Calculate thyroid's secretory capacity (SPINA-GT) from equilibrium TSH and total T4 concentrations.

TSH |
Thyrotropin (TSH) concentration in mIU/l |
T4 |
Total thyroxine (TT4) concentration in nmol/L |
This function is able to do vectorised calculations.
This function returns thyroid's secretory capacity as a numeric result representing a single value or a vector, depending on the vector length of the arguments. Results are in pmol/s.
The software functions described in this document are intended for research use only. Hormone levels should have been obtained simultaneously in order to avoid bias by transition effects.
