Extraction Failure and Troubleshooting

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

Recognize common nucleic acid extraction failure patterns, hold result release when integrity is in doubt, and follow SOP actions such as recollect or re-extract, never inventing a negative from a failed run.

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

  • Recognize practical patterns that suggest extraction failure or related preanalytical problems
  • State the safe default action when extraction integrity is in doubt: hold release and follow SOP
  • Choose recollect versus re-extract actions only as directed by institutional SOP, never invent a negative from a failed run
