People with neutropenia have an unusually low number of cells called neutrophils. Neutrophils are cells in your immune system that attack bacteria and other organisms when they invade your body.
Neutrophils are a type of white blood cell. Your bone marrow creates these cells. They then travel in your bloodstream and move to areas of infection. They release chemicals to kill invading microorganisms.
Call 911 for immediate emergency medical help if you have any of these symptoms:
Lengthy, uncontrollable bleeding -- either heavy or oozing in nature -- particularly after injury, immunizations or surgical or dental procedures. Seek emergency medical help for any heavy or uncontrolled bleeding.
Any signs of internal bleeding, such as a change in consciousness, alertness, or memory or difficulty breathing (note that these symptoms may also be signs of other medical problems unrelated to hemophilia).
Call your doctor if you notice any of these symptoms:
Any episode of bleeding unrelated to a particular injury or event
Pain, swelling, warmth, or redness in a joint or muscle
Also call your doctor if you are parents who have a family history of hemophilia and are expecting a baby.
