Abstract
Objective:
To describe a method of calculating sample size if rescreening of cytologic material becomes necessary for legal or other reasons. The number of specimens to be reexamined must be large enough to provide adequate confidence in the results and small enough to minimize the cost of investigation.
Conclusion:
Except under very unusual conditions, the sample size is larger than generally thought.
