Because Tg is thyroid-specific, serum Tg concentrations should be undetectable, or very low, after the thyroid gland is removed during treatment for thyroid cancer. Years of publication ranged from 1983 to 2011. Using this logic some newer studies have suggested that a more "normal" TSH reference range is somewhere between 1.0 and 2.5 uIU/ml and anything higher than 2.5 is considered "high" (7). With this logic you can have a "high" TSH anywhere between 2.5 and 5.5, even though it technically falls within the "normal" range: WebA good thyroid doctor will treat a hypo patient clinically by testing and adjusting Free T3 and Free T4 as necessary to relieve symptoms, without being constrained by resultant TSH levels. This site needs JavaScript to work properly. If the authors did include preoperatively hypothyroid patients and did not provide data to calculate an incidence, the proportion of patients being hypothyroid postoperatively was defined as a prevalence.
