Has anyone sent thyroxine tablets for lab analysis to determine the potency?
I have been healthy on liquid thyroxine for a few years, after being ill for 20 years on tablets. New GP surgery wants me to change back to tablets in order to save money. I will be allowed a little liquid to top up from 100mcg to my 120mcg. I want to get each batch of tablets lab tested, so I know the real potency, and can top up to an accurate dose. Accuracy is everything for me.
