Screening for tuberculosis infection and disease is crucial in primary care. The Mantoux tuberculin skin test (TST) is recommended for all ages, with interpretation based on individual risk factors.

Area of Science:

  • Public Health
  • Infectious Diseases
  • Primary Care Medicine

Background:

  • Tuberculosis (TB) infection affects millions in the US, with certain groups at higher risk for active disease.
  • Primary care plays a vital role in screening for latent tuberculosis infection and active TB disease.

Purpose of the Study:

  • To outline current recommendations for tuberculosis screening in primary care.
  • To emphasize the importance of risk assessment in interpreting screening tests.

Main Methods:

  • The Mantoux method using 5TU purified protein derivative (PPD) is the recommended tuberculin skin test (TST).
  • Anergy testing is no longer widely recommended as a companion to TST.
  • Interpretation of TST results requires consideration of age, lifestyle, medical comorbidities, and environmental risk factors.

Main Results:

  • The Mantoux TST is the standard for tuberculosis screening across all age groups.
  • Risk stratification is essential for accurate interpretation of TST results, particularly in high-risk populations.
  • Careful evaluation of risk factors is necessary when assessing tuberculosis risk in refugee and immigrant populations.

Conclusions:

  • Effective tuberculosis screening in primary care relies on appropriate testing and nuanced interpretation.
  • Individualized risk assessment is key to managing tuberculosis in diverse patient populations.
  • Continued vigilance and adherence to recommended screening protocols are essential for tuberculosis control.
