title: [Serum IgD concentrations in normal individuals 20-39 years of age].
abstract: Immunoglobulin D(IgD) concentration in serum of normal individuals varies widely, and the reference interval for the concentrations remains to be defined. In the present study, IgD concentrations were determined in serum from 637 normal individuals 20-39 years of age by the latex nephelometric immunoassay. The IgD concentrations ranged from < 0.20 to 71.5mg per deciliter, and the median and the 95% range as reference intervals were 1.99 and < 0.20 to 17.3mg/dl, respectively. There was difference of serum IgD concentration between female 20-29 years of age and female 30-39 years of age (p < 0.05), but not on sex. The correlation between serum IgD concentration and serum IgA concentration was significant (p < 0.001).
