I am a 40 Yr old female who tends to have a low WBC count. I had a routine check up 1 month ago and my CBC showed neutropenia (ANC 1150). I was shocked since I feel great! How common is it to have idiopathic neutropenia? My doc says that s just the way I am. I had a bone marrow bx and it was normal. I hardly ever get sick and have kids in preschool! It seems that my WBC count just goes up and down. What do you think? I ve also been tested for autoimmune disease and I was neg for anti- neutrophilic abs as well as ANA. Thoughts?
