Acute granulocytic leukemia m4 bone marrow report, i.e. leukemia bone marrow report, needs to look at items such as bone marrow primitive cell count, significance of granulocyte to young erythrocyte ratio.
1. Bone marrow primitive cell count: Bone marrow primitive cells include primitive red blood cells, primitive granulocytes and primitive megakaryocytes.
Normal value of primitive erythrocytes is <1%, and the increase is mostly seen in acute erythroleukemia. Normal value of primitive granulocytes <2%, increased in acute granulocytic leukemia, acute granulomonocytic leukemia. Normal value of primitive megakaryocytes is 0%~5%, increased in acute megakaryocytic leukemia.
2. The significance of the ratio of granulocytes to young red blood cells
(1) Normal ratio can be seen in normal human bone marrow; it can also be seen in aplastic anemia, myelofibrosis, myeloma, bone marrow metastatic carcinoma and other cases in which the cells of two lineages increase or decrease at the same time or in proportion.
(2) Increased ratio can be seen in acute and chronic granulocytic leukemia, infection, leukemia-like reaction and other cases of increased granulocytes; it can also be seen in pure red cataract and other cases of inhibition of erythropoietic cell production.
(3) Decreased proportions can be seen in cases of granulocytopenia or deficiency, chemotherapy, radiation sickness, and other cases of granulocytopenia.
The rest of the lymphocyte lineage change significance, etc. Therefore, it is recommended that the patient should consult the doctor in time when the bone marrow report is taken to identify the condition and make a clear diagnosis under the doctor’s guidance.
