adequate liquid based preparation (LBP) should have at least 5,000 squamous cells (review at least 10 microscopic fields at 40×)
  • Examples of sample reports for unsatisfactory cases:
    • Unsatisfactory because of obscuring inflammation
    • Unsatisfactory because of insufficient squamous cellularity
    • Unsatisfactory because of obscuring blood
