Luuüdi äige ja luuüdi biopsia nõel

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 all kinds of leukemia. The proliferation of nucleated cells in bone marrow tablets was observed at low magnification by selecting the part with uniform cell distribution, and 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 young red blood cells according to the classification of 100 white blood cells in the number of young red blood cells to report, and explain its stage nucleated cell classification count; Calculate the grain and red ratio; Observe whether there are other special cells and parasites.

Luuüdi biopsia või luuüdi biopsia puhul võetakse spetsiaalse nõela abil patoloogiliseks uuringuks väike, umbes 0,5–1 sentimeetri pikkune silindriline luuüdi tükk. Operatsioonimeetod on täpselt sama, mis luuüdi biopsia puhul. Eemaldatud materjal säilitab kogu luuüdi koe struktuuri, mis võib korvata luuüdi punktsiooni puudujäägi. See mitte ainult ei mõista luuüdi rakkude koostist ja algsete rakkude jaotumist, vaid jälgib ka rakkude morfoloogiat, mis on mugav patoloogilise diagnoosi tegemiseks, aplastilise aneemia diagnoosimiseks, luuüdi düsplaasia
