Thyroid readings- update on yesterday's post

[cjbroon]

My readings from blood test on 14/10/21

T4 - 17.2 Range was 10 -22

TSH - 0.91 Range was 0.27 - 4.2

My readings from blood test on 09/07/21

T4 - 19.2 Range was 10 - 22

TSH - 0.18 Range was 0.27 - 4.2

Done via my GP and local Hospital. As they're within Range they're deemed as normal. Despite recent thyroid issues.

As per previous post ….next step is to get full thyroid and vitamin testing.

Yes, those results will be classed as normal because they are within range. However, if you still have thyroid issues it could be due to low T3 so it's important to test this. It's unlikely that you will get this done via your GP as even if he requests it the lab will override the request when TSH and FT4 are within range so you may have to do private testing, TSH, FT4 and FT3 should always be tested together.

I see from your other post that you take a multivitamin. This may contain biotin and if it does, and you didn't leave it off for 3-7 days before the test, your results may not be accurate if biotin was used in the testing procedure (which most labs do).

Multivitamins are not recommended here for many reasons, they contain too little of anything to help low levels or deficiencies, they tend to contain the cheapest, least absorbable and wrong form of active ingredients, plus they often contain things we should test for first and only take if we our levels are low or deficient, eg iron, calcium, iodine, Vit D. Best to test key nutrients - Vit D, B12, Folate, Ferritin - and supplement where necessary at the appropriate dose with the correct forms of the active ingredients.

Yes I've just noticed that the multivitamins do contain biotin. I didn't realise until it was mentioned that biotin could cause an issue.I'm going to have a look at the private tests available and I'll probably stop taking the vitamins meantime.
