The HIV TRI-DOT test is a visual, rapid, sensitive and accurate immunoassay for the differential detection of HIV-1 & HIV-2 antibodies (IgG,IgM & IgA) in human serum or plasma using HIV-1 & HIV-2 Antigens immobilized on an immunofiltration membrane. The test is a screening test for Anti HIV-1 and HIV-2 and is for in vitro diagnostic use only.
- Rapid visual test ,based on Flow Through Technology.
- Differential detection of HIV-1 & HIV-2.
- Detection of group ‘O’ & subtype ‘C’.

HIV antigens are immobilized on a porous immunofiltration membrane. Sample and reagents pass through the membrane and are absorbed into the underlying absorbent. As the patient’s sample passes through the membrane, HIV antibodies, if present, bind to the immobilized antigens. Conjugate binds to the Fc portion of the HIV antibodies to give distinct pinkish purple DOT(s) against a white background.
