Chemiluminescent immunosorbent assay of serum myoglobin based on the luminol reaction.

A simple and sensitive method for the determination of serum myoglobin is described. Myoglobin was determined in the range of 10-500 micrograms/1 by the chemiluminescent luminol reaction after adsorption to anti-myoglobin IgG onto a solid phase. Only 50 microliter of serum has to be used and the luminescent immunoassay (LIA) has a better sensitivity and a wider linear range than the conventional radioimmunoassay (RIA). However, in its present form LIA has a higher imprecision than RIA. In clinical specimens the correlation between the two methods was excellent.
