| The profile for free thyroxine is that obtained using equilibrium dialysis and low sample dilution. |
| For example, thyroxine for thyroid cancer, tamoxifen for oestrogen receptor positive breast cancer, and stilboestrol for cancer of the prostate. |
| Therefore, serum thyroxine and triiodothyronine concentrations do not change, nor do serum thyrotropin concentrations. |
| The thyroid releases too much of the hormone thyroxine, which increases the person's basal metabolic rate. |
| When thyroxine secretion is reduced, all metabolic processes proceed at a reduced rate and basal metabolism falls. |
| Breast feeding should not be stopped in mothers treated with thyroxine for hypothyroidism even if the infant is hyperthyroid. |
