Pediatric pseudoneutropenia

Pseudoneutropenia is caused by the abnormal distribution of granulocytes. The fluctuation range of granulocytes in the blood around the patient is large and changes rapidly. Those without primary disease and repeated infection can be collectively referred to as benign granulocytopenia. Includes familial, congenital, and pseudoneutropenia. There was an intermittent attack, the granulocytes were moderately reduced, and the process was good. When the blood flow is slowed down, granulocytes tend to attach to the walls of small blood vessels, causing granulocytes in the marginal pool to increase. After epinephrine injection, granulocytes can rise to normal or 1 to 2 times before the test, which can be used as a basis for diagnosis of this disease.
