What is beta-2-glycoprotein antibody IgG?

Beta-2 glycoprotein antibody is considered one of the primary autoantibodies called antiphospholipid antibodies that mistakenly target the body’s own lipid-proteins (phospholipids) found in the outermost layer of cells (cell membranes) and platelets.

What does a positive beta-2-glycoprotein mean?

Interpretation. Provides information to assist in interpretation of the test results. Strongly positive results for beta-2 glycoprotein 1 (beta-2 GP1) antibodies (>40 U/mL for IgG and/or IgM) are diagnostic criterion for antiphospholipid syndrome (APS).

What is the normal range for beta-2-glycoprotein?

Normal: β2 GPI IgG ≤ 20 SGU U/mL. β2 GPI IgM ≤ 20 SMU U/mL.

What does it mean to be lupus anticoagulant positive?

If your lupus anticoagulant test is positive, this means you have antibodies in your blood. The test will also measure whether they are within the normal range. Normal results can vary from lab to lab, but a normal range is from 20 to 39 grams per liter (GPL) or micropulse lidar (MPL) units.

What does a low beta-2-glycoprotein mean?

The frequency of anti-beta2-glycoprotein I antibodies is low and these antibodies are associated with pulmonary hypertension in mixed connective tissue disease. Lupus.

What does a negative beta-2-glycoprotein mean?

If subsequent testing is negative, then it is likely that the antibodies were temporary. This may be seen if the patient is suffering from an acute infection. A single positive beta-2 glycoprotein 1 antibody result is not diagnostic of APS, and a negative result does not rule out antiphospholipid antibody development.

What is beta 2 IgA glycoprotein?

Beta-2 glycoprotein 1 (beta-2 GP1, also called apolipoprotein H) is a 326-amino acid polypeptide synthesized by hepatocytes, endothelial cells and trophoblast cells. It contains 5 homologous domains of approximately 60 amino acids each.

What does a low beta 2 glycoprotein mean?

How long can you live with lupus anticoagulant?

The cumulative relative survival was 95.0% (95% CI, 88.5-98.8) after 5 years and 87.7% (95% CI, 76.3-95.6) after 10 years.

Does antiphospholipid syndrome make you tired?

Some other people with APS, particularly those who also have lupus, get a rash, joint pains, migraines and become very tired, even when they aren’t pregnant or don’t have blood clots. It is not unusual for people with APS to have periods of tiredness, forgetfulness, confusion and anxiety.

What does high cardiolipin IgG mean?

Moderate to high levels of cardiolipin antibodies that persist when tested again 12 weeks later indicate the likely continued presence of that specific antibody, which may be associated with an increased risk of excessive clotting or recurrent miscarriages.

What is beta 2 glycoprotein?

Beta-2 glycoprotein antibody is considered one of the primary autoantibodies called antiphospholipid antibodies that mistakenly target the body’s own lipid-proteins (phospholipids) found in the outermost layer of cells (cell membranes) and platelets.

What is beta-2 glycoprotein I AB, Iga?

Beta-2 glycoprotein 1 antibody is an autoantibody that is associated with inappropriate blood clotting. This test detects and measures one or more classes ( IgG, IgM, or IgA) of beta-2 glycoprotein 1 antibodies. Beta-2 glycoprotein antibody is considered one of the primary autoantibodies called antiphospholipid antibodies…

What does a positive anticardiolipin IgM mean?

What does a positive cardiolipin test mean? A positive result means that cardiolipin antibody was detected in the blood. As mentioned earlier, the presence of cardiolipin antibodies may indicate several diseases, such as: Syphilis.

How do Type B antibodies react to Type B antigens?

if there is a reaction (agglutination/clumping) = that antigen is present; the antibody attacks the antigens we know that antigen is present because of the clumping; reaction with A = A antigen; type A blood reaction with B = B antigen; type B blood reaction with A and B = type AB blood no reaction = no antigen; type O blood
