> According the lab my endo uses normal on TSH is .27-4.2 and Free T4 is .93 to 1.7 His goal is to have my TSH at l-2. Sounds like Free T4 up. Honestly I don't understand the thyroid loop. But since my TSH went up to ll been very tired and changes in synthroid again need higher dose to lower the level. Could be you have a much better understanding of Thyroid so I did find many google searches that listed the meanings of if one number was low or high what it meant and used the Free T4 also. Love Phillipa ps not on lithium? As that can cause thyroid damage.
Thanks Phillipa. Most of my life I have lacked motivation and felt listless. More so since I started Lithium about 32 years ago. Maybe I just had a naturally underactive thyroid which was just made worse by the lithium. The lithium certainly isn't helping my thyroid levels. Trouble is here in the UK the NHS uses different laboratory techniques (I think) for measuring thyroid levels so the normal range differs. If anyone can answer my original question I would be very grateful.
