Hi there and thank you for contacting the AIDS Vancouver Helpline.

First of all I would like to congratulate you on your negative tests results. From what you have described, your test results are reliable and can be considered conclusive.

None of the diseases and conditions mentioned in your post are immunodeficiency diseases. Additionally, immunodeficiency diseases are usually identified in during childhood and it is not something that you can live your life normally without noticing. For further clarification on specific medical conditions and their effect on your test results, we highly recommend that you communicate with your doctor and/or your testing clinic.

Chewing tobacco is also an activity that has no connection to HIV nor an effect on test results.

HIV tests are always looking for something specific in your blood. This specific thing can be either antibodies, genetic material of the virus (DNA/RNA), or antigens (markers attached to the envelope of the virus). Most advanced tests, such the 4th generation test that you have conducted, look for more than one thing at the same time. For instance, the 4th generation test looks for antibodies AND antigens. In the event that somebody has an immunodeficiency, it is their antibody system that is affected. However, antigens and the genetic material of the virus should still be detectable within and after the 3 month post exposure period.

I trust that I have answered your questions. For additional information on HIV risk and testing, you can visit our website at
