What is a dangerous white blood cell count?
The exact threshold for a high white blood cell count varies from one laboratory to another. In general, for adults a count of more than 11,000 white blood cells (leukocytes) in a microliter of blood is considered a high white blood cell count.
What is a dangerously low white blood cell count?
A blood test that shows a WBC count of less than 4,000 per microliter (some labs say less than 4,500) could mean your body may not be able to fight infection the way it should. A low number is sometimes called leukopenia.
