1. The effect of the beta-1-adrenoceptor blocking agent, Atenolol, on serum levels of thyroxine (T4), triiodothyronine (T3) and reverse triiodothyronine (rT3) was studied in twelve hyperthyroid patients

2. Take, for instance, the thyroid and the two hormones it produces, triiodothyronine and thyroxine.

3. Central nervous system ischemia is prevented or minimised in a patient who has suffered an acute insult by administering a protective amount of a thyroid hormone such as levothyroxine, liothyronine, L-3,3',5'-triiodothyronine or L-3,5-diiodothyronine, preferably in the form of their sodium salts.

4. Most of these Analytes are measured by immunoassays using monoclonal or polyclonal antibodies.: All the technologies used in multiplexing are based on the principle of screening of multiple Analytes in single cycle of the assay.: This seventh edition covers new Analytes and adds information on reference intervals for steroids, free thyroxine, and free triiodothyronine.
