A thyroid panel with TSH is a blood test that measures the levels of thyroid hormone in your bloodstream, including TSH. Thyroid stimulating hormone (TSH) is produced by the pituitary gland and helps to regulate the production of thyroid hormones (T3 and T4) by the thyroid gland.
This test is typically ordered if your doctor suspects that you may have a thyroid disorder, such as hypothyroidism or hyperthyroidism. Abnormal levels of TSH can indicate an imbalance in thyroid hormone production and can help your doctor diagnose and monitor thyroid conditions.
In addition to TSH, the thyroid panel also includes tests for T3 and T4 levels, which are the main thyroid hormones that regulate metabolism, energy levels, and other bodily functions. By analyzing the levels of these hormones in your blood, your doctor can determine if your thyroid gland is functioning properly or if further evaluation and treatment are necessary.
