Quantitation of serum immunoglobulins by three different methods.
Immunoglobulins were quantitatively determined on 21 serum samples by radial immunodiffusion, nephelometry and immunofluorescence. Good correlations were obtained with all three different methods in regard to IgG and IgA. IgM values were about 40% higher with radial immunodiffusion than with the other two methods.
