Biomarker Reference · aCL IgM
Anticardiolipin Antibody IgM (aCL IgM) is a clinical biomarker used in cardiovascular assessment. The IgM isotype of anticardiolipin antibodies is measured in parallel with IgG, reported in MPL units (IgM phospholipid units). It is measured in 1 laboratory test on BiomarkersLabs.com.
The IgM isotype of anticardiolipin antibodies is measured in parallel with IgG, reported in MPL units (IgM phospholipid units). IgM antibodies can be induced by infection and are often transient, so their clinical significance is lower than that of IgG unless titres are high and persistent.
IgM anticardiolipin at moderate-to-high titre, confirmed on repeat, may contribute to antiphospholipid syndrome diagnosis but is weighted less heavily than IgG or lupus anticoagulant. Isolated IgM positivity without IgG or LA is more likely to be transient or non-pathogenic.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
