Learning Objectives:


After completing this course, participants will be able to:


  • Define the lupus anticoagulant.
  • Describe laboratory tests used to identify the lupus anticoagulant.
  • List preanalytical variables affecting lupus anticoagulant testing.
  • Compare ISTH vs. CLSI guidelines for lupus anticoagulant testing.

Who should attend? Practicing Pathologists, Residents, Doctoral Scientists, Pathologists’ Assistants, Laboratory Managers, Bench Supervisors, Bench Technologists & Technicians



A prolonged APTT (activated partial thromboplastin time[LN2]) is a very common finding in the clinical laboratory. Very often, these are discovered in patients during pre-admission testing for surgical procedures. This has the potential to delay surgery and may lead to unnecessary testing and increased patient anxiety. This webcast will address the prolonged APTT and describe different assays that can be used to identify a lupus anticoagulant. In addition, a testing algorithm to streamline testing will be introduced. At the end of this session, the laboratory scientist will be able to define the lupus anticoagulant, describe how lupus anticoagulant assays are used in the clinical laboratory, and identify reagents and methods that lead to more rapid diagnosis of the lupus anticoagulant.
