NOTE: Restricted to histopathological outcome year 2025 from cervix (T83).
This is information for laboratory quality assurance (audit), which seeks out and after reviewing the previous cytological samples from women who later received a dysplasia or cancer. The screening is based on repetitive samples within the given range. The percentages indicate how many cases of dysplasia or cancer 'missed' by screening, but the proportion of women with dysplasia or cancer some time during the last screening interval had a Pap smear that could be included in an audit.
