It could be some serious process causing abnormally high production of white blood cells in a bone marrow.
Also, due to an immune system disorder the white blood cells count increases.
High levels of white cells could result from a infection (fighting one, for ex.gastrointestinal, which can also lead to high serum levels of folate)

What was the outcome to this? i have just had the same results, also with a low RBC and low Lymphocytes?

i have infection like cough and high white cell and what medicine pedicilone its ok or not
