ABOUT

Focus on:

  • New diagnostic technologies
  • Community participation (TB Champions)
  • Goal: TB Elimination in India

EVOLVING DIAGNOSTIC LANDSCAPE FOR TB

  • Shift in TB DiagnosisàEarlier Method: Sputum smear microscopy
  • Modern Methods: Molecular Tests (NAAT / CBNAAT / TrueNat)
  • Role of Technology: Portable Chest X-Ray (CXR) + AI
  • Used in: Community screening
  • New Testing Innovations: Tongue swab / Non-sputum samples

Key Challenges in Diagnosis

  • Unequal Access: Rural & remote areas lack: Testing infrastructure
  • Delay in Diagnosis: Multi-step testing causes: Treatment delays
  • Asymptomatic TBàMany cases: No symptoms: Makes screening difficult
  • Extra-Pulmonary TB (EPTB)à Difficult to detect: Expensive diagnosis

National TB Elimination Programme (NTEP)

  • Provides: Free diagnosis & treatment
  • Expanding: Molecular testing, AI screening

TB Champions

  • TB survivors who help others
  • Role: Awareness, Counselling, Reducing stigma

Way Forward

  • Expand molecular testing access
  • Develop: Cheap, rapid biomarkers
  • Strengthen: Sample collection system
  • Increase: Investment in R&D
  • Use: AI + portable diagnostics
