Immunocytochemistry (ICC) is another valuable form of immunostaining. Supplement teStS Western Blot test: The confirmatory test commonly employed is the Western Blot test. Like the screening assays, each of these detected only IgG anti-HIV and had antibody-negative. ![]() Two procedures were FDA cleared as confirmatory tests for HIV-1 antibody only: the Western blot assay and an HTLV III immunofluorescence assay (IFA) (7, 8). Such data would be useful for studying diseases such as AIDS, in which the normal function of CD8 cells is crucial for slowing disease progression. There is comparable sensitivity and specificity between RDTs and Western blot and a greater reduction in turnaround time using RDTs10-16. Similarly to syphilis testing, a second level of testing was added to improve specificity. It is now possible to count the number of CD8 cells, determine their relative numbers versus the other cell types present, and determine the location of these cells within this tissue. In this example, a mAb against CD8 was used to stain CD8 cells in a section of tonsil tissue. The first two strips are a negative and a positive control, respectively. ![]() \), a section of tissue can be stained to visualize the various cell types.
