How does the new test for HIV1, HIV2, and HIV-O antibodies?
The new third generation, three line test now uses double antigen recombinant proteins, which dramatically improve sensitivity and specificity. This assay is a chromatographic lateral flow immunoassay, containing filter membrane coated with HIV-1 and HIV-2 specific. antigens and colored gold colloidal reagents labeled with HIV-1, HIV-2, and HIV-O specific antigens There are three regions on the membrane of the control window. The first region is the “C” line. A light pinkish-red or burgundy colored band in this control region of the test should always appear, regardless of the presence of HIV-1, HIV-2, and/or HIV-O antibodies. It serves as an internal qualitative control for the test’s system. T region or test area has two testing lines. The first line under the “T” region of the membrane is situated slightly closer to the “C” region and searches for HIV-O antibodies.
