It makes no sense: If your T4 and t3 (liothyronine) levels are normal, there is no way the TSH would be that high.

Funny thyroid result: Confusing. First correlate any tests with a clinical pattern. Discuss with your doctor. Tsh suggests you may need more thyroid or have a problem converting thyroid . You might try Armour Thyroid if your doctor agrees and adjust the dose till the TSH is 3 or less. First rule out a lab error.

Initial diagnosis?: If the t3 (liothyronine) and T4 levels have been consistently normal, and the TSH has been consistently high, you may have thyroid hormone resistance. This is an inherited disorder, so other family members will have a similar problem. It is typically initially misdiagnosed as hyperthyroidism, and then treated with surgery or radioactive iodine. You would require large doses of thyroid hormone to correct tsh.
