Different Option of HIV Testing Online

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 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. Guangdong Longsee Biomedical Co.,Ltd 

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’.
