Abstract

Although rapid screening of negative and inadequate cervical smears is a quality assurance requirement for all UK laboratories, there has been littleattempt to standardize the method and laboratories make use of a number ofdifferent techniques and times. The aim of this study was to assess the sensitivity of these various techniques by measuring their ability to pick out known false-negative smears. Completed questionnaires from 123 laboratories across England revealed that 52% of laboratories use a 'step' technique,19% use 'turret', 15% use random paths and 34% attempt to rescreen the whole slide quickly. Twenty-two percent of laboratories use a mixture of techniques. Timings are also variable, with the majority of laboratories allowing screeners to review slides at a pace decided by themselves but usually between 1 and 2 min. The study involved 120 participants who performed a total of 24 000 rapid screens. The results showed that, of the 90 abnormal slides used in the study, 62 cases (69%) were identified as abnormal or needingreview by more than 50% of participants. Overall rapid screening picked out 58% of high-grade squamous abnormalities, 59% of low-grade abnormalities and 72% of glandular lesions. Step screening performed best, followed by whole slide/random and then turret. One minute was the optimum time and therewas a significant fall in performance once individuals attempted to rescreen large numbers (> 50). The most significant finding was the marked variation in the performance of individuals using the same slide sets.
