Interlaboratory comparison of blood lead determinations.
Results are presented for an interlaboratory proficiency study of blood lead determinations. Samples were pooled from individuals occupationally exposed to lead. Performance of individual laboratories is compared over a two year period. With increased emphasis in recent years on proficiency studies of this type, agreement between laboratories has been somewhat improved, but blood remains a difficult matrix in which to measure lead concentration.
