 [ Symptoms ] my sister was diagnosed with acute neutrophilia is this a form of leukemia [ Disease ] on the face of it the answer is no  acute neutrophilia is not leukemia but let me explain further neutrophilia is the medical term for an abundance of normal white blood cells in the system acute simply means the high blood cell count is a short term or temporary event neutrophilia is often called a high white cell count  usually a high white cell count indicates the individual is body is responding to an infection since that is the primary role of white blood cells in the system however any type of inflammation can raise the white cell count including a heart attack or a bad burn in leukemia the bone marrow produces an overabundance of abnormal white cells called leukemia cells these cells are not normal white cells and do not act like normal white cells for example leukemia cells do not fight bacterial infections the way normal white blood cells do if you and your sister are concerned about her diagnosis your best bet is to have a discussion with her health care provider about what her diagnosis means and what may have caused her white blood cell count to go up if this is garden variety neutrophilia the chances are her white count will normalize gradually i hope this helps
