Term Description

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

LP32427-4   Coagulation surface induced.lupus sensitive
Activated partial thromboplastic time.lupus sensitive (aPTT-LA), also called sensitive aPTT, is a screening laboratory test often used as the first step in a testing cascade to detect the presence of lupus anticoagulants (LA), which are autoantibodies associated with excess clot formation, excess bleeding, and repeated miscarriages. Sensitive aPTT has less phospholipid relative to the standard aPTT reagent, which makes the test more sensitive to the presence of phospholipid antibodies.

LP32427-4   Coagulation surface induced.lupus sensitive
The amount of phospholipid included in the aPTT-LA reagent is diminshed relative to the standard aPTT reagent. Source: LOINC partner 1

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.
