Ask my doc to test my 7 year old son for hashimotos. Told them family history and symptoms; always hungry, puffy face, peeling nails, very emotional, croaky voice. Was told results were marked normal, no further action, so asked for a copy. Only TSH done which was 3.42 (0.3-5.5). WBC 4.42 (4.5 -13.5) and RBC 4.06 (4.5-6.5) marked below range, ferritin 20 (7.0-150), should I be worried?
