My husband recently had a physical. His Dr. sent him to have some blood work done and when he went back for his follow up the dr told him that he wanted to check his liver function. He asked my husband if he was sexually active. My husband responded with a yes. Then the dr. asked if he was monogamous. My husband said yes. Then the dr said "well I want to do a Hep. screen because some people just get it and we don't know why" Is this true?
