Thyroid disorders: It sounds like your thyroid is functioning well right now, but the high antibody level indicates possible future autoimmune thyroiditis in the future. I'm not sure why you had this full work up. If you are symptomatic of thyroid disease, you might want to see an endocrinologist even with your normal results. If you do not have symptoms, your doctor may want to monitor your TSH periodically.
