I had a routine blood test this week at my doctors and my WBC has doubled from 25.1 to 51.7. I live in Greece and my Hematologist is in Athens (240km) from me - also her English is not the best. I was diagnosed in 2010 with a WBC of 9.3 and since then the figure has increased slowly. I saw a doctor today at my local health centre who told me that the other figures on the Blood Test do not vary much from my last on in March - except for the WBC. Can someone give me some advice on what I should do. Should I contact my Haematologist and see what she says?
