Lupus anticoagulant (also known as lupus antibody, LA, LAC, or lupus inhibitors) is an immunoglobulin that binds to phospholipids and proteins associated with the cell membrane.Lupus anticoagulant is a misnomer, as it is actually a prothrombotic agent.Lupus anticoagulant antibodies in living systems cause an increase in inappropriate blood clotting. The name derives from their properties in vitro, since in laboratory tests, these antibodies increase aPTT.upus anticoagulant is a misnomer, as it is actually a prothrombotic agent.

In brief: Possibly. Anaphylaxis is a life threatening allergy reaction that occurs within minutes to hours of being exposed to the allergen in question. Very rarely one can see anaphylaxis that is delayed and not occur for a couple of hours after exposure. More commonly one sees anaphylaxis that occurs immediately then the symptoms recur hours later -- this is called a biphasic response. In brief: Possibly.
