Rapid rescreening of cervical smears by cytopathologists: experience at a WHO collaborating centre for research in cytology.

The conventional 10% random full rescreening of cervical smears has been criticized as a quality assurance measure as it is not scientifically based and tends to detect only a few false negative cases. Rapid rescreening (RR) of negative cervical smears seems to be a viable alternative, especially in developing countries, as it picks up more positive lesions, reduces the false negative rate and is cost effective. We performed rapid review on 12374 cervical smears received under a hospital based cervical cancer screening programme. An additional 498 lesions were picked up on RR including a sizeable number of low and high grade lesions as well as 2 malignant cases. Thus RR led to an increase in efficiency of our laboratory.
