My wbc has been 15.5 for over a month,my dr has sent me to a hematologist. should i be concerned. only symptom i have is fatigue and no daily meds?

May have problem: For a WBC to stay at 15,000 level suggests there is a chronic infection or a hematologic problem. The WBC should be in the 10,000 range and that it has been elevated with fatigue requires work up for a subltle form of infection of the biliary system, GI tract or urinary system. With these probably having been investigated by GP then a hematologist is required to rule out a hematologic Ca.

Possibly not, but: An elevated white blood cell count can be due to many conditions, only some of which are serious. Typically elevated during an infection, but even strenuous exercise and pregnancy can elevate the WBC. I would have the test repeated to be sure it wasn't a lab error. Very occasionally an otherwise healthy person will continue to show an elevated WBC over many years with no development of illness.
