About this file
This document provides key elements for mycobacteriology laboratory procedures to support a clinical trial conducted by the Tuberculosis Trials Consortium and AIDS Clinical Trials Group Network. The key elements outline standardized procedures for sputum collection and transport, processing, smear microscopy, rapid molecular testing, solid and liquid media culture, and drug susceptibility testing. Adherence to the specified protocols and inclusion of quality controls are intended to ensure the quality and comparability of mycobacteriology results across laboratory sites. Confirmation of Mycobacterium tuberculosis complex for positive cultures is also included as a key element. Signatures from the principal investigator, study coordinator, and laboratory director are required to agree that the local laboratory's standard operating procedures incorporate these key elements before participant enrollment can proceed at each clinical trial site.

Study 31/ACTG 5349 Key Elements of Mycobacteriology Laboratory Procedures:
Towards Harmonization of Mycobacteriology in TB Trials
J.6 - Example Key Elements Page 1 of 9
Background
The proposed approach towards harmonization of Standard Operating Procedures (SOPs) across the Tuberculosis Trials Consortium (TBTC) and AIDS Clinical Trials Group (ACTG) Network Tuberculosis (TB) laboratories included, (1) identifying Key Elements in Mycobacteriology laboratory procedures that have the greatest impact on data quality and, (2) harmonizing those elements across all Mycobacteriology Laboratories in both networks. Rather than create new SOPS, Mycobacteriology Laboratory procedures should be reviewed for the presence or absence of the necessary Key Elements. Most clinical Mycobacteriology Laboratories already have SOPS and have either been accredited or are in the process of accreditation. Creating new SOPs would be burdensome in terms of time and resources, and would duplicate the efforts of other universal lab manuals that are currently available (e.g., GLI Mycobacteriology Laboratory Manual)
Cross-network harmonization and implementation of the Key Elements of Mycobacteriology Laboratory Procedures begins with TBTC Study 31, ACTG #5349, a multi-network phase three trial to evaluate safety and efficacy of shortened TB treatment regimens for acute pulmonary TB.
The Key Elements for TBTC Study 31, ACTG #5349 are detailed in Table 1 below. These are in agreement with the Key Elements developed by the ACTG Tuberculosis Transformative Science Group (TB TSG) Lab Core Team. Good Clinical Laboratory Practices (GCLP) and quality assessment (QA) activities are not considered as key elements but must be a part of the Mycobacteriology Laboratory procedures, and laboratory-specific Quality Management manuals. These Key Elements are directed towards Mycobacteriology results used as endpoints in TB drug trials; however, Key Elements of rapid drug susceptibility tests are included as the quality of these results and turnaround times are important in screening for subject eligibility. Likewise, quality indirect Drug Susceptibility Testing (DST) results are needed to ensure safety for subjects enrolled in the study.
How to Use Key Elements of Mycobacteriology Laboratory Procedures
1. Review the Key Elements for Mycobacteriology Laboratory Procedures
2. Ensure your laboratory SOPs for Mycobacteriology include each Key Element

i If not possible to collect at least 1 mL expectorate sputum, use local procedures for sputum induction, when necessary ii When the distance between the clinic and laboratory is great (i.e., the clinic ships the specimen to a regional laboratory), the specimen should be maintained on cold chain and received at the laboratory no more than three to five days after collection.
iii Use of a refrigerated centrifuge is preferred.
iv For guidance on how to achieve accurate and precise resuspension volumes, please see Study 31/ACTG 5349 Mycobacteriology Laboratory Reference Manual.
