Cooking time. There is substantial variation, with cooking time being the primary variable affecting doneness (soft-boiled vs. hard-boiled). It usually varies from 15â17 minutes for large hard-boiled eggs, 1â4 minutes for large soft-cooked eggs and 12 minutes for the best results.
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.

TSH (thyroid stimulating hormone) is part of a feedback loop controlling levels of thyroid hormone. TSH levels are high when parts of this feedback loop do not function properly. The commonest cause is a problem in the thyroid resulting in hypothyroidism, treated with thyroid hormone.A tumor in the pituitary gland or the hypothalamus can also cause high TSH levels and hyperthyroidism. thyroid scan and thyroid tests identify the cause. Thyroid stimulating hormone (TSH) is a protein hormone released from the pituitary gland in the brain that stimulates the thyroid to produce thyroid hormone, which regulates body metabolism.
