Brief Answer:
Antibodies will persist for some time.

Detailed Answer:
Dear ma'm , hi! you had Hashimoto's thyroiditis for which you underwent total thyroidectomy. now you will require thyroxine replacement for life. dose may vary. presently you are taking 150 mcg and with that your TSH is 16 so that suggests you need to increase the dose. once the thyroid balance is achieved you will feel better. antibodies will take time to get suppressed. regards!
