Human immunodeficiency virus (HIV) is a retrovirus that progressively destroys CD4+ lymphocytes, making the body susceptible to attack by foreign infectious agents and numerous forms of cancer. HIV infection is tested via enzyme-linked...
The immune system begins to produce antibodies in an attempt to fight the HIV virus as soon as the virus enters the body. HIV/AIDS tests screens for and diagnoses an infection by either detecting the antibodies, or by testing virus levels in the...
When stimulated by an infectious agent or allergen, white blood cells within the body produce proteins called antibodies. Antibodies have the ability to bind selectively to a specific protein or compound, called an antigen, and the...
It takes an average of six to 12 weeks for the human immunodeficiency virus, or HIV, to be detectable, according to Avert, although there have even been rare cases when HIV is not detected until as long as six months after infection. Anyone...
