INTENDED USE：

HIV Type I/Type II Total Antibody Test is a rapid and convenient immunochromatographic assay used for the qualitative detection of antibodies against HIV type 1 and type 2 in human serum, plasma or whole blood sample. It is intended for professional use as an aid in diagnosis of HIV infections. This assay provides only a preliminary result and all positive specimens should be confirmed with other qualified assays.

SUMMARY：

The human immunodeficiency virus (HIV) is a lentivirus that causes acquired immunodeficiency syndrome (AIDS). HIV attacks the immune system, resulting in a chronic, progressive illness that leads to life-threatening opportunistic infections. There are two types of HIV: HIV-1 and HIV-2. HIV-1 has been isolated from patients with AIDS and AIDS related complexes, and from healthy persons with high potential risks of developing AIDS. Patients with HIV-2 are found primarily in parts of West Africa. Both types are transmitted by sexual contact, through blood, or from mother to child and appear to cause clinically indistinguishable AIDS. HIV infections are staged by CD4 cell counts and clinical symptoms. Not all people progress through all “stages” and the time frames may also vary greatly from person to person. Treatment with anti-retrovirals increases the life expectancy of people infected with HIV. HIV-1 and HIV-2 are similar in their morphology, cell tropism, host interaction and generic structure. Serological studies have determined that HIV-1 and HIV-2 have multiple common epitopes in core antigens but much less so in the envelope antigens. The clinical diagnostic issues related to HIV are the detection of antibodies to HIV1/2 in human plasma, serum or whole blood by immunoassay. HIV Type I/Type II Total Antibody Test is an antibody-capture immunochromatographic assay, detecting the presence of HIV1/2 antibodies in blood samples.
