Each objective is a clinical-laboratory application skill, not disease biology or treatment advice.

  • Map TB molecular orders to clinical question, specimen, target, method, controls, result categories, and limitations
  • Explain that detecting Mycobacterium tuberculosis complex nucleic acid does not by itself prove viable organisms or replace culture when culture is still needed
  • State that selected resistance-marker detection may not replace phenotypic antimicrobial susceptibility testing (AST) in every situation
