Anemia patients need to find the cause of the disease, and bone marrow cells can be clearly seen by bone puncture, which can help to clarify the condition and find the cause of the disease. 1. Anemia is a clinical manifestation of the blood system, and the treatment of patients with anemia usually needs to find the cause of the disease and then carry out targeted treatment. 2. Under normal circumstances, patients will first undergo routine blood tests and other related examinations. If it is found that the hemoglobin of the patient is significantly lower than the normal value, it is necessary to carry out further tests such as anemia triple test and iron triple test in order to clarify the cause of the disease. 3. If the routine examination fails to identify the cause of the disease, the patient will need to undergo bone marrow aspiration to take samples for examination. For example, patients with common leukemia need to undergo bone marrow aspiration to determine whether there are progenitor cells. To summarize, it is recommended that patients actively cooperate with the doctor’s examination in order to identify the cause of the disease and treat it as soon as possible.
