How many high white blood cells to suspect leukemia

The white blood cells in leukemia can be increased, normal or decreased.
According to the degree of differentiation and maturation of leukemia cells and the natural course of the disease, leukemia can be divided into two major categories: acute and chronic. The majority of patients with acute leukemia have increased white blood cells, as well as normal or decreased white blood cells, and laboratory tests also show varying numbers of primitive and naïve cells, as well as varying degrees of anemia.
Patients with chronic leukemia have significantly elevated white blood cells, often greater than 20 × 10⁹ / L, and laboratory examination of granulocytes increased significantly to neutral neutrophilic, late juvenile, and rod-shaped nucleated granulocytes are predominant.
Leukemia cannot be diagnosed by leukocyte test alone, but also by bone puncture, immunology, cytochemistry, cytogenetics and molecular biology.
If you find abnormal white blood cells, it is recommended that you go to a regular hospital in a timely manner to have the relevant tests clarified and then targeted treatment.
