能力验证(proficiency testing)即利用实验室间比对,按照预先制定的准则评价参加者的能力[1]。通过能力验证能够评定实验室从事特定检测或测量的能力,识别实验室存在的问题并启动改进措施,提高实验室的检测能力等。因此,参加能力验证活动对实验室质量控制有着非常重要的意义。上海市闸北区疾病预防控制中心实验室已连续多年参加辽宁出入境检验检疫局食品微生物能力验证计划,现将从中收 Proficiency testing is the use of inter-laboratory comparisons to evaluate participants’ ability according to pre-established guidelines [1].
