Bone Marrow Cell Smear And Bone Marrow Biopsy Needle

Bone marrow smear is used to determine the degree of nucleated cell hyperplasia. Iron staining and different histochemical staining of bone marrow smear can provide diagnostic basis for iron deficiency anemia and various leukemia. The proliferation of nucleated cells in bone marrow tablets was observed at the site of uniform cell distribution at low magnification. The proliferation degree of nucleated cells was estimated according to the density of nucleated cells or the ratio of nucleated cells to mature red blood cells in bone marrow tablets. Classify and count 100-200 white blood cells, calculate the percentage of all kinds of white blood cells, and describe the red blood cell morphology, platelet number and distribution. If you see the number of young red blood cells according to the classification of 100 white blood cells to report, and explain its phase nucleated cell classification count; Calculate grain and red ratio; Observe whether there are other special cells and parasites.
A bone marrow biopsy, or a bone marrow biopsy, uses a special puncture needle to take a small cylindrical piece of bone marrow about 0.5 to 1 centimeter long for pathological examination. The operation method is exactly the same as that of bone marrow puncture. The material removed maintains the complete bone marrow tissue structure, which can make up for the deficiency of bone marrow puncture. It can not only understand the composition of bone marrow cells and the distribution of original cells, but also observe cell morphology, which is convenient for pathological diagnosis and diagnosis of aplastic anemia and bone marrow dysplasia
