SARS-CoV-2 Supply Shortages and Tuberculosis Diagnostics: Current Issues Requiring Immediate Solutions

Area of Science:

• Microbiology
• Public Health
• Clinical Diagnostics

Background:

• The COVID-19 pandemic has severely impacted global manufacturing, leading to widespread shortages of critical laboratory supplies.
• Specific shortages include probe-based kits essential for detecting the Mycobacterium tuberculosis complex in liquid cultures.
• These supply chain disruptions threaten established laboratory testing algorithms and pose risks to public health surveillance in the United States.

Purpose of the Study:

• To highlight the impact of SARS-CoV-2-related supply chain disruptions on Mycobacterium tuberculosis complex detection.
• To underscore the urgent need for alternative methods and modified testing strategies due to the unavailability of standard diagnostic kits.
• To inform public health and laboratory professionals about the consequences for tuberculosis diagnostics in the US.

Main Methods:

• This study is a review and analysis of the current supply chain challenges impacting diagnostic laboratories.
• It examines the implications of probe-based kit shortages for Mycobacterium tuberculosis complex detection.
• The analysis considers the lack of immediate FDA-approved alternatives and the necessity for adaptive strategies.

Main Results:

• Significant shortages of probe-based kits for Mycobacterium tuberculosis complex detection have been identified.
• The absence of commercially available, FDA-approved replacements creates a critical gap in diagnostic capabilities.
• Existing laboratory testing algorithms are at risk of disruption, potentially impacting tuberculosis control efforts.

Conclusions:

• Laboratories face an urgent need to identify and implement alternative methods for Mycobacterium tuberculosis complex detection.
• Modifying current testing algorithms is crucial to ensure continuity of care and public health protection.
• Proactive planning and adaptation are essential to mitigate the impact of supply chain disruptions on tuberculosis diagnostics.
