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.

At the same time, the blood test showed I had normal levels of the thyroid hormones T3 and T4, which play a critical role in regulating metabolism. The doctor said my levels of TSH, the thyroid stimulating hormone that tells the thyroid to make T3 and T4, were too high, however. A high TSH is the marker that most endocrinologists use to diagnose hypothyroidism. It means the pituitary gland is telling the thyroid, âGo, go! Work harder!â And the thyroid is saying, âChilll man, Iâm sooo sleepy.â Conversely, too little TSH means hyperthyroidism, or an over-active thyroid.
