Mycobacterium Tuberculosis Specific T Cell Mediated Immune Response 
Detection Kit(ELISA)

Read the package insert carefully and completely before performing the assay. Follow the instructions and do not modify them. Only by strict adherence to these instructions, the erroneous results can be 
avoided and the optimal performance ofthis kitachieved.


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.


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 world’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 person’s immune reactivity to M.tuberculosis. Tlymphocytes from most persons that have been infected with M.tuberculosis will release IFN-γ 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.
