“Who is responsible when a procedure as routine, and as life-saving, as a Pap smear shows up as a four-figure item on a patient’s medical bill? Should the doctor know the accumulated costs of all the tests that are being ordered? Are labs becoming more savvy by marketing multiple-test packages? And will the specter of sticker-shock keep women from undergoing important screenings?”
