I took advice from the forum late last year and ordered medicheck tests which I posted in December. After reading lots of very helpful advice and links in response, I went to see my GP to ask if he thought I may have a conversion problem. He was not convinced but ordered a repeat Thyroid test, this time to include T3 (hurrah!). I will now post some historic test results to give you context for my question:
date TSH T4 T3
2012 0.1 18.1 not tested
2013 0.08 18 "
2016 0.1 18.3 "
08/17 0.08 18.5 "
12/17 0.159 22.1 4.36 private test
01/18 0.13 13.7 4.7
The private test found TPO antibodies too, but that was not retested.
Even if I ignore the private test, that seems quite a drop between August and January, and looks out of place on the trend, doesn't it? What could cause this? And should I still pursue the conversion question?
I can think of a couple of changes since August: my ferritin level increased from 33 to 63, plus on advice from the forum I started taking vit D daily (although my GP thought this unnecessary as many people 'do well enough on that level' (35))
I have not gone back to him to follow up this latest result as I need to be well-prepared!!
Many thanks in anticipation.
