Here is My Question:
My white blood cell count is 300 and my lymphocyte count is between 800 - 900. Is this OK?
Whether this is okay depends on other conditions you have and treatments you’ve received. The majority of the time counts in this range in most people with MS on a Disease Modifying Therapy (DMT) are entirely expected and no reason to worry.
Many of the DMTs, such as all the interferons (i.e. Avonex, Betaseron, Rebif, Extavia) and Tecfidera, will lower white blood counts in this range. Gilenya will often lower WBCs much more than this amount. Copaxone rarely decreases WBCs and Tysabri will increase WBCs.
