Hiv Test (Overview)

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 load to be determined.

Should I get an HIV test one week after a possible exposure?

Should I get an HIV test one week after a possible exposure?

Too soon to test: You could have taken prophylactic treatment within a day or so of the exposure. However, testing one week after exposure will not be meaningful. If the result is negative it would not rule out HIV infection. The fastest and most specific way to diagnose would be to get a HIV nucleic acid test after 3 months, if the antibody test is negative at that time. ...Read more

Can you tell me more about HIV antibody test?

Can you tell me more about HIV antibody test?

Sandwich assay...yum: Elisa = enzyme-linked immuno sorbent assay. Done by adding serum from a subject to a plate w/antibody against the infection you're testing for on its surface. The antigen (or protein) from the infection binds to the antibody on the plate. Then another antibody to the infection w/color signal chemical attached is added on top and binds to the antigen. If infection is there color can be measured. ...Read more

Sugar: I have no idea how anyone could have led you to believe you had HIV. This common situation means you need a longer treatment of the anti0-fungal medication and to take a look at how much sugar you consume in your diet and to cut out drastically nearly all sugars while you are trying to heal. ...Read more

HIV Does not hide: Absolutely not. With the routine HIV tests, which test for antibodies against hiv, if you are negative by six months you do not have hiv. With the new HIV dna or RNA viral testing if you are negative after 21 days you do not have HIV and do not need any further testing. ...Read more

6 weeks after my last sexual partner, HIV test neg. I keep getting a low grade temp and loss of appetite. What could I have, normal cbc?

Other possibilities.: There are many conditions that can cause these symptoms. Did you get a pregnancy test? If not do so. This could also be related to another type of infection which could be genital but not necessarily, for example UTI, viral syndrome, etc. If very suspicious of an STD make an appointment with your doctor for evaluation and tests. ...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!! ...Read more

Probably not: There are at least 20 different HIV blood tests in use around the world, with different cut-off values for positive results. For most or all, 1.0 is negative. Since you know the specific number, you must have a written report; it should provide that information for your test.

Are rapid hiv test effective?

Yes, but...: ...enough time must have passed since the last possible exposure. The laboratory blood tests all are conclusive within 6-8 weeks, and the 4th generation ("duo", "combo") tests at 4 weeks. The oral fluids home test takes longest of all, up to 3 months to be conclusive. So if you are concerned about a recent exposure, best to go to a doctor's office for proper counseling and testing. ...Read more

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
