MORE INFO:
Normally the total WBC count for an adult ranges from 5,000 to 10,000/mm3. Leukocytosis (WBC>10,000/mm3) can indicate infection, inflammation (possibly from allergies), tissue damage or burns, dehydration, thyroid storm, leukemia, stress, or steroid use.
The mean normal platelet count is between 250,000 and 260,000 cells/mm3, although there is a wide range of accepted normal values in most laboratories that extend as low as 150,000 to as high as 400,000/mm3.
