What do you know about Neutropenia?

I was involved in a research study where they took my blood count periodicly through the year. Each time my neutrophil count (part of white blood cells) got lower and lower. He said he hadnt ever seen someone that appears healthy with that low of a count. The dr was amazed that I didnt have reoccuring/unresolved infections and mouth ulcers. He was very concerned and said I should see a hemotologist and get a bone marrow biopsy. (since its unrelated to the study he couldnt help me) I got a new job and insurance is about to kick in...Im pretty nervous about the possibilities.
