Beta-2-glycoprotein-I antibodies (IgG)
Beta-2-glycoprotein IgG antibodies (code B2GLPG serum) are part of the diagnostic criteria for determining APS (antiphospholipid syndrome). This blood test has a higher specificity but lower sensitivity than Cardiolipin antibodies. Its detection is associated with the occurrence of arterial and venous thrombosis and with miscarriages. According to the classification criteria of the antiphospholipid syndrome, a positive result should be confirmed by a second determination after 12 weeks.
IgG result:
| negative | <10 U / ml |
| borderline | 10-40 U / ml |
| positive | > 40 U / ml |
| method: | Fluorescence enzyme immunoassay (FEIA) |
