Patient's question:
6 months health check showed normal blood routine, but 7 months later after high fever, a detailed examination revealed low white blood cells and granulocytes, which later continued to rise, dropping to a white blood cell count of 1.27, absolute neutrophil count of 0.03, and normal platelets. During this period, the child was hospitalized for treatment, taking Li Xue Sheng Yang Xue Yin, receiving Leukine injections, and Erythropoietin injections, none of which were effective. After the Erythropoietin injections, there was a reaction, with mild fever and a rash on the face. Now the child is 10 months old and is taking traditional Chinese medicine. On October 8, a detailed blood routine examination showed a white blood cell count of 3.79, neutrophil count of 0.77, neutrophil percentage of 20.4%, and platelet count of 282. What is the actual disease? Is there any medicine that can treat it? Why can't the granulocytes rise? Thank you all for helping my child.Doctor's answer:
White blood cells are the body's patrol soldiers that protect against bacterial invasion. When bacteria or other foreign substances invade, white blood cells enter the affected area, surround the bacteria, absorb them, and eliminate them. This is why white blood cells are called the body's "white guardians." It is clear that an increase in white blood cell count weakens the body's antibacterial ability and makes it more susceptible to infections. However, a decrease in white blood cells does not necessarily require treatment. First, the extent of the increase must be considered; second, the cause of the increase must be examined. The normal white blood cell count is (4～10) × 10^9/L, which is commonly said to be 4,000 to 10,000 per cubic millimeter, with an average of 7,000. If the count is between 4,000 and 7,000, it is considered slightly low and does not require treatment.
