Recent blood tests

Recent blood tests

Hi, just looking for a bit of advise pre my consultant appointment. I'm currently taking NDT; 2 grains in the morning and 1/2 at about lunchtime. This is against advise to take 1.75 grains, first thing. Reason being that I was still unwell and my last blood test were low on both T4 and T3 and I had quite a gap between appointments. Currently I feel ok most of the time but think I definitely swing between hypo and hyper. And the hyper swings worry me a little. The other thing with my recent results is that instead of going for the tests first thing I went at 12:40pm and had taken my usual dose in the morning. I didn't really want to do this but I couldn't get an appointment in the morning for a couple of weeks and needed something to show my consultant.

I realise it's all a bit of a mess, but just not quite sure what to think/do now. Probably should of delayed the blood test and consultant appointment.

Any thoughts would be really appreciated

  • CBann,

    T3 peaks in the bloodstream for up to six hours after taking a dose so your FT3 result has probably been skewed by the NDT you took in the morning and is showing falsely high. It is recommended that thyroid meds should be taken after a blood draw to avoid this.

    Thyroid peroxidase antibodies are mildly positive for autoimmune thyroid disease (Hashimoto's) and it may be this which is making you feel as though you are swinging between hypo and hyper. Low iron or ferritin can also make you feel hyper with hypo blood results. tiredthyroid.com/feeling-hy...

    There is no cure for Hashimoto's which causes 90% of hypothyroidism. Treatment is for the low thyroid levels it causes. Many people have found that 100% gluten-free diet is helpful in reducing Hashi flares, symptoms and eventually antibodies.

    Ferritin is high in range. If you are supplementing iron you should stop.

    B12 and folate are good.

  • Thanks Clutter. I am not quite sure what to do now really. Do I go to the consultant with these results or do the bloods again and delay my appointment. I probably did take my meds around 6.30 however as that's the time I get up. I am not supplement iron specificallly but there could be some in the multivitamin that I take. I am gluten free most of the time but i am not overly careful with it. Maybe I need to give it a bit more attention. Thanks again

  • CBann,

    If it was 6 or more hours between your NDT dose and blood draw you are mildly over medicated. I would reduce dose by 1/4 grain. Tell your endo you increased dose before your blood test and have reduced it after seeing FT3 is over range.

    If you have gluten sensitivity or intolerance the teensiest amounts of gluten will be harmful. If you want to see whether gluten-free can be helpful you need to be 100% gluten-free for a few weeks.

  • Thanks Clutter, to be honest I am not convinced the blood tests aren't skewed so I might just do them again and reschedule to be sure. Could that skew the anti body result as well?

    I'll give the gluten free thing ago too.

    Thanks
