It makes thyroid-stimulating hormone, or TSH, which tells the thyroid gland how much T4 and T3 to produce. The TSH level in your blood reveals how much T4 your pituitary gland is asking your thyroid gland to make. If your TSH levels are abnormally high, it could mean you have an underactive thyroid, or hypothyroidism.âTSH levels go in the opposite direction of your thyroid hormone,â Dr. Doria-Medina explains.he TSH level in your blood reveals how much T4 your pituitary gland is asking your thyroid gland to make.

Thyroid stimulating hormone (TSH) levels evaluate the functioning of the thyroid gland. TSH instructs the thyroid to produce thyroid hormone. High TSH levels indicate that the thyroid is underactive, and a low TSH means the thyroid is overactive. Abnormal TSH levels alert medical professionals to diseases of the thyroid gland.
