New techniques can better detect cervical problems.
WebMD Feature Women have been going to their gynecologists for Pap tests for more than 50 years. And their vigilance has paid off: Mortality rates from cervical cancer have dropped 70%, according to the American College of Obstetricians and Gynecologists. But a woman's chance of getting a false negative -- a result that says she's healthy when she really has cancer or pre-cancerous cells -- is still between 10 and 25%, according to the ACOG.
Hoping to improve those odds, manufacturers have introduced several new methods that have been approved by the Food and Drug Administration (FDA). These new methods -- whose brand names include Papnet, Autopap and ThinPrep -- use computers to help analyze slides.
Luis Galup, a pathologist at the South Bend Medical Foundation in South Bend, Ind., is a strong advocate of the ThinPrep system. Instead of smudging a slide with cells scraped from a woman's cervix -- the conventional method -- the cells are swirled into a tube filled with a preservative and sent to a lab. In the lab, technicians filter out the blood, mucus, and other debris. A random sample of the fluid is then placed onto a slide.
