triiodo- thyronine). Only the free (unbound) portion of triiodothyronine (free T3) is believed to be responsible for the biological action of T3. Measurements of free triiodothyronine (Free T3) concentrations, correlate more reliably with your clinical status than total triiodothyronine (T3) levels. Low levels indicate a poor conversion rate in the liver of FT4 to FT3. You can go for an ELISA to measure the level of these hormones

Could you please give me the catalogue number (or some form contact information) for kit for the total T3/T4. There are so many Immunotech companies but the one from France has a french website and I found it very tricky to navigate it. Same goes for the free T3 kit. Google just doesnt like the name of that company! Thank you so very much for this. Ishita
