HIV antibody test

The HIV antibody test are the most suitable test for proper diagnosis of HIV among adults. Antibody test are affordable and incredibly correct. The ELISA antibody test (enzyme-linked immunoabsorbent) also referred to as EIA (enzyme immunoassay) was the initial HIV test being widespread.

Just how do antibody tests deliver the results?

When an individual have been infected with HIV, their entire body reacts by generating unique proteins that battles the infection, known as antibodies. A HIV antibody test searches for these antibodies in blood, saliva or urine. If antibodies to HIV are discovered, it indicates that an individual have contracted HIV. There are only two exceptions for this rule:

Infants given birth Schnelltest auf SARS-CoV2- Antigene / Bürgertest to a HIV infected mother retain their mother's antibodies for approximately eighteen months, which suggests they will test positive upon a HIV antibody test, even if they are in fact HIV negative. Generally infants who're born to HIV positive mothers obtain a PCR test (see below) after birth.

Some individuals who have taken part in HIV vaccine studies might have HIV antibodies even if they're not have contracted the virus.

A number of people produce noticeable HIV antibodies within 6 to 12 weeks after exposed to the HIV virus. In extremely unusual cases, their can be a 6 months period, and there are almost always very specific causes of antibodies developing so late for instance other auto-immune conditions. It's extremely unlikely that somebody would take more time than Six months in order to develop antibodies.

A window period of 3 month?

The 'window period' is actually a term used to explain the time period between HIV infection and the production of antibodies. During this period, an antibody test can provide a 'false negative' end result, meaning the test is going to be negative, despite the fact that an individual have contracted HIV. To prevent incorrect negative results, a second test are suggested after 3 months of possible contact with a HIV infected person..

A negative test at 3 months will more often than not, suggest that an individual have not been infected with HIV. Somebody who is tested and continues to be negative after 6 months, and have not been at risk of HIV infection in the meantime, means they are not infected with HIV.

It is extremely important to notice that if an individual is infected with HIV, they could still transmit the virus to others throughout the window period.

How correct are antibody tests?

Antibody tests are absolutely accurate when it comes to detecting the existence of HIV antibodies. ELISA tests are unquestionably sensitive and therefore will detect a small amount of HIV antibody. This higher level of sensitivity however, means that their specificity (ability to separate HIV antibodies from other antibodies) is marginally reduced. There is for that reason a really modest chance that a result could come back as 'false positive'.

A false positive result implies that even though an individual might not be infected with HIV, their antibody test may come back positive. All positive test results are followed up by using a confirmatory test, for example:

A Western blot assay - One of the oldest but most precise confirmatory antibody tests. It really is complex to manage and may even generate indeterminate results if an individual carries a transitory infection with a different virus.

An indirect immunofluorescence assay - Like the Western blot, nevertheless it relies on a microscope to detect HIV antibodies.

A line immunoassay - Widely used in the European Union. Minimizes the risk of sample contamination and it is as precise as the Western Blot test.

A 2nd ELISA - In resource-poor settings with comparatively high frequency, a 2nd ELISA test are useful to verify an analysis. The 2nd test will often be a various commercial manufacturer and make use of an alternative technique of recognition to the first.

When two tests are bundled, the possibility of obtaining an incorrect result can be lower than.1%.

Rapid HIV Test

123 Rapid Home Test ( HIV-1/2)

These HIV tests use exactly the same technologies as ELISA tests, but rather then submitting the sample to the clinical for being analysed, the rapid home test generates a results within just Twenty minutes.

Rapid HIV home tests will use either a blood sample or oral fluids. They are really simple to use and don't require any laboratory facilities or professional staff.

All positive outcomes from a rapid HIV test must be followed up by using a confirmatory test, the final results usually takes from a couple of days to a few weeks.
