Term Description

Confirmatory lupus sensitive aPTT, measured after heparin neutralization, which removes the effects of any heparin that may be present in the sample. Heparin neutralization methods include the addition of heparinase, an enzyme that breaks down heparin, and heparin adsorption, in which a substance is added that binds the heparin that is present.

Part Descriptions

LP185878-8   Coagulation surface induced.lupus sensitive.excess phospholipid
Activated partial thromboplastic time with excess phospholipid is a confirmatory lab test for lupus anticoagulants (LA), which are phospholipid autoantibodies associated with excess clot formation, excess bleeding, and repeated miscarriages.Confirmatory testing measures aPTT in the presence of excess phospholipid, which saturates the antibody binding sites and thereby diminishes the inhibitory effect of the LA, resulting in a normalization of the aPTT. The aPTT screen to confirm ratio is calculated as Screen aPTT/Confirm aPTT, and the aPTT percent correction is calculated as [(Screen aPTT - Confirm aPTT)/Screen aPTT]x100.

LP411053-4   post heparin neutralization
The "post heparin neutralization" challenge in LOINC includes a variety of methods to remove the effect of heparin from a sample before testing. These methods include the addition of heparinase, an enzyme that breaks down heparin, and heparin adsorption, in which a substance is added that binds the heparin that is present.
