What Causes Elevated Levels Of Immature Granulocytes?

I just had a my annual physical. The Immature granulocytes reading was 2. The chart showed references 0-1. I a very healthy eighty -five year old who has no organ or blood problems. My doctor did not say a change about my number. what I just read about this subject is causing concern. Please tell if I should do something about this situation. Thank you! Robert Stanton
