SUMMARY
Tuberculosis is a communicable disease caused by infection with M.tuberculosis (MTB)complex organisms (M. tuberculosis, M. bovis, M. africanum), which typically spread to new hosts via airborne droplet nuclei from patients with respiratory tuberculosis disease. It is one of the most important health threatening problems worldwide. The World Health Organization estimates that one third of the worldAcA A s population is infected with M.tuberculosis. Each person carrying latent TB infection (LTBI) has approximately a 10% chance of progressing to active disease.
Interferon Gamma Release Assay (IGRA) measure a personAcA A s immune reactivity to M.tuberculosis. T lymphocytes from most persons that have been infected with M.tuberculosis will release IFN-A A when mixed with special antigens derived from M.tuberculosis. IGRA is whole-blood test that can aid in diagnosing Mycobacterium tuberculosis infection, including both latent tuberculosis infection (LTBI) and tuberculosis (TB) disease.
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-A A . This kit uses ELISA method for quantitative detection the specific IFN-A A released by cells to determine Mycobacterium tuberculosis infection.
