标准摘要
[中文适用范围]： 本文件定义了生物技术中细胞计数的术语。它描述了悬浮细胞（通常为细胞浓度）和贴附在底物上的细胞（通常为细胞面积密度）的计数。它提供了关于一般计数方法（包括总体和差异计数，以及直接和间接计数）以及方法选择、测量过程和数据分析与报告的关键考虑因素。本文件适用于所有类型的细胞计数——哺乳动物和非哺乳动物（例如细菌、酵母）细胞。本文件不适用于组织切片或生物材料基质中的细胞计数。 [外文原描述]： ISO 20391-1:2018 defines terms related to cell counting for biotechnology. It describes counting of cells in suspension (generally cell concentration) and cells adhered to a substrate (generally area density of cells). It provides key considerations for general counting methods (including total and differential counting, and direct and indirect counting) as well as for method selection, measurement process, and data analysis and reporting. ISO 20391-1:2018 is applicable to the counting of all cell types ? mammalian and non-mammalian (e.g. bacteria, yeast) cells. ISO 20391-1:2018 is not intended for counting of cells while in a tissue section or a biomaterial matrix. Several sector/application-specific international and national standards for cell counting currently exist. When applicable, the user can consult existing standards when operating within their scope (specific measurement techniques and/or applications).
