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

Some people have a long HIV window period. Why is that?

Unique immune system: Every person has a unique immune system. Factors such as genetics, nutrition, and other infections (such as other genital infections and other systemic diseases) can impact the 'window' period when the person is asymptomatic. In addition, there are many different strains of hiv, some of which are associated more aggressive behavior than others. Each person's response is unique. ...Read more

What are factors that change the HIV window period from 3 to 6 months?

Misunderstanding: Hiv has no window. An exposed individual will experience infection fully within fourteen to twenty one days after exposure. A good HIV viral test will be 100% accurate in diagnosing this infection from that point forward. Antibody testing is slower detecting infection because the human body creates these HIV antibodies slowly. 95% of them, however should be diagnosable at 12 weeks, 100% by 24. ...Read more

HIV window period : Most people develop HIV antibodies within 2-8 weeks of their infection. The average is 25 days. 97% of people will develop detectable antibodies in the first 3 months. Rarely, it can take up to 6 months to develop antibody. If there's concern about acute hiv, a test that measures HIV RNA viral load can be done. The time between HIV infection and RNA detection is estimated 9–11 days. Talk with md. ...Read more

The window is open..: Current HIV tests are very sensitive & very specific [a (+) is a true (+) & a (-) is a true (-)]. Routine HIV tests check your immune systems response to the infection (production of anti-hiv-antibodies). This response (window) can take between 3 & 6 wks. False (+) may be from pregnancy, flu vaccine, auto-immune diseases). If risky behavior (unprotected sex, idu, cocaine) : test early & often! ...Read more
