Fluctuation blood test

Hi

I got my blood test results back yesterday and although I am not taking any medication at the moment because I am still being monitored my TSH levels have gone down from 7.51 to 5.79 mlU/L

I have been taking vitamin supplements (Biocare TH Intensive) and I am wondering if that has helped with my blood levels returning to almost 'normal' levels.

Could it be the supplements or is it just that the blood levels fluctuate like this anyway?

thanks for the advise

Sonia

  • Where your blood tests at exactly the same time of day e.g. in the morning around 9am? Did you fast for a minimum of 12 hours overnight before every test? If you didn't then you would expect to see such levels of fluctuation and you should also make sure you do this before each test.

  • 1004Sonia,

    TSH levels fluctuate throughout the day and night. TSH is highest around midnight gradually subsiding throughout the early hours and morning which is why members are advised to book early morning blood tests and to fast (water only) as TSH drops after eating and drinking.

    Ask your GP to test thyroid peroxidase antibodies. Positive antibodies indicate autoimmune thyroid disease (Hashimoto's) and most GPs will treat hypothyroidism when TSH is >5.0 in the presence of antibodies.

  • 5.79 is hardly 'normal'. It is hypo, and your doctor is an idiot if he hasn't started treating you yet!

    Did s/he recommend you take the Biocare TH Intensive? If so, did s/he test your levels of iodine first? Because it has rather high levels of iodine which really aren't recommended for hypos - unless you are iodine deficient, and you wouldn't know that unless you are tested.

    As for whether or not it had an effect on your TSH... There's no real way of knowing. For a start, you would have to have your tests done at exactly the same time of day every time, as the others have explained.

    In any case, the TSH is largely irrelevant. It's not high TSH that makes you ill, it is low thyroid hormone, and apparently, they are not testing them. What all that iodine could be doing is stimulating your thyroid gland. But that is not a good thing. If you stimulate a sick gland, you just hasten its demise, it doesn't make it work better long term, it just burns out quicker.

    Besides, with a TSH of 5.79, you are still hypo, so it really doesn't matter. But, if I were you, I would give up the Biocare TH Intensive, and save your money for something that will really help you.

    Ask your doctor to test your antibodies, because if they are high, that can be another reason for TSH fluctuating.

    OMG!!! 490mcg iodine!! Definitely should have tested for iodine deficiency before supplementing with that!

  • Thanks for all the replies.

    Greygoose - I didn't realise that I could overstimulate the gland like that. Wow there is so much I don't know about this. I am going to be seeing the doctor on Friday to discuss my results and I will speak to her about having the other tests done.

    Appreciate the advise

    thanks

  • You are right - there is so much to learn. When in doubt run it past the 40,000 plus people here before embarking on any thyroid journey :-)

  • And, for goodness sake, stop the Biocare TH Intensive!!!

  • :-) OK will stop taking it. I ordered new batches this morning which I will return!

  • Good.
