Son has leukopenia. No other symptoms. Loads of energy! Sweats at night, no fever. My mother and aunt thyroid issues. I Gilbert's syndrome. Ideas?

Mgt. I would recommend reviewing the smear findings with your PCP. They can also reorder the test, often the values normalize after an illness. If he has a family history of thyroid disease, autoimmune disease is a consideration. A workup of his endocrine system may also be indicated.
