I've had many hiv tests over the past few months(unprotected vaginal sex with confirmed hiv sexworker). all have been negative. just had cd4 test and count was 612 and cd8 was 645. isn't it bad when you have a ratio of below 1??? i'm freaking out!!!?

There was no reason for CD4/CD8 testing, which is not a test for HIV infection; it says nothing about HIV status. In people with HIV, CD counts are a measure of immune system function. You do not have HIV, as proved by your HIV blood test. There is nothing abnormal about your ratio. I'm sure it was upsetting to know a partner had HIV, but you definitely do not. Stop worrying and stop testing.

If a 4th gen HIV or HIV nucleic acid test was negative at three months after exposure, you did not get HIV from that exposure, Visit this site for info: HIV test window periods https://www.cdc.gov/hiv/basics/hiv-testing/test-types.html
