The susceptibility to infection is related to the level of neutrophil count.
Peripheral blood neutrophils (x 10^9/l)
The effects of neutropaenia are not consistent and depend upon factors such as the degree and duration of neutropaenia, underlying cause; host defences, general physical state, integrity of skin and mucous membranes, bone-marrow's capacity to respond to infection, previous antimicrobial therapy.
Patients with neutropaenia secondary to a failure of production are at greater risk of infective complications than those in whom there is neutrophil destruction.
