19001717 . Tuberculosis is a communicable disease caused by infection with M. tuberculosis (MTB) complex organisms, which typically spread to new hosts via airborne droplets from patients with respiratory tuberculosis disease.
. The TB IgG/IgM Combo test is a screening test to aid in the diagnosis of TB. A positive result should not be the sole or definitive basis for determining M. tuberculosis infection. Further medical evaluation and diagnostic evaluation for active tuberculosis (e.g., AFB smear and culture, chest X-ray) are warranted.
. Positive IgM indicates recent infection, while poasitive IgG indicates previous or chronic infection.
