What is IgM assay used for?
IgM measurement has the following uses: to establish diagnosis and monitor therapy in Waldenström’s macroglobulinemia and plasma cell myeloma, to detect intra-uterine infection by measuring levels in new born babies, diagnosis of primary biliary cirrhosis, viral hepatitis, rheumatoid arthritis and parasitic infections.
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 a sample can be determined.
