YR 1965 UL http://pediatrics.aappublications.org/content/35/5/765.abstract AB The depression of a single serum protein, the beta1C globulin (normally 130-155 mg/ 100 ml) to below 80 mg/100 ml is manifested by a decreased hemolytic complement titer. Since this protein can be measured by an immunodiffusion methol, its immunoassay can be used as a substitute for the hemolytic titration of complement in the diagnosis of patients with acute glomerulonephritis, systemic lupus erythematosus, and the nephrotic syndrome. A rapid immunoassay of the serum beta1C globulin can be easily performed.
