What Results of Thyroid Stimulating Hormone mean?

Interpretations

  • If your TSH level is increased, it usually indicates that you have hypothyroidism. Hashimoto’s thyroiditis is the most common cause of primary hypothyroidism. 
  • If your TSH level is decreased, it usually indicates hyperthyroidism. Grave’s disease, multi nodular goitre, toxic nodule are some of the common causes of hyperthyroidism. 
  • Whether high or low, an abnormal TSH indicates an excess or deficiency in the amount of thyroid hormone available to your body, but it does not indicate the reason why. So, additional tests like free T3 and T4 should be done to confirm the cause.
