I took my blood test about 6 weeks after last possibly exposure. I got my test results back today and the nurse said it was negative. I ask her the results and what it overall means and it she said that below .9 is negative .9-1.1 is possibly but still negative anything about 1.1 is positive. Should I get another blood test? I still have occasional tingling in genital area. the nurse said I am totally fine but when looking in to it it says that i could still be positive. Any advice?
