Area of Science:
- Infectious Diseases
- Microbiology
- Public Health
Context:
- Tuberculosis remains a significant global health challenge.
- Latent tuberculosis infection (LTBI) is a major reservoir for M. tuberculosis.
- Effective diagnostic tools are crucial for tuberculosis control programs.
Purpose:
- To outline the indications for tuberculin skin testing (TST) in identifying LTBI.
- To describe the technical procedures for administering and interpreting TST.
- To provide guidelines for managing individuals with a positive TST result.
Summary:
- The tuberculin skin test (TST) is the established method for diagnosing latent M. tuberculosis infection in asymptomatic individuals.
- Targeted TST is a key strategy for tuberculosis elimination in low-prevalence settings.
- This report covers TST indications, methodology, interpretation criteria, and follow-up actions for positive results.
Impact:
- Facilitates targeted screening for LTBI, enabling early intervention.
- Supports the strategic implementation of tuberculosis control measures in diverse healthcare settings.
- Aids healthcare providers in accurate diagnosis and management of potential tuberculosis cases.
