Lupus Anticoagulant blood testing is usually used to determine the cause of thrombosis, pregnancy complications or a prolonged aPTT test. Lupus Anticoagulant is a protein in the blood. When this rises it increases the risk of blood clots in the veins and arteries. These clots can often lead to strokes, heart attacks pregnancy complications and more.
Lupus anticoagulants (LA) are members of a family of antibodies with phospholipid specificity. LA may be defined as an immunoglobulin, IgG or IgM or a mixture of both, that interferes with one or more of the in vitro PL dependent tests of coagulation.
