SUMMARY

AIDS, short for Acquired Immunodeficiency Syndrome, is a chronic and fatal infecious disease caused by the Human Immunodeficiency Virus (HIV), which is transmitted mainly through sexual intercourse and sharing of syringes, as well as through mother-to-child transmission and blood transmission. HIV is a retrovirus that attacks and gradually destroys the human immune system, causing a decrease in immune function and making the body more susceptible to infection and eventually death. HIV antibody testing is important for the prevention of HIV transmission and the treatment of HIV antibodies.

PRINCIPLE OF THE PROCEDURE

This kit uses colloidal gold immunochromatographic analysis technology for qualitative detection of HIV (1/2) antibodies to human immunodeficiency virus in human serum/plasma/whole blood samples. The test strips contain HIV (1/2) antigen that pre-fixed at test area (T) and Goat anti-chicken IgY antibody that prefixed at control area (C) on the membrane. Label pad contains pre-coated colloidal gold labeled HIV (1/2) antigen and chicken IgY antibody. When a positive sample is detected, the HIV antibody in the sample can bind to the colloidal gold labeled HIV (1/2) antigen to form an immune complex. By chromatographic effect, the complex and the sample flow toward absorbent paper inside nitrocellulose membrane. When passing through test area (T), the complex binds with the coated HIV (1/2) antigen to form “HIV (1/2) antigen-HIV (1/2) antibody-colloidal gold-labeled HIV (1/2) antigen” complex and thus agglutinate and become colored. If the sample is negative, no HIV antibodies are present in the sample, so that no immune complex can be formed, and there will be no red band at the test area (T). No matter whether HIV antibodies are present in the sample, the remaining colloidal gold labeled chicken IgY binds to the Goat anti-chicken IgY antibody coated at the control area (C) and agglutinates to aggregate and become colored. Thus, a red band will appear in control area (C). Color band appearing at control area (C) is used to judge whether the sample is sufficient and whether the chromatographic process conforms to normal standard. It can also be used as internal control standard of the reagent.
