Is it normal to have White blood cell count as 21000 per drop?

Answer 1

It is not counted by drop. "Normal range varies slightly between laboratories but is generally between 4,300 and 10,800 cells per cubic millimeter (cmm)."

High "WBC count can be an indicator of a infection, inflammation, or allergy."

Testing needs to be done if high to determine the cause.

Answer 2

White blood corpuscles are about 6k per cubic millimeter, not drop.
