However, because bone marrow puncture can only extract a little bone marrow component in a local area, sometimes it can not reflect the complete picture of bone marrow hematopoiesis, so it should be punctured at multiple sites when necessary. Other a few patients because marrow is fibrotic or cellular component is too much, although puncture of many places for many times also takes out not to give marrow fluid and make puncture failure, also can because puncture technology is not skilled and mix blood to dilute marrow fluid, these problems are solved through marrow biopsy.
