This definition can be applied for all ages and races, although it is known that neonates, for example have Increase in the number of granulocytes during the first few days of life and some populations of blacks and Jews usually have low granulocyte numbers.
The peripheral blood neutrophil has a short life of approximately 10 hours, with a life 1/2 of 6.5 hours. It is distributed in two pools: one circulating, and one marginal at the tissue level. The progenitor cell of the mature neutrophil is the colony-forming unit of granulocytes and macrophages.
The susceptibility to infections in neutropenic patients depends on the RAN (Absolute Neutrophil Count). (% Bands +% mature neutrophils) x 0.01 In turn, the more severe the neutropenia and the longer the duration, the greater the chance of infection.
Which can occur are. Decreased production at the level of the bone marrow. Displacement from the peripheral circulation to the tissues. Destruction at the peripheral level. Combination of any of the above
