In Vitro Diagnostic Use Only
This kit contains reagents sufficient for testing of maximum of 28
specimens in a test run.
1. INTENDED USE
This kit is an enzyme-linked immunosorbent assay for quantitative detection of Interferon Gamma (IFN-γ) that responds to in-vitro stimulation by Mycobacterium tuberculosis antigens in fresh human whole blood. It is intended for use as an aid in the diagnosis of tuberculosis (TB) infection.
2. PRINCIPLE OF THE TEST
This kit uses the principle of IGRA combined with enzyme linked
immunosorbent assay (ELISA) to
measure specific antigen mediated immune response strength. The
antigens selected for stimulation is
specific fragments that pathogenic Mycobacterium tuberculosis have,
but BCG vaccine and other
Mycobacterium do not have. The patients infected with Mycobacterium
tuberculosis have specific T
lymphocytes which can identify these antigens and T lymphocytes
will be stimulated to proliferate and
release cytokines such as IFN-γ. This kit uses ELISA method for
quantitative detection the specific IFN-γ
released by cells to determine Mycobacterium tuberculosis
infection.
