New smear test could be 100% accurate BY MARK HENDERSON A REVOLUTIONARY smear test that could make cervical cancer screening virtually 100 per cent accurate has been developed by British scientists. Cambridge University researchers have found a way of pinpointing and dyeing abnormal cells in the cervix, allowing experts who scan smears to spot danger more easily. The test, details of which are published today in Proceedings of the National Academy of Sciences, could save thousands of lives, doctors said. Under the technique doctors take a conventional smear which is enhanced to make it easier to read. Antibodies are used to seek out two protein molecules that are present only in unhealthy cells. A dye is used to highlight the antibodies and the potentially cancerous cells. Early trials of the system - called the "campaign test" after the Cancer Research Campaign, which funded its development - have shown it to be 100 per cent effective at identifying abnormal smears. Present NHS screening offers 85 per cent accuracy. Clinical trials will start in America within 18 months; British patients could benefit three years later.
