Thanks everyone for your kind wishes and prayers! I truly appreciate it. I feel more at ease knowing that, as many of you have said, HIV is not a death-sentence. It's hard to realize such a thing when the concept is entirely new to you or a loved one. I suppose I never imagined for this disease to affect our lives as much as it has these past couple weeks. The word "death" and "AIDS" were the first thoughts that entered my mind once my brother approached us with this topic. As frightening as these words sound, I now realize there are many precautions and measures that can be taken to ensure him a long and healthy life, thanks to everyone's help. Whether or not he is diagnosed with HIV, I will have to convince him of this too, which seems like an almost impossible task at this very moment.
My brother received a phone call from the doctor's office earlier today saying he would have to come back for a second round of testings before they reveal their results, which surprised him, since he was not aware of this during his first visit with the doctor. What could this possibly imply? Could the first test results have been inconclusive? Could they have in fact turned out to be positive? Is the doctor testing again for accuracy?
While researching, I read that two or more positive ELISA (Enzyme-linked immunosorbent assay) tests indicate an HIV diagnosis, which is then confirmed by one positive Western blot assay. I have also read that there are two different strains of HIV, HIV-1 (causes AIDS) and HIV-2 (causes an AIDS-like illness), but the latter is uncommon in the United States. There is so much information out there concerning HIV that I have a hard time trying to absorb every single detail into my mind. Does anyone recommend a respectable website?
I will also look into counseling services in his area. Nothing can replace the support of a family, but since we cannot be there for him in person, I am hoping this will become a suitable alternative. I know, in the end, he may not have HIV, and, yes, I realize this subject is sometimes stigmatized, but I greatly appreciate everyone's honesty and support. Like JennyMominRI wisely said, the only way to rid of the stigma so often related with HIV is to couragously speak up and educate others about this illness.

Best wishes to all and thanks once again! I will keep you updated as the days progress.
