Course provided by LabCE.

This course discusses the characteristics of the antiphospholipid syndrome (APS) and its relationship to the lupus anticoagulant (LA) while identifying the clinical implications of LA. Specimen collection and handling of specimens used in testing for LA is covered. From a laboratory testing standpoint, algorithms and recommended guidelines for lupus testing are included along with the principles of the laboratory testing used to identify the LA. Lastly, treatment modalities for persons with LA are discussed.
