Description
This 4th Generation HIV Test Detects HIV With 99.80% Clinical Specificity.
After you have been exposed to HIV there is a period of time called seroconversion. During this latency period the virus reproduces and your body produces antibodies to levels that are detectable in the blood.
An HIV antibody test can detect HIV within four weeks of exposure for 95% of people and for 99.9% within 12 weeks.
The window period for detecting HIV p24 antigens is much faster. This new 4th generation HIV test reduces the detection window to as little as one to four weeks.
A negative result on a 4th generation test performed at four weeks post-exposure is highly likely to exclude HIV infection.
In some rare cases, it is possible for seroconversion to take longer. This is why the recommendation for those that receive HIV-negative test results is to be re-tested at eight weeks post exposure.
If you are at ongoing risk of HIV infection you are advised to retest every three months.
Note that home-based self-test HIV tests are very unreliable and miss about one HIV positive result in every 12 tests. You should insist on professional laboratory testing like this only.
