TSH (thyroid stimulating hormone)

Our Price: $45.00



A thyroid-stimulating hormone (TSH) blood test is used to check for thyroid gland problems. TSH is produced when the hypothalamus releases a substance called  thyrotropin-releasing hormone (TRH). TRH then triggers the pituitary gland to release TSH.


The TSH test is often the test of choice for evaluating thyroid function and/or symptoms of hyperthyroidism or hypothyroidism. It is frequently ordered along with or preceding a T4 test. Other thyroid tests that may be ordered include a T3 test and thyroid antibodies (if autoimmune-related thyroid disease is suspected).


TSH testing is used to:


  • Diagnose a thyroid disorder in a person with symptoms

  • Screen newborns for an underactive thyroid

  • Monitor thyroid replacement therapy in people with hypothyroidism

  • Diagnose and monitor female infertility problems

  • Help evaluate the function of the pituitary gland (occasionally)

  • Screen adults for thyroid disorders, although expert opinions vary on who can benefit from screening and at what age to begin
