EFFECTS OF PERCHLORATE IN DRINKING WATER

In Vivo Effects. In general, the serum TSH level is affected less by medications than thyroid hormone concentrations (Table 1). For example, Estrogen-induced TBG elevations raise serum TT4 levels but do not affect the serum TSH concentration, because pituitary TSH secretion is controlled by the FT4 independent of binding-protein effects. ................
