Fun with graphs

We are looking at a graph from my last blood test. An eosinophil is a type of white blood cell.If a normal range of eosinophils in a body is from 0-4%, and I'm at 12%, wouldn't you think there was something wrong?Not so, says Super Awesome Nurse (who is always there to calm my hypochondria). She says it is only an issue if my complete blood panel showed inconsistencies. But my the rest of my blood work looks normal.
