Helvella, thank you! I had forgotten about the Chingkerrs calculator, (despite having it bookmarked 😆). Would it seem too ungrateful to ask if it can be modified to include fT3 ÷ fT4 calculation so that it can be used in conjuction with Midgley et al's research: 'variation in the biochemical response to l-thyroxine therapy and relationship with peripheral thyroid hormone conversion efficiency '?
Thank you too to FancyPants54 and hubbie: I frequently use and recommend your calculator.
Oops, sorry to digress! No I haven't read the previous discussion with Decant et al I got an email notification that you had posted and came straight to this post. I could easily spend all day on Healthunlocked, unfortunately the demands of life get in the way!
