A white blood cell 40+ means that the condition is serious with a white blood cell count of (40~50) x 10^9/L.
The normal range of white blood cell count for normal people is (4~10)×10^9/L. A white blood cell count of (40~50)×10^9/L belongs to a very high level, which may be a manifestation of severe inflammation or leukemia, so the patient’s condition is serious.
1. In case of inflammation leading to a white blood cell count of (40~50)×10^9/L, it is likely that the organism has undergone the manifestation of sepsis, which may even lead to the occurrence of infectious shock. Calcitoninogen, C-reactive protein and other inflammatory indicators are also often significantly elevated in such patients, need to immediately select sensitive antibiotics and active anti-infective treatment, drugs include imipenem and so on.
2. When acute leukemia or chronic granulocytic leukemia or chronic lymphocytic leukemia occurs, the white blood cell count can be up to (40~50)×10^9/L in the process of disease development, and it is persistently increased, which may be accompanied by anemia and/or decreased platelet count. Bone marrow aspiration and biopsy can be used to confirm the diagnosis.
It is recommended that the patient consult a doctor in time to identify the cause of the disease and then actively treat the cause under the guidance of the physician.
