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.
本文给出了一项血铅测定实验室间能力验证研究的结果。样本取自职业性接触铅的个体。对各实验室在两年期间的表现进行了比较。近年来，对此类能力验证研究的重视程度有所提高，实验室间的一致性有所改善，但血液仍是一种难以测定铅浓度的基质。
