Intended Use

An IgM test system is a device intended for the quantitative in vitro determination of IgM in serum and plasma. This product is suitable for use on RX series analyser RX modena.

Clinical Significance

IgM constitutes about 6% of the total immunoglobulin concentration in serum and has functions similar to that of IgG. The Primary functions of IgM in the immune response are the agglutination of pathogens and the activation of the classical complement pathway.

Measurement of IgM therefore aids in the diagnosis of abnormal protein metabolism and the body’s lack of ability to resist infectious agents.


Sample containing human IgM is suitably diluted and then reacted with specific antiserum to form a precipitate which is measured turbidimetrically at 340 nm. By constructing a standard curve from the absorbances of standards, the IgM concentration of sample can be determined.
