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.

Thyroid-stimulating hormone (TSH) Tests of blood levels of thyroid-stimulating hormone (TSH or thyrotropin) may be used to check the overall activity of your thyroid gland. Levels of TSH, which is made by the pituitary gland, may be high if the thyroid is not making enough hormones. This information can be used to help choose which imaging tests (such as ultrasound or radioiodine scans) to use to look at a thyroid nodule. The TSH level is usually normal in thyroid cancer.
