you have answered one guy on 25 -05 -2011 , and his question was
can a test done at 5.5 months become positive later ?

And your ans is
Any test for HIV, gives only the current status of infection, and does not predict the future changes of the test results.

But, 97% of individuals that are infected with HIV, become seropositive within 4-12 weeks of exposure.

Hence in your case, since the tests have been negative, so far, the chances for the test results to change is only 3 %

Here you have mention that chance of test result to change is 3%

When i asked same question you told me these 3 % is for those who have
following prob

1. Disorders of antibody production: Hypogammaglobulinemia ; X-linked agammaglobulinemia ; IgA deficiency ; IgG deficiency ; IgM deficiency ; Hyper IgM syndrome ; Wiskott-Aldrich syndrome • Hyper-IgE syndrome

2. Common variable immunodeficiency etc.

And people with good immune system does not need to wait till 6 months

Sir , please make it clear

Hello and welcome to e health forum.

The answer given is self explanatory.

It is certainly possible that a negative test result to change to a positive, overtime. This is the basis, why health care providers ask patients to repeat the tests at a later date, to avoid missing a infected patient.

97% of normal individuals with a good immune system, produce antibodies within 4-12 weeks and the remaining (3%) might produce the antibodies, around or after 6 months.

I have mentioned the conditions, (that you have mentioned in the query above) which in case a person has, can have delayed antibody production, and hence will require repeated testing upto 6 months or more. It is in such patients that tests can become positive at a later date.

I hope this clears your doubts.
