Lupus anticoagulants (LAs) are a type of antibody produced by your body’s immune system. While most antibodies attack disease in the body, LAs attack healthy cells and cell proteins. They attack phospholipids, which are essential components of cell membranes.

What does it mean if lupus anticoagulant is positive?

The presence of an antiphospholipid antibody such as the lupus anticoagulant and anticardiolipin antibody in an individual is associated with a predisposition for blood clots. Blood clots can form anywhere in the body and can lead to stroke, gangrene, heart attack, and other serious complications.

Why is it called lupus anticoagulant?

Lupus anticoagulant in living systems cause an increase in inappropriate blood clotting. The name derives from their properties in vitro, as these antibodies increase laboratory coagulation tests such as the activated partial thromboplastin time (aPTT).

Can I donate blood if I have lupus anticoagulant?

You can’t donate blood if you have lupus plus any of the following: Anemia. Abnormal liver function tests (liver dysfunction) If the disease is active (not in remission)

Can you live a normal life with antiphospholipid syndrome?

When APS is managed properly, the majority of people with the illness can live normal, full lives.

Does antiphospholipid syndrome go away?

There’s no cure for antiphospholipid syndrome, but medications can reduce your risk of blood clots.

What is the life expectancy of someone with APS?

However, subsets of patients continue to have thrombotic events despite aggressive therapies. In these patients and in patients with catastrophic APS, the disease course can be devastating, often leading to significant morbidity or early death. In large European cohort studies, 10-year survival is approximately 90-94%.

What are lupus anticoagulants?

These antibodies — also known as lupus anticoagulants due to their prevalence in patients with systemic lupus erythematosus — are extremely heterogeneous and are directed against a wide variety of anionic phospholipids, including cardiolipin, ß2 glycoprotein 1 (B2GP1), cell-membrane phosphatidylserine, and many others.

What do the results of my lupus test mean?

Ask your healthcare provider what your test results mean for you. The test results will show whether lupus anticoagulant antibodies are present in the blood. If your test shows they are, the test should be repeated in several weeks to confirm.

What are lupus antibodies and how do they work?

Clots can lead to heart attacks, strokes, pulmonary emboli, and deep vein thromboses. These happen when blood clots form in the deep veins of the body. These antibodies are called lupus antibodies because they were first discovered to be related to lupus. But not everyone who has lupus has these antibodies.
