title: Reference intervals for serum IgG, IgA, IgM, C3, and C4 as determined by rate nephelometry.
abstract: We report reference intervals for IgG, IgA, IgM, C3, and C4 for a population of 750 well children and 120 healthy adults. Ranges were established by rate nephelometry (previous studies have been based on immunodiffusion). Our results generally agree with previously established immunoglobulin ranges, except for some disagreement as to ages when adult values are attained.
