Selecting the Correct Specimen

This Medical Laboratory Science lesson in Molecular Diagnostics supports laboratory science learning and laboratory interpretation for medical laboratory students and professionals.

Match the ordered molecular assay to the specimen type the assay was validated for, wrong specimen type is a preanalytical failure.

Each objective is a clinical-laboratory skill for preanalytical and extraction practice.

  • Explain why molecular specimen requirements are assay-specific rather than universal
  • Match an ordered molecular assay to the specimen type listed in the institutional test menu or standard operating procedure (SOP)
  • Recognize wrong specimen type as a preanalytical failure that can produce false-negative, invalid, or unreliable results
