Paranoia about HIV exposure. 4th Gen test, negative at 9th, 17th, and 37th day. RNA QL TMA early test, negative at 17th and 37th day. Can I rest easy?

Rest easy: There are 2 types of HIV tests, viral antibody tests are the most common and inexpensive. 95% of people who have contracted AIDS show positive within 90 days, but it can take 6 months. Then there are tests looking for the virus itself (viral load) these will be positive within 2 weeks or sooner. These are the early tests such as RNA QL TMA. Based on that, Be safe and relax. Good health ...Read more

Hiv (Definition)

Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more

What is the likelihood of a false negative on a PCR RNA TMA HIV test at 15-20 days post PEP/post exposure? I have heard of false positives.

What is the likelihood of a false negative on a PCR RNA TMA HIV test at 15-20 days post PEP/post exposure? I have heard of false positives.

Too soon to rule: out HIV. The PCR RNA test if negative at about 3 months after exposure would rule out infection. A negative result before than may not be definitive. A positive result be definitive any time. ...Read more

What is the accuracy of the RNA HIV test?

What is the accuracy of the RNA HIV test?

Not for diagnosis: It's very useful for monitoring the response to hiv, and it's accurate to diagnose or rule out acute HIV infection in someone with symptoms, but for simply diagnosing HIV infection, the HIV serology (antibody test) is better. That's because people who aren't infected can have false positive RNA tests, and people who are positive can have false negative RNA test. ...Read more

How long should I wait to get HIV 1 DNA RNA test?

How long should I wait to get HIV 1 DNA RNA test?

Need more info : To give an answer to your question more information is needed. Did you recently start medications to treat hiv, then the answer is after about 1-2 months. Did you recently engage in a high risk activity, such as unprotected anal intercourse? In that case, i would advise first and foremost to use protection in the future and to be tested as soon as possible. Hiv may show up as soon as 7-10 days. ...Read more
