Quality control (QC) has been introduced in laboratories, and QC surveys in leukocyte differential count to enhance quality have been performed by College of American Pathologists, Japanese Association of Medical Technologists, Osaka Medical Association and manufacturers. The results of QC survey in a manual leukocyte differential count indicated problems on the differentiation of segmented neutrophils and band neutrophils and the detection of pathological blood cells on blood smear. While the results of QC survey in an automated leukocyte differential count performed by same manufacturer with an automated blood cell counter were satisfactory, however, there was a difference in leukocyte differential cell counts among laboratories with other manufacturer's instruments because the synthetic blood material used in QC is an exclusive item for an instrument. It is necessary to further reeducate the medical technologists in order to improve morphological performance, and to standardize the synthetic blood material for compatibility with various automated blood cell counters.
实验室已引入质量控制(QC),美国病理学家学会、日本医学技术人员协会、大阪医学协会及制造商已开展白细胞分类计数的质量控制调查以提高质量。手工白细胞分类计数的质量控制调查结果表明,在区分分叶核中性粒细胞和杆状核中性粒细胞以及检测血涂片上的病理性血细胞方面存在问题。虽然同一制造商使用自动血细胞计数器进行的自动白细胞分类计数的质量控制调查结果令人满意,但是,由于质量控制中使用的合成血液材料是某一仪器的专用物品,使用其他制造商仪器的实验室之间白细胞分类细胞计数存在差异。有必要进一步对医学技术人员进行再培训,以提高形态学表现,并使合成血液材料标准化,以便与各种自动血细胞计数器兼容。
