Anti-Cardiolipin IgM
Anti-cardiolipin IgM completes the antiphospholipid antibody panel for comprehensive APS risk assessment.
Doctor's Assessment Included
Anti-Cardiolipin IgM: what this test measures
This test quantifies IgM antibodies directed against cardiolipin. Results are reported in MPL units.
Anti-Cardiolipin IgM: why this value matters
Anti-cardiolipin IgM completes the antiphospholipid antibody profile. Isolated IgM positivity is less specific for APS and may occur transiently with infections, but persistent positivity contributes to APS diagnosis.
Anti-Cardiolipin IgM: when is testing worthwhile?
Testing is typically ordered alongside anti-cardiolipin IgG and lupus anticoagulant as part of a complete APS evaluation.
Anti-Cardiolipin IgM: symptoms of a high or low value
Low Levels
A negative result is normal. In the absence of other positive antiphospholipid antibodies, no follow-up is required.
High Levels
Elevated anti-cardiolipin IgM may contribute to APS diagnosis when persistent and combined with clinical criteria. Isolated IgM elevation is less predictive of thrombosis than IgG.
Anti-Cardiolipin IgM: lifestyle and this value
The same recommendations as for anti-cardiolipin IgG apply. If APS is confirmed, long-term anticoagulation and specialist follow-up are typically recommended.
Anti-Cardiolipin IgM: frequently asked questions
Is IgM less important than IgG?
Can infections cause false-positive IgM?
Do I need all three tests for APS diagnosis?
