Leukocytes 14.8 x 10⁹/L are classified as elevated white blood cells, most commonly due to infection, not necessarily leukemia. Clinically, the normal range of white blood cells is (4~10) x 10⁹/L, and more than 10 x 10⁹/L can be called elevated white blood cells, and the most common problem is usually elevated white blood cells caused by infection. If you want to determine that it is leukemia, this test alone is not enough. 1. Clinical factors such as acute infection, acute hemorrhage, severe trauma, leukemia and other factors can cause elevated white blood cells, which need to be combined with the patient’s specific clinical manifestations of the corresponding auxiliary examination to confirm the diagnosis. 2. To determine whether it is leukemia, it is also necessary to carry out bone marrow aspiration pathology examination, simple blood routine results can not be a clear diagnosis. In summary, white blood cells 14.8 × 10⁹ / L can not be immediately diagnosed as leukemia, such a situation, please consult a regular hospital in a timely manner, under the guidance of physicians to identify the causes.
