Abstract: | We present the results of 3 years' experience of rapid pre-screening in cervical cytology. In our laboratory we rapidly pre-screen all smears. The performance of each primary screener can be assessed. In addition, the relative sensitivity and specificity of each rapid pre-screener can itself be continuously monitored using the final report as a yardstick. In our laboratory individual sensitivity of rapid pre-screening for the detection of high-grade abnormalities was in the range of 44-90% with an overall laboratory sensitivity of 69%. Specificity was in the range of 94-99% with an overall laboratory specificity of 98%. Rapid pre-screening allows checking of the checkers and pathologists and tends to promote uniformity in the assessment of smear adequacy. This form of continuous quality assurance is practical, convenient and acceptable to staff. |
