low white cell count

Do I need to be concerned with a reading of 3.5 white blood cell count. I am not on chemo therapy  or any other drug treatment. My doctor has my blood checked every two months to make sure the numbers do not keep dropping. If they drop to the 2's she wants to do a bone marrow biopsy. I say my reading are normal for me am I in denial. Please expland.. I have done research on the topic with not satisfying answers.

Hi there,
A low WBC count can be a symptom of a number of diseases like aplastic anemia, vitamin deficiencies, parasitic infestations, lupus or liver disease, HIV, or can be among the effects of radiation therapy. A low white blood cell count increases the risk of contracting infections. A bone marrow examination and biopsy is necessary for diagnosing your illness. Get it done. Do write to me again on how you are doing.
Best of luck!
