HAD protected sex one time with high risk woman. I took COMBO HIV TEST@26 DAYS AND RNA PCR @ 11 DAYS. BOTH CAME BACK NEG. DO I need retesting after 3 months? I have been having headaches, feeling disoriented, and sweating a bit. Is this anxiety?

HAD protected sex one time with high risk woman. I took COMBO HIV TEST@26 DAYS AND RNA PCR @ 11 DAYS. BOTH CAME BACK NEG. DO I need retesting after 3 months? I have been having headaches, feeling disoriented, and sweating a bit. Is this anxiety?

Yes to be certain: If you were protected that the chances of transmission should be very low. If you want to be absolutely positive you should repeat it in 3-6 months. I really cannot say about the headaches, feeling disoriented and sweating. I do not know your history. I would advise you to see your doctor ...Read more

Polymerase Chain Reaction (Definition)

Polymerase chain reaction is a method of finding a specific piece of dna and copying it over and over again until there is enough to study. The technique allows a scientist to detect very small amounts of dna in a swab sample then reproduce enough of it to study it. It is very sensisitive for detecting the presence of certain bacteria and is also used in doing other ...Read more

Given that HIV 1 RNA PCR test result undetectable 25 days after possible exposure, when and which HIV test to take next?

Given that HIV 1 RNA PCR test result undetectable 25 days after possible exposure, when and which HIV test to take next?

HIV: If you are negative by HIV RNA PCR at 25 days after exposure the chances of you becoming HIV positive are next to nil. If you really want to test yourself a combination test which includes p24 antigen and HIV antibody can be done at 3 months. Think you are going to be fine. ...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.

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 are the odds of having a faulty HIV test? This includes antigen, PCR RNA tests, and antibody tests.

What are the odds of having a faulty HIV test? This includes antigen, PCR RNA tests, and antibody tests.

HIV testing...: 4th gen HIV testing and other tests are all fairly accurate. If there are concerns they can be repeated. If negative results 6 months after concerning exposure it is highly unlikely that results are inaccurate. Talk to your doctor about results if you are concerned and always remember to limit your risks with future sexual encounters: use protection, avoid high risk scenerios ...Read more

Not for HIV: It would help to know your risk factors for acquiring HIV, but, regardless, absence if viral DNA after 4 months followed by absence of HIV antibody at 5 months means that we're 99.9% certain you haven't acquired the HIV virus. However, you need to follow up with your doctor about the swollen lymph nodes. ...Read more

Highly unlikley: But hopefully you were also tested for a host of other stds at the same time. The lesson is universal barrier protection. With mono-like illness this could be one of many other diseases, like cmv, toxoplasma, and so on. Only a detailed work-up is likely to clear this up, but then you have to ask yourself if it will make a difference in your long-term health, particularly if you are now better. ...Read more

Is a PCR RNA test for HIV the same as a nucleic acid test? A doctor has told me this is no more accurate than a DUO test after 28 days post exposure..

My lymph nodes above my adams apple and under my chin all in total about three of them, 5 HIV tests two of them RNA PCR all negative what could it be?

Enlarged node: Could be several things. Most likely reactive process due to infection. If the node persists after a round of antibiotics I would suggest an fna be performed. In this procedure a tiny needle is introduced and a small sample of cells is collected and sent to a pathologist for review. ...Read more

4 month neg HIV test brief unprotected encounter with female is this conclusive 3 2ndgenantibodies test neg three rapids neg and a PCR undetectable?

4 month neg HIV test brief unprotected encounter with female is this conclusive 3 2ndgenantibodies test neg three rapids neg and a PCR undetectable?

Probably, clarify.: The standard HIV test is first the elisa, for screening, and then the western blot for specificity. The western blot is done if the elisa test is positive. Nucleic acid tests, like pcr, are used in testing donor blood. Although the basic tests can be extermely accurate there is a chance of false negatives due to the up to 6 month seroconversion time it takes to make antibodies. See my comment. ...Read more

Should I spend more money on a 7 month FDA PCR HIV test if I have a negative one already at 4 months? I have also negative AB/AG at 1, 3, 4, 5, 6 months.

Should I spend more money on a 7 month FDA PCR HIV test if I have a negative one already at 4 months? I have also negative AB/AG at 1, 3, 4, 5, 6 months.

No, not unless...: No extra testing is needed, after a reliable negative test, unless a person is having new exposures to HIV-positive partners... but that should not happen, meaning a person must learn from his past. He should not be recurrently exposed to HIV, and should then fall under the guidelines for the general population, with regards to HIV screening for the community population. ...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

Hiv Test (Definition)

There are several ways to detect the HIV virus. The first is by antibodies. This includes eia (enzyme immuno assay). The rapid HIV tests are these types. The second way detects proteins on the viral coat (western blot). This is a gel plate electrophoresis. Thirdly there is pcr (polymerase chain reaction). This detects and amplifies dna allowing a viral ...Read more
