When I told the doctor I wanted an HIV test, I had to sign a waiver. I havent had sex in a year. My ex boyfriend whom I was active with had tested negative for HIV last year & I havent had sex since. I just wanted to take a test to get peace of mind & even the form I had to bring to the lab had an HIV test checked off too. SO I am confused. If I had to fill out the waiver & if the lab sheet instructed the lab people to test me for HIV, then why was I given a CBC test?
