Thanks for choosing health care magic for posting your query.
test is primarily meant to assess your thyroid
functioning. If the TSH is high it means you are hypothyroid and if it is low it means you are hyperthyroid. A few of the thyroid disorders are autoimmune but most of them are not. This test is very routinely prescribed if you have any of the symptoms of thyroid and in no way will tell you whether it is autoimmune or not.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
