The distribution of blood cells in the bone marrow of healthy adults at different stages of development is highly variable, and a normal bone marrow picture is likely if the following conditions are met.
Operation method
Normal Bone Marrow Imaging Assay
Principle
The distribution of blood cells in the bone marrow of healthy adults at different stages of development is highly variable, and a normal bone marrow picture is likely if the following conditions are met. Move l. Active myeloproliferative M:E 2-4:1 For more product details, please visit Aladdin Scientific website.
2. The granulocyte lineage accounts for 50-60% of the nucleated cells. Primary granulocytes <2%, early juvenile granulocytes <5%, middle and late juvenile granulocytes gradually more, but not more than 15% (refers to neutrophils) of mature granulocytes rod-shaped nuclei more than lobulated nuclei, the ratio of the two ≥ 2:l (refers to neutrophils) eosinophils <5% basophils <1%.
3. Infantile erythrocytes accounted for 2O% of the nucleated cells, of which primitive erythrocytes <1%, early erythrocytes <5%, from which late erythrocytes predominated, each accounting for 10% of the nucleated cells. Late erythrocytes mainly accounted for about 10% each, no giant erythrocytes, mature erythrocytes with normal morphology.
4. monocytes, plasma cells <4% each, all mature cells.
5. the count of megakaryocytes is 7-35 in 1.5×3cm bone marrow membrane, more than half of them are platelet-producing type, and platelets are distributed in clusters.
6. A small number of non-hematopoietic cells can be seen, such as reticulocytes. Endothelial cells. Tissue basophils, etc.
7. Nuclear schizophrenia is rare or absent.
8. blood cells of all lineages are generally normal in morphology.
9. Parasites, tumor cells and other pathological cells are not detected.
