Clinical Scorecard: Expanding Access to TB Testing

At a Glance

Key Highlights

• Introduction of near point-of-care nucleic acid amplification tests (NPOC-NAATs)
• Use of tongue swabs as an alternative sample type for TB testing
• Sputum pooling strategy to improve efficiency in resource-limited settings
• Decentralized testing models to reduce reliance on centralized laboratories
• Updated operational guidance and implementation toolkits to support integration

Guideline-Based Recommendations

Diagnosis

• Utilize NPOC-NAATs for initial TB detection
• Consider tongue swabs for patients unable to produce sputum

Management

• Implement sputum pooling to enhance testing efficiency

Monitoring & Follow-up

• Adopt standardized diagnostic algorithms for new testing tools

Risks

• Need for validation of alternative specimens and updated protocols

Patient & Prescribing Data

Individuals in resource-limited settings and those with difficulty providing sputum samples

NPOC-NAATs may be available at lower costs than existing molecular platforms

Clinical Best Practices

• Integrate new diagnostic tools into national TB programs
• Provide training materials for healthcare providers on new testing methods
