Diagnose leukaemia why do bone marrow puncture needle check

Bone marrow aspiration is the most common and effective way to diagnose leukemia. Leukemia is the "birthplace" of leukemia. Cytological examination based on bone marrow aspiration is used to diagnose and observe white blood malignancies. Although leukemia cells can spread to blood and other organs, only peripheral blood examination (such as venous blood) often cannot accurately reflect the pathological status of leukemia. Marrow disease condition changes, understand the curative effect of accurate and reliable method. Bone marrow smear microscopy showed that leukemia cells had common morphological characteristics: different sizes, increased volume of most of them, increased nucleo-plasma ratio, irregular and often irregular nuclei, rough and uneven distribution of nuclear chromatin, and larger and more significant nucleoli than normal primitive cells. At the first diagnosis of acute leukemia, the vast majority of bone marrow was hyperactive, obviously active or hyperactive, and the normal hematopoietic cells were significantly inhibited. Bone marrow aspiration is not only an effective way to diagnose leukemia, but also an important basis for the classification of leukemia. In the course of treatment, multiple bone marrow aspiration is needed to understand the therapeutic effect and hematopoietic function of bone marrow. Even if the disease has achieved complete remission after treatment, regular examination is needed to detect the recurrence of leukemia early and timely treatment. The method of bone marrow examination is simple, usually in the upper posterior iliac bone or sternum, local injection of a small amount of anesthetics, with bone marrow puncture needle suction of a small drop of bone marrow blood can be done, the operation is safe, and there is no damage to health. Patients should actively cooperate with doctors for bone marrow examination.
