IGRA is the preferred method of early detection of M. tuberculosis. The TB blood test (IGRA) measures T cell-mediated immune response (the release of Interferon gamma, IFN-γ) by mixing Mycobacterium antigens with whole blood in vitro.
Detect it early. During the early M. tuberculosis infection stage, cellular immune responses play more dominate roles than humoral response when bacterial loads are low. IGRA is an in vitro blood test using memory T-cells released IFN- γ as a marker of M. tuberculosis infection.

VRL offers a cell-based in vitro assay in two formats for the detection of anti-AAV neutralizing antibodies:

1. The screening assay (qualitative neutralization assay): the result is reported as positive or negative for the 3 dilutions (1:10, 1:20, 1:40) of each serum sample.
2. The neutralizing antibody titer (or 50% inhibitory dose [ID50]) assay: (quantitative neutralization assay): each serum sample is 2-fold serial diluted from 1:10-1:5120, the result is reported as a titer value at which 50% inhibition of virus transduction is calculated.
