Beta 2 glycoprotein normal range
Protein c and s deficiency – causes, symptoms, diagnosis
Anticardiolipin (aCL) antibodies and anti-beta(2)-glycoprotein 1 (anti-beta(2)GP1) immunoglobulin G and IgM immunoglobulin G and IgM immunoglobulin G and IgM immunoglobulin G and IgM immunoglobulin G and IgM immunoglobulin G and IgM immunoglobulin G and IgM immunoglobulin G and IgM immunoglobulin G and IgM immuno Commercial ELISA kits were used to detect aCL IgG and IgM separately. Anti-beta(2)GP1 antibodies were identified using beta(2)GP1 in an in-house ELISA.
Seven patients were found to have APS, while 184 were found to have other illnesses. Thirty-six patients tested positive for aCL, and 12 tested positive for anti-beta(2)GP1, seven of which were APS patients. In our population, anti-beta(2)GP1 had a 97 percent specificity and a 58 percent positive predictive value (PPV). Specificity was 90% and PPV was 70-87 percent among aCL-positive patients.
Anti-beta(2)GP1 antibodies have a higher specificity and PPV for APS than aCL, according to this report. Anti-beta(2)GP1 had a higher PPV in aCL-positive patients than in all other patients. We conclude that screening for anti-beta(2)GP1 antibodies in aCL-positive patients improves aCL testing’s specificity and PPV. In addition, we show that in the absence of aCL antibodies and a clear clinical suspicion of APS, there is no need to test for anti-beta(2)GP1 antibodies.

The clinical signs of APS do not provide enough information to make a definitive diagnosis. As a result, laboratory tests are crucial in the diagnosis of the disease. Autoantibodies are produced in APS patients that bind to phospholipids such as cardiolipin or phospholipid-binding proteins such as beta-2-glycoprotein. The detection of these autoantibodies is a requirement of the International Society on Thrombosis and Hemostasis’ classification criteria.
Antibodies to beta-2-GPI have been linked to arterial and venous thrombosis, as well as recurrent miscarriage. Beta-2-GPI antibodies are thought to have a higher specificity for detecting APS than cardiolipin antibodies; they can be detected even if the cardiolipin test is negative.
Anti-beta-2-Glycoprotein I Screen is an ELISA-based test for quantifying antibodies to beta-2-glycoprotein I in human serum or plasma. This test looks for antibodies to IgA, IgM, and IgG at the same time.

The antiphospholipid syndrome (APS) is an autoimmune disorder marked by a procoagulant state that puts the patient at risk of recurrent thrombosis and miscarriage. Two significant breakthroughs have improved our understanding of the APS’s underlying complex pathogenesis. The first was the discovery that the main auto antigen in APS is beta-2 glycoprotein-1 (2GPI). The second was the recent discovery that 2GPI contains allosteric disulphide bonds that are susceptible to posttranslational alteration and which play a role in the formation of autoantibodies in APS. In the fifth domain of 2GPI, the main allosteric disulphide bond may be in one of two redox states: free thiol or oxidized. The exposure of neo-epitopes on the first and fifth domains is due to the conformational transformation of 2GPI from its free thiol form to its more immunogenic oxidised form. The aim of this review is to highlight recent research on the role of 2GPI posttranslational forms in the pathogenesis of APS. We believe that novel assays that measure the different redox types of 2GPI in plasma or serum may be used to complement current clinical and laboratory assays to better stratify the risk of thrombosis or miscarriage in APS patients.
