Ray,
How long has your ANC been elevated? Is it up or down compared to last time?
From what I've read, this condition is called neutrophilic leukocytosis and isn't itself harmful, but is a symptom of an underlying issue, such as an infection, inflammation, tissue damage, or trauma. I hope that your doctor's inattention to your high ANC is a sign that it's not a concern for you, but I haven't heard mention of this situation before.
Possible causes mentioned for neutrophilic leukocytosis are infections, inflammation, tissue damage, and trauma, but when you've had a transplant the explanation could clearly be different.
And here's something ironic: For people with chronic neutrophilic leukocytosis, one of the possible treatments is a bone marrow transplant (see
article)!
