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

  • Describe the purpose of process/extraction controls used with nucleic acid extraction
  • State what a passing extraction control confirms about recovery or extraction integrity
  • Recognize that a failed extraction or process control makes the related result invalid until resolved per SOP
