Description

Latent tuberculosis infection (LTBI) affects nearly one-quarter of the global population and represents a critical reservoir for active TB, the leading infectious cause of death globally. LTBI is asymptomatic but can progress to active TB, causing morbidity, mortality, and fueling ongoing transmission. Efficient and accurate LTBI diagnostic and management strategies are fundamental to achieving TB elimination. However, healthcare providers and laboratory professionals encounter significant challenges in LTBI testing, from identifying appropriate patients for testing and selecting optimal diagnostic methods, to accurately interpreting results and implementing effective interventions.

Join Dr. Elizabeth Talbot as she presents evidence-based guidance on TB testing algorithms, including strengths and limitations of LTBI testing methods, along with strategies for identifying and prioritizing high-risk patient populations to optimize TB prevention programs.

Target audience

This activity is designed for physicians, lab supervisors, lab directors (and/or assistant directors), lab managers (supervisory and/or non-supervisory), and medical technologists.

Learning objectives

At the end of this session, participants will be able to:

  • Evaluate key features of the global TB epidemic and the public health and clinical impact of LTBI testing.
  • Compare the diagnostic performance of the tuberculin skin test (TST) and Interferon-Gamma Release Assay (IGRA) test methods.
  • Recognize high-risk populations and pre-analytical variables affecting test accuracy.
