Hi Sue, results as follows
TSH 0.646 range 0.21-4.20
Free Thyroxine 23.200 range 12.00-22.00
Free T3 4.66 range 3.10-6.80
THYROGLOBULIN ANTIBODY 11.200 range 0.00-115.00
Thyroid Peroxidase Antibodies <9.0 range 0.00-14.00
Hope this makes sense to you as I haven't a clue. Thank you xx
Hi
That's the correct way to present a thyroid blood test result. Thank you.
Your TSH (a pituitary hormone) is nice and low, which means your thyroid isn't being thrashed to work harder.
Your Free T4 is just over the top of the reference range and your Free T3 is middling. You show no raised antibodies for auto immune thyroid disease, we all have a few antibodies washing around from time to time, these are no cause for concern.
Your thyroid doesn't look to be failing. But your conversion of T4 into T3 isn't as good as it should be, hence the slightly over range T4 and yet only middling T3.
When was the test taken? To be really sure there isn't a problem thyroid blood tests should be taken first thing in the morning when our demand for thyroid hormone is highest. I arrange my tests between 8 and 8.30 am. Don't eat beforehand either, just have a drink of water.
If I were you I would now look at what might be going on to slow your conversion down. Optimal conversion requires some optimal vitamins and minerals. Vitamin D should be over halfway in the range. Vitamin B12 needs to be closer to the top of the vast range rather than middle or below. Iron levels should be good, not just scraping into the reference range. Ferritin is especially important and needs to be half way through the reference range at least. You can't increase your ferritin much from iron tablets, you need to eat your way up that one. Liver, pate, blood sausage, etc have all been a great help to me in getting my ferritin levels up. And magnesium is also required for good conversion alongside selenium. People say "I eat 2 Brazil nuts every day for Selenium" but that's mostly no help now. Our land is depleted from this element and so we need a supplement for it.
You should never supplement iron without first having a full iron panel done by your doctor or private lab. Too much iron is worse than not enough!
So I would go and ask my GP (in your shoes) for a full iron panel, vitamin D, vitamin B12, and if he will do it Iodine tests and see what that throws up for you.
Your actual thyroid gland looks good, but your conversion is open to improvement. Not something a GP will ever pick up on sadly.
I hope that helps a bit.
