Researchers have found in a new study that latent tuberculosis infection (LTBI) screening with interferon gamma release assay (IGRA)-only is more cost-effective than the two-step tuberculin Skin Test (TST)/IGRA testing strategy, preventing a higher number of cases of TB cases.
The study is published in the Pulmonology Journal.
Screening for latent tuberculosis infection (LTBI) in close contacts of infectious TB cases might include Tuberculin Skin Test (TST) and Interferon-Gamma Release Assays (IGRA), in combination or as single-tests. In Portugal, the screening strategy changed from TST followed by IGRA to IGRA-only testing.
