TRH Stimulation Test

The TRH Stimulation Test measures how well the thyroid gland responds to thyrotropin-releasing hormone (TRH), which is produced by the hypothalamus in the brain. During the test, a healthcare provider injects TRH, and blood samples are taken afterward to check levels of thyroid-stimulating hormone (TSH) from the pituitary gland. The test helps evaluate thyroid function and diagnose conditions like hypothyroidism or assess pituitary gland activity. It's a useful tool in understanding how your body regulates thyroid hormones, which are vital for metabolism and overall health.
