Yes, ultrasound, needle biopsy and follow up ultrasound a year later + labs that showed normal thyroid function. They will ultrasound again in a few years unless changes. I think thyroid function tests will be ongoing. I told my primary I'd rather not have another specialist involved unless it was necessary, so I nixed an endocrinologist for now. These people are so silo'd into their specialties that it becomes a full time job trying to coordinate communication. Already got a primary, hematologist, cardiologist, and dermatologist.
