  1. Excerpt from 2015 Kenyan guidelines
  2. aXpert® recommended for all presumptive paediatric TB OR HIV-infected smear negative OR drug resistant cases OR retreatment cases i.e. relapse/defaults/treatment failures in adults OR suspected drug resistant TB
  3. bMicroscopy recommeded for all recommended pulmonary tuberculosis cases
  4. cCulture/LPA recommended for retreatment cases ((i.e. relapse/defaults/treatment failures) regardless of age
