Leukopenia

Leukopenia is a disease caused by unknown causes and secondary to other diseases, and is divided into two categories: primary and secondary. Decreasing the number of white blood cells will weaken the body's antibacterial ability and make it susceptible to infection. However, leukopenia does not have to be treated, one depends on the degree of reduction; the other depends on the cause of the decrease. When the number of white blood cells in peripheral blood continues to be lower than 4x109 / L, they are collectively referred to as leukopenia. If the total number of white blood cells is significantly reduced, less than 2x109 / L, the absolute value of neutrophils is less than 0.5x109 / L, and even those who disappear are called Agranulocytosis.
