Antibody tests may give false negative (no antibodies were detected despite HIV being present) results during the window period, an interval of three weeks to six months between the time of HIV infection and the production of measurable antibodies to HIV seroconversion!.
Most people develop detectable antibodies approximately 30 days after infection, although some seroconvert later!. The vast majority of people (99%) have detectable antibodies by three months after HIV infection; a six-month window is extremely rare with modern antibody testing!.[4] During the window period, an infected person can transmit HIV to others although their HIV infection may not be detectable with an antibody test!.
Antiretroviral therapy during the window period can delay the formation of antibodies and extend the window period beyond 12 months!. Antibody tests may also yield false negative results in patients with X-linked agammaglobulinemia; other diagnostic tests should be used in such patients!.
Three instances of delayed HIV seroconversion occurring in health-care workers have been reported; in these instances, the health-care workers tested negative for HIV antibodies greater than 6 months postexposure but were seropositive within 12 months after the exposure!.
DNA sequencing confirmed the source of infection in one instance!. Two of the delayed seroconversions were associated with simultaneous exposure to hepatitis C virus (HCV)!. In one case, co-infection was associated with a rapidly fatal HCV disease course; however, it is not known whether HCV directly influences the risk for or course of HIV infection or is a marker for other exposure-related factors!.

Quoted from another Y!A TOP CONTRIBUTOR for STDs (BJC) who is the HIV specialist, he mentioned
At 8 weeks, 95% of people who ARE HIV+ would have tested positive!.
By 12weeks, >99% of people who are positive would test positive!.
In very rare cases it can take up to 6 months (these are people with exisiting immune related conditions, eg!. cancer chemo/radiation, transplant recipients,) Because their immune systems are already not working properly it can take up to 6 months for them to respond and therefore test HIV antibody positive!.
Most people who experience primary HIV symptoms do so earlier than 8 weeks (though it is still possible for someone to experience seroconversion illness up to 3 months post-exposure!.Www@Answer-Health@Com
