Re: HIV question
Having your colon removed or having chemotherapy 5 years ago has no bearing on the accuracy of HIV tests. Most of what is quoted around the net as having a possible effect on HIV test results, such as chemo, are only theoretical. Virtually everyone in the world who is infected with HIV will test positive at 8 weeks post exposure. You are not the exception. Unless your partner has sex with men or shares injection drug equipment, he is at low risk for HIV, and your risk is close to zero. Stop worrying and expect another negative.
