Question

Does a non-reactive test after 6 months mean I am HIV negative?

25 March 2008. Related: All topics, HIV transmission.

i had sexual exposure in august 2007. i went for antibody test at the end of three month and the result was non-reactive.

i went for antibody test at the end of six month and the result was non-reactive again.

After the incident in august2007 i have not involved myself in any risky behaviour .
is this result reliable enough to consider myself hiv negative. do i need further testing?

Answer

Answer: Simon Collins

Non-reactive 6 months after exposure means that you are HIV negative.

You do not need another test.

    Hi Sa,

    A non-reactive test 2 years after exposure equals HIV negative.

    Hi Suresh,

    Most people generate HIV antibodies within 4–6 weeks, but approximately 5% of people take up to 3 months. Very rarely it can take longer. Please see this link http://i-base.info/qa/257.

    Hi Lokendra,

    Please see this link for answers to HIV testing.

    However:
    Non reactive means HIV negative.
    Any optical density number below 1.0 means HIV negative.

    This number at the end is called the Optical Density (OD) value. This is the measure of how much colour there is in the dish at the end of the ELISA.

    As the colour in the dish is an indicator of whether the result is negative or positive these numbers give the result more precisely than just a simple ‘positive’ or ‘negative’ answer.

    The cut-off values for different tests vary. In general, any numbers below 1.0 means it’s a negative result. Any numbers above 1.0 mean it’s a positive result.
