Latent tuberculosis infection (LTBI)
Latent tuberculosis infection (LTBI) is a state of persistent immune response to stimulation by Mycobacterium tuberculosis antigens without evidence of clinically manifested active TB. A direct measurement tool for M. tuberculosis infection in humans is currently unavailable. One-third of the world’s population is estimated to have LTBI: they do not have active TB disease but may develop it in the near or remote future, a process called “TB reactivation”.
