Is a 21000 white blood cell count high for a nine year old?

Answer 1

we need units. 21000 in the entire body means a lot from 21000 per ml. The differential is more useful in identifying why the white cell count is unusual. You need to know what the percentage lymphocytes , neutrophils, monoytes, eosinophils, basophils etc. Also any microscopic observations on the white blood cells.

You are best asking your doctor, as you require far more information than you have given I'm afraid.

Answer 2

White blood cell count (WBC). The number of white blood cells in a volume of blood. Normal range varies slightly between laboratories but is generally between 4,300 and 10,800 cells per cubic millimeter (cmm). This can also be referred to as the leukocyte count and can be expressed in international units as 4.3 - 10.8 x 109 cells per liter.
