增生正常或增生活跃的骨髓片与血片的区分,当然是非常容易的。但是再生障碍性贫血患者的骨髓要与血液区分,就要有一定的实践经验,否则本来抽出的是骨髓,也没有被血液所稀释,往往错误的以“取材不满意”(指有核细胞与血片相似,怀疑取材不是骨髓)而造成病人需重作骨穿的痛苦。 Differentiation between normal and hyperplastic bone marrow slices and blood films is of course very easy. However, patients with aplastic anemia of bone marrow and blood must have some practical experience, or had been extracted from the bone marrow has not been diluted by the blood, often wrong to “not satisfied” (referring to nucleated cells and Blood film is similar, suspected of not drawing bone marrow) and cause the patient to be re-bone pain.
