some questions
hi some quick questions:
1) if I am negative at 90 days do I need to test again?
2) At 90 days should I get an antibody test or an HIV DNA PCR test. If not the pcr test then why?
3) How accurate is the test at 90 days?
4) Does any medicine or medical condition delay development of antibodies?
Mine is one time unprotected encounter.
Thanks guys.

Yes a standard rapid is always the way to go for regular screening. All those other expensive tests arent needed.
so is hiv pcr dna test a waste of money at 90 days? and I guess I should just go with standard rapid test?
I agree with you that 97% is way too low also. I just repeated the CDC.
If you test negative at 13 weeks then you are negative, no question about that.
If you test negative at 13 weeks then you are negative, no question about that.
That 97% is the CDC extreamly ultra conservative approach since in some places they are still using 1st generation test, and the CDC is mixing their 80s results with today results to come up with that porcentage, the real accurateness of a test at 3 months is 99,5% accurate. dont believe that 97% CDC ********, here is a good explanation of that from Dr. McGowagan
HIV antibody tests (ELISA) will usually be reactive (positive) by 3 months after exposure to the virus (in 99.5% of cases). All positive ELISA tests are confirmed with a second antibody test called a Western Blot. Falsely negative screening tests are, therefore extremely rare. Using HIV RNA (or a "viral load" test) to diagnose HIV is not generally recommended, but can be done if someone has very recently been exposed and may have symptoms of acute HIV infection. They may be in the "window period" in the first weeks after infection when the body may not have had time to develop antibodies to HIV. The HIV viral load test may be done in cases, such as pregnant women, when it is very important to know right away that a person is infected so that decisions about treatment to prevent transmission from mother to child would be critical. Usually the viral load is very high in the earliest weeks of the infection. Since you have had both negative antibody and viral load tests this is reassuring. The antibody tests currently used are designed to detect HIV type 1 and most will also detect HIV type 2. It would be important to check with your medical provider to be sure you were also screened for HIV type 2. HIV-2 would not be detected by the viral load tests. The ELISA tests are very sensitive for detecting antibody against HIV type 1, Group M, which accounts for the vast majority of all infections in the United States.

1.Nope.
2. At 90 days a standard antibody test is all that is needed. PCR is not approved for regular screening anyway and has a high false positive rate.
3. 97% of positive people will be detected at 3 months.
4. Immune disorders, cancer patients, and other similiar serious disorders.

1) NO more test needed
2) Antibody ELISA or rapid test. the PCR is not intended for routine screnning, it have a 8% false positive rate. and other technical issues, and its very expensive
3)Its conclusive
4) only rare imumono diseases, antirejection transplant drugs and chemo.
Then go get your negative rapid 20min test, and forget about hiv.
Good luck

Frequency of HIV testing depends on your risk.
Post-exposure prophylaxis (PEP) may help prevent HIV infection.
