Mycobacterium tuberculosis 

APHL develops, promotes, updates, and disseminates guidance related to Tuberculosis (TB) testing best practices nationwide in close collaboration with the Division of Tuberculosis Elimination (DTBE) at CDC. Commonly considered a disease of the past, TB is resurging in new and virtually untreatable forms that have the potential to cause debilitating disease in our nation's most vulnerable residents. Diagnostic laboratories play instrumental roles in fighting TB by identifying and isolating Mycobacterium tuberculosis, the causative agent of TB disease through the use and application of novel diagnostic techniques. ​​

11th National Conference on Laboratory Aspects of Tuberculosis
April 23-24, 2019 
Marriott Marquis Hotel - Atlanta, Georgia

APHL biennially hosts the National Conference on Laboratory Aspects of Tuberculosis alongside the National TB Controllers Association (NTCA) National Conference. Please visit the ​APHL TB Conference webpage for registration, program, and other conference-related information! APHL Conference Proceedings from the 8th-10th National Conferences are available (see side bar).

Education and Training  

A set of free and interactive training modules, the “Essentials for the Mycobacteriology Laboratory: Promoting Quality Practices” are an on-demand resource to promote competency, quality and safety in common mycobacteriology testing practices. Designed for laboratorians at all levels of experience, each module in the series is complimented by references and resources. Modules are also available in PDF format (with and without narrative notes) for use in laboratory training programs.

Drug Susceptibility Testing

In 2015, APHL in collaboration with CDC established a National PHL Drug Susceptibility (DST) Reference Center for Mycobacterium tuberculosis to provide quality-assured drug susceptibility testing for eligible US public health laboratories. The reference center serves as an extension of CDC’s Division of TB Elimination Laboratory Branch providing services that are harmonized with and complementary to those available at CDC.

The TB subcommittee has developed and published white papers on Issues in Mycobacterium tuberculosis Complex (MTBC) Drug Susceptibility Testing covering current guidelines, recommendations and research findings.

Self-Assessment Tool

In 2013 APHL and CDC updated the  Mycobacterium Tuberculosis: Assessing your Laboratory, a tool designed originially in 1995, to assist laboratories in the assessment of the quality of their laboratory’s TB diagnostic practices. The2013 updates were made to reflect profound changes to TB diagnostics and was also converted to an electronic TB self-assessment tool. Laboratories are encouraged to incorporate the use of this tool into their current Quality Assurance practices as a means to determine the existence of areas within individual laboratories that may be in need of improvement. APHL is in the midst of another update planned for release in early 2019.
