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

I did 4th Generation HIV test after around 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 15 weeks of an exposure. Is this 100% conclusive? Can I get back safely to my wife

Sero-conversion: The whole concept of delayed sero-conversion dates back to old & sloppy tests. PCR testing now will show virus in the blood with or without antibodies. If you need to cling to the old adages...at 6 months. 99.99% of the population will have developed antibodies after an exposure. Thus the 6 month window. I believe a colleague of mine Lyssette Cardona, MD is in Dubai. She's one of the best!!

Does getting a non-reactive result on an HIV test mean negative? Even with that result can you still be infected?

Does getting a non-reactive result on an HIV test mean negative? Even with that result can you still be infected?

Yes,: Yes, non-reactive is negative. But you need to know a little more. There are two main ways of looking for HIV infection--by looking for the body's response to the virus (antibody tests) and looking directly for the virus. In the case of antibody tests (such as elisa and western blot) it may take 6-12 weeks to become "positive" (or rarely up to 6 months), so you can be "non-reactive" shortly after catching the disease, but still be harboring it. The test for the virus itself becomes positive much earlier in an infection, but is not generally described as "non-reactive" when it is negative.

Does having non reactive HIV test 1 year after high risk exposure means im not infected with hiv? I used condom.

Likely: One year after a possible exposure, it you are negative for antibodies to hiv, you are in all likelihood not infected with hiv.

I have one red bump in my neck and I did anal sex before month and half is that mean I get hiv I did hiv test after 5 days and it was non reactive als?

I have one red bump in my neck and I did anal sex before month and half is that mean I get hiv I did hiv test after 5 days and it was non reactive als?

Not necessarily: Get a HIV nucleic acid test, if the result is negative, repeat the test in 6 months. If you intend to continue having sex with men, talk to your doctor about taking pre-exposure prophylaxis. consult this site for information: https://www.aids.gov/hiv-aids-basics/prevention/reduce-your-risk/pre-exposure-prophylaxis/index. Html

The clinic performed an antibody HIV test and it tested reactive. Does this mean I have HIV?

The clinic performed an antibody HIV test and it tested reactive. Does this mean I have HIV?

Need confirmation: When a screening test is positive, it needs to be confirmed with a second test. Sometimes, the screening test will be positive and the confirmatory test negative. If the confirmatory test is positive, then you are considered to be HIV positive.

Non reactive HIV test?

Negative: It means that is negative, in other words: you were not exposed to the HIV virus, unless you are in the "window period". It would be good to know what type of test you had to tell you more about it.

Hiv test done on exact 90 days after last exposure. Result was non-reactive. Is it conclusive?

Post PeP: No. Doing pep means you need the HIV pcr test to rule out this infection so soon after stopping pep.

I took a 5th gen Ag/Ab HIV test 39 days post possible exposure. Result was non-reactive. Am I ok?

Conclusive HIV test: "Fifth generation" for an HIV test is marketing hype -- the manufacturer calls their new test 5th gen, but it's still bacially the same as all other 4th generation tests. Results of 4th gen HIV tests are usually conclusive after 4 weeks and always by 6 weeks (42 days). But 39 days is close enough; for sure you didn't catch HIV.

I had low risk hiv exposure I was tested with rapid hiv test at 6 month mark and 2.5 year mark both non reactive is it conclusive?

Yes, conclusive: All available HIV tests, including rapid tests, usually are conclusive any time after 6-8 weeks and always by 3 months. Your results prove you did not catch HIV during that exposure.

What does non-active on HIV test mean does it mean im negative or do I have something that's not showing up? Please answer

Negative: "Non reactive" means negative. Do understand that you could still have infection. It can take up to 6 months from date of exposure to "sero convert" to show up as positive on a test. You need to practice "safer" sex with the use of condoms for any intimate contact to minimize your risk of HIV or other transmissible diseases.

Did my HIV test cmia method after 2 months 15 days came out non reactive and index 0.13 does I need furthur testing or this result is satisfactory?

Tested too soon: You did not give us the kind of test you had done, but if it was an antibody test you have tested too soon and will need to test after at least twelve to twenty-four weeks.

After sex if I was douftfull and I went for HIV test after 1 month, 3 months and after 6 months 10 days -all were non reactive (negative) am I safe?

After sex if I was douftfull and I went for HIV test after 1 month, 3 months and after 6 months 10 days -all were non reactive (negative) am I safe?

Hiv: Hiv- elisa will be negative for first six months after exposure. Therefore, checking 'hiv-pcr viral load' will be the correct option for you, to clear doubt with certainty. Good luck!

My HIV test report say Non reactive by RIT Methods are mentioned. 1) Rapid immunochromatographic test 2)ELFA Why RIT mentioned specifically in result?

My HIV test report say Non reactive by RIT Methods are mentioned. 1) Rapid immunochromatographic test 2)ELFA Why RIT mentioned specifically in result?

It is common,: Especially in HIV testing where there are several methods, to indicate which method is used. There are at least 4 generations of HIV tests....each successive generation provides more accuracy and earlier definitive results. The two methods mentioned in your question are earlier generation tests; final follow-up testing at least at 3 months after exposure, and possibly 12 months, may be recommended
