That being said, the advances in HIV diagnoses and treatment have come a very long way since the 80s and there is no reason to believe that a blood test would not pick up the antibodies if they are present. To believe otherwise is an irrational fear that needs to be addressed by a mental health professional, not an infectious disease specialist.

its a real serious question needs attention and i am longing for the answers
