Why Bone Marrow Aspirate

Mar 14, 2022

Bone marrow aspirate is a commonly used clinical diagnosis and treatment technique. The cytomorphological examination of bone marrow aspirate smear can diagnose certain hematopoietic and non-hematopoietic diseases, and has important differential diagnosis value for certain diseases. It is simple to operate, the whole process is fast, the patient suffers little, and there is no damage to the human body. After the operation, it can move freely without affecting normal life. Clinically, the morphological examination of bone marrow cells is mainly used for the following aspects: 1. Diagnosis of certain diseases, mainly hematopoietic system diseases. For example, leukemia, multiple myeloma, aplastic anemia, megaloblastic anemia, typical iron deficiency anemia, bone marrow metastases, etc. 2. Auxiliary diagnosis of certain diseases. Such as hemolytic anemia, idiopathic thrombocytopenic purpura, hypersplenism and so on. These diseases are also mainly diseases with changes in bone marrow hematopoietic function, but they cannot be diagnosed by a single bone marrow cell morphological examination, and comprehensive analysis is required in combination with other clinical data. 3. Differential diagnosis of certain diseases. For example, long-term unexplained fever, cachexia, liver, spleen, lymph node enlargement, etc., bone marrow examination can help to identify the cause of the disease. 4. Observe the treatment effect and progress of the disease. Dynamic understanding of bone marrow hematopoiesis can better determine the development of the disease and adjust the treatment plan. Finally, it is worth noting that bone marrow aspirate should not be performed in patients with severe bleeding tendency due to coagulation factor deficiency (eg, in patients with hemophilia).
