Status Information

Status
DEPRECATED
Comment
Based on extensive review of mappings and usage across Canada, Canada Health Infoway found that the limited use LABORDER codes are not being used. CHI and the Laboratory LOINC Committee agreed that these codes should be deprecated in order to minimize inadvertent mapping of observations to these terms (as has been reported).

Term Description

Created ONLY for ORDERING in response to request from Canada Health Infoway- a national standardization effort. The dashes in this case mean that the ordering provider does not care what property or scale is used in the observation performed in response to this order. LOINC is still pondering details about how this kind of item should be represented. So the representation might change in the future, but the term will still have the same usage and meaning.

LP15394-7   Antithrombin
Antithrombin is a small molecule that inactivates several enzymes of the coagulation system. It is a glycoprotein produced by the liver.

LP15394-7   Antithrombin
Antithrombin and antithrombin III refer to the same thing but today, however, antithrombin is the correct name. Antithrombin is a small glycoprotien, produced in the liver that inactivates several enzymes of the coagulation system including thrombin as well as factors Xa, IXa, XIa, XIIa, and kallikrein. Heparan sulfate (heparin), located on endothelial cells, binds to antithrombin causing a conformational change that results in its activation. Antithrombin deficiency is present in 0.17% of the general population. It accounts for 1.1% of unselected patients with venous thrombosis and up to 5% of patients younger than 70 years with thrombosis. Over 127 mutations in the antithrombin gene are known to cause hereditary antithrombin deficiency. Individuals heterozygous for antithrombin deficiency have a fivefold increased risk for venous thrombosis. Homozygous deficiencies are usually fatal. Source: Regenstrief Help
