Quantitative immunoglobulin levels (IgG, IgA and IgM) in children, determined by the Hyland Immunoplate technique.
Quantitative immunoglobulin levels (IgG, IgA and IgM) were determined in 200 infants and children ranging in age from 2 months to 15 years, using the Hyland "Immunoplate" technique. The mean values obtained ranged from 346 mg. % for IgG in the youngest age group to 814 mg. % in the oldest; for IgA the mean values ranged from 49 mg. % in the youngest age group to 114 mg. % in the oldest; for IgM the mean values ranged from 47 mg. % in the youngest age group to 97 mg. % in the oldest age group. The method used proved to be reproducible from day to day and was much more rapid than a previously used double-diffusion technique.
