Mycobacteriology False–Positive Case Studies Learning Module and Toolkit The latest module of the Essentials for the Mycobacteriology Laboratory series provides laboratorians an opportunity to navigate through five real–world cases in which a false– positive Mycobacterium tuberculosis result may have been reported. The scenarios include examples of pre-analytical, analytical and post-analytical processes. Participants will use this interactive module to help identify and investigate potential false–positive results. Access the entire Essentials for the Mycobacteriology Laboratory series at www.aphl.org/TBTraining NEW! CDC’s False–Positive Investigation Toolkit: A Resource for Mycobacteriology Laboratories CDC’s False–Positive Investigation Toolkit was developed to provide mycobacteriology staff with updated resources to recognize potential false–positive results and to assist staff in false–positive investigations. TB control programs and healthcare providers may also find this information beneficial when investigating potential false–positive laboratory results. • Define false–positive results for MTBC. • Identify best practices to prevent false–positive results for MTBC. • Recognize possible scenarios for identifying potential false–positive results. • Describe the actions necessary to investigate potential false–positive results. • Summarize how the TB laboratory and the TB Control Program should collaborate to investigate false–positive results. • Describe the importance of developing both laboratory and TB Control Program guidance, policies and educational materials to be referenced by staff when necessary. • Identify follow-up actions if a determination of false–positive result is made. Find the toolkit on CDC’s website at bit.ly/CDCFPTool The toolkit includes job aids, posters and templates that can be modified for local use.
