4B00.10/D72.0 Constitutional neutrophilia



Constitutional neutrophilia is a condition in which there is an increase in the number of neutrophils in the blood. This increase can be caused by a variety of factors including chronic infections, certain medications, and certain types of cancer.


The diagnosis of constitutional neutrophilia is typically made by a blood test which measures the number of neutrophils in the blood. The normal range for neutrophils is between 2.5 and 7.5 x 109/L.

Differential diagnosis

Other conditions that can cause an increase in the number of neutrophils in the blood include viral infections, autoimmune diseases, and certain types of leukemia.


The treatment for constitutional neutrophilia depends on the underlying cause. If the cause is an infection or a medication, then the infection should be treated and the medication should be stopped. If the cause is a cancer, then the cancer should be treated.


The prognosis for constitutional neutrophilia is generally good. Most cases can be resolved with treatment of the underlying cause.
