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.

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

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
Hiv window period is 3 to 6 months. What does that mean? That HIV will not be detected until after six months? Super confused . Tested neg at 6 months
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 moreSee 1 more doctor answer
