IgM at

PRINCIPLE

IgM at is a quantitative turbidimetric assay for the measurement of IgM in human serum or plasma.

Anti-human IgM antibodies form insoluble complexes when mixed with samples containing IgM. The scattering light of the immunocomplexes depends of the IgM concentration in the patient  sample, and can be quantified by comparison from a calibrator of known IgM concentration.
