Puncture examination is one of the important test methods for hematological diseases. Through the cytological examination of bone marrow smear, we can understand the formation of various cells in the bone marrow, the morphology of various cells, the change of the composition and the discovery of abnormal cells, so as to clarify the diagnosis, observe the curative effect and estimate the prognosis. For example, the diagnosis of anemia can help diagnose the causes of anemia from a morphological perspective, such as iron deficiency anemia, hemolytic anemia, aplastic anemia, and diagnose various types of leukemia; In terms of malignant tumors, bone penetration is of great significance in the diagnosis of multiple myeloma, bone marrow metastasis, and lymphoma invading the bone marrow.
