3. What are the additional blood tests that may be performed?
Thyroid panel (T3, T4 and TSH) - to help diagnose and differentiate various thyroid disorders.
Thyroid auto - antibodies which help in differentiating different types of thyroiditis and identifying autoimmune thyroid conditions.

Both an underactive and overactive thyroid gland can cause symptoms. An enlarged thyroid gland either dissure or nodule, hoarseness of voice and symptoms like fatigue, depression, anxiety, weight loss or weight gain, temperature intolerances, hair loss, dryness of skin, or menstrual irregularities indicate a thyroid disorder.
