i had my appointment with endrocolgist today and he said my thyroid is normal he couldn't explain why I had high ft4 and lowest tsh in Sept. I asked could the propranolol lowered the results he didn't think so. He wants me to do 24 hrs urine test wasn't sure if propranolol will effect it said ok to just stop it for the test? ?the thing I noticed the hospital blood test and medicheck which was done same time same nurse one needle going in are different results anyone else have that I enclose the copies
appointment update: i had my appointment with... - Thyroid UK
appointment update
propranolol will affect TSH, Ft4 and Ft3
Extraordinary how endocrinologist is unaware
Over 20 years that I was on propranolol I saw 6 leading thyroid specialist doctors or endocrinologists …….not one of them considered propranolol was a problem
24 hour urine test ….likely for checking cortisol levels
did you have a thyroid problem before you went on propranolol I was put on them by endrocolgist in a hospital in London. Can you check my other level is normal I will enclose thanks

I have removed your image for two reasons
1) It's impossible to read the figures, you need to zoom in on the actual figures and leave out all the white space
2) Your full name and NHS number were showing, this leaves you vulnerable to identity theft.
Feel free to repost your image so that it is readable and doesn't show your personal details.
Do you have a printed copy of the London results?
There may be an error, it may relate to something else.
Apart from 1 elevated FT4 there’s no confirmed sign of thyroid issue, some your FT4 have been on low side.
Your repeat function have all in range.
A Private TRab TPO & TGab antibodies all negative a NHS TSIab also negative.
Propranolol does have an affect on lowering conversion from FT4 to FT3. Which is why it often prescribed along side an anti thyroid. It doesn’t have a sufficient impact on it own to reduce continuously high levels - that need a specific treatment.
This tends to apply to those who are on higher doses for a long time.
You had 10mg x2 daily for only a few short weeks. I don’t think that would have a significant impact.
this is one of London result
definitely no error. Unfortunately doctors don’t look for causes or one off elevations. They only look to treat when there is a continuous issue.
Would often be helpful if they did, but they will be looking as other explanations such as cortisol.
