aPTT.lupus sensitive W excess phospholipid (LA confirm)

Confirm aPTT

Definition

  • If the coagulation defect corrects with excess phospholipid, it confirms the likely presence of phospholipid antibodies and the LA syndrome. Platelets, bilayer and hexagonal phospholipids are variously used as the source of excess phospholipids and this term covers them all. The use of one term for these variations reduces mapping work for practices that import laboratory results, but laboratories that use platelets or hexagonal phospholipids and think it important to distinguish their source can use 3284-7 or 3282-1, respectively, instead of this term.
