Dear all, just got the results of my blue horizon blood test. I have been looking into whether my extreme problems with food intolerances are due to thyroid problems in the hope that I can feel better (I feel rough and very tired and achy a lot of the time) and expand my diet a little if I take thyroxine. They are: Biochemistry
CRP 0.40 <3.0 mg/L
Ferritin 65.7 20 - 150 ug/L
Free T4 13.58 12 - 22 pmol/L
Free T3 4.85 3.1 - 6.8 pmol/L
TSH H 7.89 0.27 - 4.20 IU/L
T4 Total 87.0 64.5 - 142.0 nmol/L
Anti-Thyroidperoxidase abs 9.4 <34 kIU/L
Anti-Thyroglobulin Abs 15.3 <115 kU/L
Vitamin B12 L 146 Deficient <140 pmol/L Insufficient 140 - 250 Consider reducing dose >725
Serum Folate 31.06 10.4 - 42.4 nmol/L
This TSH value is rather high and is worse than it was in July from my GP (5.91) and August (4.34) which I think will be useful to talk to them about. I was careful this time to take a fasting test and also had been back on the gluten for 10 days before taking the test and the anti bodies were higher than for the gluten free test which I did for the GP in August (only Anti-Thyroid peroxidase tested then) but not significant. I will look into finding a B12 supplement which I can take and also it is off the gluten now (sigh, the diet is really really hard!).
I hope it will be worth the £89 and great difficulty getting the blood out on the finger prick method (it took over and hour and I had to keep re-pricking my fingers to get anything like enough, very hot water was the most helpful thing to get the blood flowing!).
Lets hope that the GP will take some note and I can give the hormones a go! She contacted an endocrinologist who said that they would only consider treating if TSH showed a clear progression towards 10 with symptoms or went over 10 by which time I expect to feel really really bad!
Has anyone any references or information that I can take with me when I next go and see them in order to make a case for treatment with high TSH but all other things in range except B12. My particular really bad food issue is with salicylates (and amines and dairy and gluten and eggs and fermented things etc.!) which are known to increase the tissue resistance to thyroid hormones so that someone needs a higher level of hormone to feel OK.
