Quality assurance is essential in laboratory medicine; an important component is external quality assessment in order to ensure that reliable performance is achieved by all laboratories and that between-laboratory comparability is maintained. In a number of countries there are national external quality assessment schemes. WHO has established a programme aimed at encouraging the organization of similar schemes in all countries. Towards this goal an international external quality assessment scheme has been established for each of the specialities of haematology, clinical chemistry, microbiology and parasitology.This paper describes the organization of the international scheme for haematology. There are now 62 laboratories taking part in 49 countries. The functioning of the scheme, the participants' response, and the extent to which the scheme has improved the standard of practice in their laboratories are described.
质量保证在检验医学中至关重要；一个重要组成部分是外部质量评估，以确保所有实验室都能实现可靠的性能，并保持实验室间的可比性。在许多国家都有国家外部质量评估计划。世界卫生组织已制定了一项计划，旨在鼓励各国组织类似的计划。为实现这一目标，已针对血液学、临床化学、微生物学和寄生虫学等每个专业建立了国际外部质量评估计划。本文描述了血液学国际计划的组织情况。目前有来自49个国家的62个实验室参与其中。文中还描述了该计划的运作情况、参与者的反馈，以及该计划在多大程度上提高了他们实验室的实践标准。
