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. | |||

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.<ref name="CibasDucatman">{{cite book | last=Cibas | first=Edmund S. | last2=Ducatman | first2=Barbara S. | title=Cytology : diagnostic principles and clinical correlates | publication-place=Philadelphia, PA | date=2021 | isbn=978-0-323-63637-7 | oclc=1138033641 | page=9}}</ref> | Also state whether the endocervical/transformation zone is present or absent.
