How soon a hiv test be positive, after infected. how soon can it show up?

The reason the HIV test can be negative even after someone's been infected is that most HIV tests are actually looking for the antibodies people produce against the virus. How long it takes for a person to produce antibodies (and thus to give a true positive test) after infection depends on a lot of factors. Twenty-one days after infection 50% of people have produced antibodies, after three months 80% of people have produced antibodies, and after 6 months 99% of people have produced antibodies. Unless you have a strong reason to believe you've been infected, a negative test taken between 3 and 6 months after exposure is pretty solid evidence that you're negative. However, ideally you'd want to be tested again after 6 months to be absolutely sure.

It would take at least 6 months for results to show positive. After the first test you should continue every 6 months.

it take 3 months for u to get a result from a test and then if u have it u wont be noticing effects till almost a few year later. but im sure ur fine

If hurt on the job, say as a nurse, EMT etc. you are tested immediately and then 6 weeks later. If you feel it was through casual contact then you can discuss it with your doctor.

The average is 21 days, however this can vary widely. It may happen sooner in some people, longer in others. There really is no set time but just the average.

If you think you might have been exposed, have your baseline test done and then be retested at 3 months and 6 months. If you are still negative at that point, you are most likely negative. You should also be retested at 1 year post exposure.

EMT

I was tested last night after I had an exposure...stuck with a contaminated needle. The test was run STAT and I'm fine. I will be retested in 3 months.

Test now, then again in 3 and 6 months. It takes up to 3 months usually for your body to make antibodies to fight the virus.
