A white blood cell count of more than 20,000 means that the white blood cell count is greater than 20×10^9/L, which is significantly higher than the normal range of white blood cell count (4~10)×10^9/L. The condition is serious.
Causes that can lead to a white blood cell count greater than 20×10^9/L include serious infections (such as severe pneumonia, etc.), leukemia, and so on, of which serious infections are the most common, so the condition is serious.
1. White blood cells are cells that play an anti-inflammatory role in the body. When bacterial infection occurs in the body (e.g. Streptococcus pneumoniae, etc.), the white blood cell count in the body rises. The higher the white blood cell count is, the severity of the infection is relatively high, and the condition needs to be further evaluated by perfecting the examination of procalcitonin, C-reactive protein, and so on.
2. In the early stage of leukemia, the white blood cell count is in a state of continuous elevation, and it may be greater than 20×10^9/L, but it will rise very quickly in a short period of time, and it is necessary to improve the bone marrow puncture and biopsy and other tests to make a clear diagnosis.
It is recommended that the patient consult a doctor in a timely manner to complete the relevant examinations to determine the cause of the leukocyte elevation, and then under the guidance of the physician to address the cause of the treatment.
