吞噬细胞(主要包括血液中的嗜中性粒细胞,大单核细胞和组织中的巨噬细胞)吞噬作用的检查是非抗原特异性免疫实验中主要的内容之一,也是微生物学教学中学生需要操作的实验。以往是由学生扎自已的手指尖后挤出血液从而获得嗜中性粒细胞,常因扎血技术不熟练而得到的血液较少或取不到血液,难以获得足够的嗜中性粒细胞,所以大多数学生做不出阳性结果。针对这一情况,经摸索,改用医院检验科做试验后的废血代替由指尖取血, Examination of the phagocytosis of phagocytes, including predominantly blood neutrophils, macrophages, and macrophages in tissues, is one of the major aspects of non-antigen-specific immunological experiments and is where microbiology teaching students need to operate experiment of. In the past, students squeezed their own fingers after the tip of the blood to obtain neutrophils, often unsafe due to unsmooth Zhanzhuan technology obtained less blood or blood, difficult to get enough neutrophils, So most students can not make positive results. In response to this situation, after groping, switch to the hospital testing department to do the test after the waste instead of blood from the fingertips,
