Hello, I Went To Donate Blood And I Received A

Hello, I went to donate blood and I received a letter telling me I have reactive HCV antibody screening and a reactive NAT test. What does this mean? I don't have insurance to go get more test. I had lots of dental work done the last half of last year at our dental school here in Las Vegas. I don't know how else I could have gotten it. No drug use, married and we are always together. No other sex partners. Please tell me what should my next step be? Thank you, Trish
