About the Program
In the United States, the rate and number of tuberculosis (TB) cases has been steadily declining since 1993. While this is encouraging, more effort is needed to control this disease and appropriate screening is at the center of that fight. Two types of TB screening tests are available in the United States: tuberculin skin tests (TSTs) and interferon gamma release assays (IGRAs). IGRAs are faster, more accurate, and less prone to misinterpretation than TSTs, but require careful technique when collecting and preparing patient samples for testing. This online tutorial will provide practical information that will help nurses, technicians, and laboratory staff obtain and process IGRA specimens consistent with the approved labeling of the tests to assure high quality control and avoid unnecessary treatment referrals.

Target Audience
This activity is intended for nurses and clinical laboratory staff involved in the collection and processing of tuberculosis screening tests.

Learning Objectives
At the conclusion of this activity, participants should be able to:

  • Differentiate between latent and active TB infection
  • Discuss the differences between TSTs and IGRAs in TB surveillance and diagnosis
  • Explain the possible consequences of false-positive and false-negative TB tests and what it would mean for misdiagnosed individuals and public health
  • Describe the steps involved in preparing a patient sample for IGRA testing
  • Identify and correct common sources of error in IGRA sample processing
