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 just had an HIV 1/2 eia antibody screen w/ reflexes. Can you explain how this test works? Are there any better tests?

I just had an HIV 1/2 eia antibody screen w/ reflexes. Can you explain how this test works? Are there any better tests?

Viral Testing: To test for many infections we look for antibodies (your body's reaction to something new or foreign). In the case of HIV infection these antibodies can take three to six months to be positive on a test. This old fashioned test is a reliable and common screening tool. But, it is not the best test if one is possibly exposed. We now send HIV genetic tests which can be positive by day 21 post expos. ...Read more

I took a HIV-1/2 Fourth Generation test and the results were reactive. Week later my HIV RNA, QL TMA came back negative. What does this mean?

I took a HIV-1/2 Fourth Generation test and the results were reactive. Week later my HIV RNA, QL TMA came back negative. What does this mean?

HIV test: A positive HIV 4th generation test and negative HIV RNA (viral load) could mean a false positive test, or an erroneus lab result. The test should be repeated in a few weeks. ...Read more

Stop testing!: You have been seriously overtested for HIV. The duo test is always positive within 4 weeks of infection. Every test after that was superfluous and a waste of money. It is past time to move on without further worry about it. ...Read more

CMIA 4th gen antibody screening test (not antigen) for hiv 1 & 2 @50 days is 0.15 non reactive. Is antibody screening without antigen accurate @7thweek?

Conclusive at 6+ wk: Official advice by many agencies is that stand-alone HIV antibody tests are not conclusive until 3 months. However, with the modern tests in current use, including the test you had, the results actually are conclusive any time 6 or more weeks after exposure. Feel free to have another test at 3 months if another negative result will help you get beyond your fears. But I really isn't necessary. ...Read more

Fourth generation HIV test detect rare subtypes or rare groups of HIV 1 and 2?

I went for HIV 1/2 & p24 Combo test (CMIA) Test on 32nd day after HIV exposure and result was non reactive. 1). How much I can trust these result?

100%: The combo (antibody-antigen) HIV tests are 100% conclusive any time 4 weeks or more after the last possible exposure. You definitely do not have HIV and don't need any further tests. ...Read more

Hiv 1/2 eia non reactive at 8 weeks and again at 23 weeks. How confident should I be that I'm HIV negative?

6 months window: Depending on the time of exposure about 6 months window for seroconversion is usually sufficient. However if exposure has significant extending testing to one year may be more reassuring. ...Read more

I went for HIV test which is HIV 1/2 & p24 Combo test (CMIA) on 32 and 41 day of my last exposure, report says non reactive. Is this 100% conclusive?

Nearly so: For a definitive answer you should get a HIV nucleic acid test done at 12 weeks after the exposure. If that is negative that will essentially rule out HIV infection. Even the combo test, if negative at 12 weeks would be strong evidence against the infection. ...Read more

Report value result is cut of index 0.553 reference range cut of index 0.90 non reactive negative for HIV 1 and HIV 2 what is meaning of 0.553 n 0.90?

Antibody Testing: This sounds like a good question. This is the way antibody testing is reported by labs when searching for viral infections.

If the antibody response is not acute enough one is not considered to be infected.

Any further testing in this case should be based upon risk and recent experience. One can also be tested by searching for the genetic material of the HIV virus instead of antibody testing. ...Read more

Hi. Tested for HIV 1/2/0 and p24 ag separately on 77th day= negative...They gave me an index of 0.449 for my p24.Is that worrisome or just non reactive?

HIV: There are several different products designed to measure the presence of p24 antigen and do not know what the parameters are since do not know what test was performed. The best measure would be to do an HIV RNA pcr, or your antibody titers will often be positive by now. ...Read more

Hi I had HIV 1&2 lab test and the results are non reactive (0.347) cutt off rate is 1.0 test performed my ECLIA, I m so worried is it higher. Please help me?

Likely negative: ELISA is highly accurate, almost 99%. So please be reassured. Repeat the test in four weeks or so to ensure it remains negative. If you have not been sick with a fever, rash, sore throat, enlarged glands, chills, night sweats etc. In the last two months, then the risk of being infected in last two months is even lower. ...Read more

What does a nonreactive/neg HIV 1/2 AG/AB 4th GEN/RFL mean? Why does it say it does not exclude HIV and that seroconversion is variable?

For the lawyers: Nobody knows how often the new HIV tests turn positive "late" because nobody really knows who's done what other risky stuff and not told about it. I'd accept negative / nonreactive results if the usual time frame for the test has lapsed, be thankful for good health, love safely from now on, and share the memory of whatever happened as something to be treasured. ...Read more

HIV: These results show that you do not have antibodies to hiv. This does not necessarily mean that you are free of disease, since it may take varying durations of time from infection to seropositivity. But these results are quite normal. ...Read more

Could one infected with both hiv-1 and hiv-2 at a time?

Yes: Infection with either hiv-1 or hiv-2 is not protective against a superimposed infection by the other virus. So in theory, yes, one could get both in one individual. Hiv-2 is fairly uncommon in the us so infection with it is unlikely. ...Read more

HIV 1&2 P24 Combo (CMIA) test done on 13th day. Index value is 0.1 and non reactive. Symptoms. White patches on tongue so far. How reliable is my test?

Pretty reliable: This test result is about 80-90% reliable in showing you did not catch HIV 13 days previously. Have another test at 4 weeks to be 100% certain. It is much too soon for "white patches" on your tongue to be due to a new HIV infection; they have nothing to do with HIV or your possible exposure to it. ...Read more

HIV 1&2 P24 combo 13th day. Index value 0.1&non-reactive. Oral Candiasis (tongue) on14th day. Is this ARS? No other symptoms so far. How reliable is test?

Very reassuring: I think this is a duplicate question, same answers. Oral candida is not likely (not the same as white coated tongue). But even if candida, it is too soon for it to be from an HIV infection caught only 2 weeks previously, and is never the only sign of ARS. Your test is about 90% conclusive that you don't have HIV. Have another combo test at 4 weeks to be certain, but in meantime really no worries. ...Read more

Conclusive, no HIV: That HIV test is conclusive. It cannot later become positive if you are not reexposed. The blood count result normal and is meaningless in regard to HIV; if HIV is your only concern, the blood count should not have been done. ...Read more
