The total number of peripheral blood leukocytes in a normal person is (4.0 to 10.0)x10^/L, which can fluctuate up and down within a certain range depending on the time of day and the functional state of the organism. If it reaches 251, which equates to more than 20 times the upper limit of normal, it can be said to be potentially dangerous.
White blood cells by type include granulocytes, monocytes, and lymphocytes, and granulocytes include neutrophils, eosinophils, and basophils, with the largest percentage being neutrophils. If neutrophilia is seen in acute infectious disease, severe tissue damage, malignancy, etc., but when the total number of leukocytes reaches tens or hundreds of thousands, it is not a normal infection and is commonly seen in leukemia, myeloproliferative disease, etc.
In acute or chronic granulocytic leukemia, the increased number is accompanied by changes in the quality of cells in the peripheral blood. The cause of the disease is not the same, except for the common feature of increased white blood cell count, clinical manifestations vary, so regardless of the total number of increased white blood cells, as long as there are abnormalities, it is best to do further tests and take appropriate therapeutic measures in a timely manner, if the cause is still not exact, then symptomatic treatment and continued observation is appropriate. The results of this study are not only the results of the study, but also the results of the study.
