What Are Bone Marrow Cells?

Due to physiological variation and different survey data, the ratio of cells in normal bone marrow images at various stages of each system varies widely, so the actual meaning of normal bone marrow images is normal range bone marrow images. The decline data can be used as the normal value of various blood cells in bone marrow smears Reference: The granulocyte system accounts for the largest proportion, about 1/2. Generally, primordial granulocytes are less than 0.02, and promyelocytic cells are less than 0.05, and most of them are neutrophils. Their ratio is greater than that of lobulated nucleus cells and more than late promyelocytic cells. <0.01.

Bone marrow cells

Normal due to physiological variation and different survey data

Due to physiological variations and different survey data, the range of the cell ratio of normal bone marrow image in each stage of each system varies widely, so the normal meaning of normal bone marrow image is the normal range bone marrow image. The decline data can be used as the normal value of various blood cells in the bone marrow smear. reference:

Granulocyte system accounts for the largest proportion, about 1/2 strong. Generally, primordial granulocytes are <0.02, promyelocytic cells are <0.05, and most of them are neutrophils. Their ratio is greater than that of lobulated nucleus cells and more than late myeloid cells. Eosinophils are <0.05 and basophils <0.01.

Bone marrow morphological diagnosis must be combined with clinical examinations, such as whether the liver, spleen, and lymph nodes are enlarged and peripheral blood signs. The diseases with a positive diagnostic value are as follows:

Megaloblastic anemia, various types of leukemia, multiple myeloma Niemann-Pick's disease, Hodgkin's disease, Gaucher's disease, malaria, black fever, cancer metastasis, etc.
