Serum thyroid hormones

Serum thyroid hormones

Serum thyroid-stimulating hormone TSH levels can be measured accurately down to very low serum concentrations with an immunochemiluminometric assay . - Interpretation of deranged TSH levels depends on knowledge of the T and T values. In the euthyroid state, T , T and TSH 3 4 3 4 levels will all be within the normal range. Florid thyroid failure results in depressed T and T levels, with gross elevation of 3 4 TSH. Incipient or developing thyroid failure is characterised by low normal values of T and T and elevation of TSH. In 3 4 toxic states, the TSH level is suppressed ( Table 55.1 ). Serum thyroid hormones
