A thyroid TG value of less than 1tg/ml generally determines that there is no recurrence. Thyroid TG value is the result of thyroglobulin, which is produced from the thyroid gland, and this test can be done to know the condition of thyroid hormone in the body. Patients with thyroid cancer who have had surgery and then have this test done can find out if the thyroid cancer has recurred. If the thyroid TG value rises to 2tg/ml, there is a possibility of recurrence. People with thyroid disease should not have bad habits of drinking and smoking, do not stay up late, avoid anger and rage, and keep a happy mood. Thyroid TG value is not normal, need to cooperate with the doctor treatment, do not self-medication, to avoid adverse results.
