Welcome to e health forum.

Window period is the time from the suspected exposure (which may have resulted in the infection) - to - the appearance of the antibodies in the serum which can be detected by serology tests (like ELISA). In layman terms, it is the waiting period for any exposed individual, who has to wait such a time, before getting tested for the condition.

In case of HIV, antibodies present only after 4 -6 weeks in about 90% individuals, and almost 95 - 99% of infected individuals produce the antibodies within 12 weeks of exposure. Hence testing for HIV is recommended at a interval of 4 weeks, at least upto 12 weeks (3 months). But repeat testing at 6 months is still recommended by CDC and WHO (specifically in extremely high risk individuals) to confirm the absence of HIV infection.

The Tri-Dot test is a rapid HIV antibody test that is very accurate and sensitive at detecting HIV infection. Getting a negative result means that you are HIV-negative.

The sensitivity and specificity of the TRI-DOT test were 99.48% and 99.99%, respectively, compared with the fourth-generation ELISA test. This means that the tests are very reliable and trust worthy especially if they are done after 12 weeks of exposure.

If you have any doubts you can consult a doctor experienced in HIV treatment to clear your doubts.

I hope this helps.
