How Accurate is the Pap Test?

"We already knew before conducting this study that the sensitivity of the Pap left a lot to be desired," Franco said in a prepared statement. "However, 55.4 percent accuracy is only slightly above chance. Flipping a coin gives you 50 percent."

"One concern about the HPV test has been a higher rate of false positives due to its superior sensitivity, but Franco's study found only a small difference between the two screening tools. He calls the increased rate a false positives, which could lead to unnecessary additional testing, a fair tradeoff for detecting far more cervical pre-cancers..."
