Hi, anitajo. Leukemia is very unlikely at this point. Other possible causes are more likely. It could even be from a common virus infection. It's not unusual for people to get terrified when they see results like yours, but it's almost always not-cancer in the end.
Can you give anything more to go on? Why were you at the doctor's to begin with?
Do you have antibodies to the thyroid found on testing?
Or if you have some condition that is something of a mystery, and has been for a while, then you might find that it is difficult to pin down. But still not-cancer.
Usually when people have mystery conditions, they can go years and then find out it is some dysfunction to do with the immune system. The treatment is usually to suppress the immune system, and/or remove whatever might be stirring up the immune system.
So the doc is more or less doing a fishing expedition, which is good and correct. But your neutrophils being somewhat low is not going to cause any alarm in anybody. Besides, in the rare cases where leukemia causes neutrophils to be low it, almost always it causes other blood cells to be low, too. Not just neutrophils alone.
So as for Monday, you can be thinking, "I wonder what mystery the doc will pursue". :) Your family history and your own history of any odd conditions since childhood will be relevant.
