What is a normal range for beta-2-glycoprotein?
Normal: β2 GPI IgG ≤ 20 SGU U/mL. β2 GPI IgM ≤ 20 SMU U/mL.
What does a high beta-2-glycoprotein IgA mean?
A positive beta-2 glycoprotein 1 antibody test may indicate that you have antiphospholipid syndrome (APS), as they are most frequently seen with this condition. If the test is positive, it will be repeated about 12 weeks later to determine whether it is persistent or temporary.
What is normal range for antiphospholipid antibody?
The reference range findings are as follows: Less than 15 immunoglobulin G (IgG) phospholipids units (GPL): Absent or none detected. Less than 12 immunoglobulin M (IgM) phospholipids units (MPL): Absent or none detected.
What is beta 2 glycoprotein antibody test for?
Beta-2 glycoprotein 1 antibody tests are primarily used along with cardiolipin antibody and lupus anticoagulant testing to help diagnose: Antiphospholipid syndrome (APS) The cause of an unexplained blood clot (thrombotic episode) The cause of recurrent miscarriages in women.
What does beta 2 glycoprotein do?
beta2GPI is involved in the coagulation pathway, exerting both procoagulant and anticoagulant activities. Plasma from beta2GPI-deficient mice exhibits impaired thrombin generation in vitro.
What is beta-2 glycoprotein antibody test for?
What is antiphospholipid antibody positive?
Antiphospholipid (AN-te-fos-fo-LIP-id) syndrome is a condition in which the immune system mistakenly creates antibodies that attack tissues in the body. These antibodies can cause blood clots to form in arteries and veins. Blood clots can form in the legs, lungs and other organs, such as the kidneys and spleen.
What is a high level of Anticardiolipin?
What does it mean if your Anticardiolipin Ab,IgG,Qn result is too high? Positive and strongly-positive results for IgG and IgM phospholipid (cardiolipin) antibodies (>40 GPL and/or >40 MPL) are diagnostic criteria for antiphospholipid syndrome (APS).
