Most clinical laboratories participate in surveys of external quality assurance (EQA). The results are not, however, very commonly or effectively applied to controlling the accuracy, i.e., differences in the analytical level. Therefore, it is important that each laboratory has its own, valid reference values. Nevertheless, many laboratories do not follow the internationally accepted recommendations for determining reference intervals or use reference values from other laboratories or from literature. Techniques of the external quality assurance can be extended to the checking of the validity of reference limits.
大多数临床实验室都参与外部质量保证（EQA）调查。然而，这些结果并不常被有效地用于控制准确性，即在分析水平上的差异。因此，每个实验室拥有自己有效的参考值很重要。尽管如此，许多实验室并未遵循国际公认的确定参考区间的建议，或者使用其他实验室或文献中的参考值。外部质量保证技术可以扩展到对参考限有效性的检查。
