Adequacy should always be stated, either as "Satisfactory" or "Unsatisfactory". For estimating the number of cells, determine the following:
- The area of your field of view at high power (see the Evaluation chapter)
- The total size of the relevant area on the microscope slide.
- Look at 10 representative high power fields (HPFs) within that area, and calculate the average number of cells per high power field.
|Total number of cells = Average number of cells per HPF *||Total size of area|
Eventually you will be able to tell when most cases are adequate or inadequate without performing a detailed calculation.
Also state whether the endocervical/transformation zone is present or absent. Count an endocervical component as present if there are 10 or more endocervical or squamous metaplastic cells.
Very common findings
Main conditions to exclude or confirm
Squamous atypia, seen mainly as cells with increased nucleus/cytoplasm ratio, nuclear hyperchromasia and irregular nuclear outline.
