Normal thyroid levels

Can anyone help with these results.

My husband had thyroid bloods tested , he is unmedicated but because he falls asleep a lot I suggested he got the test. Blue horizon was used.

TSH. 1.84. (0.27-4-20)

T4 total. 78.5. (64.5-142.0

FT4. 14.28. (12-22)

FT3. 4.76. (3.1-6.8)

Wondered if anyone would post thoughts on the T4 and T3. They seem quite low to me. But I know very little 😐

  • Hi Gcart. I wondered why you thought it was a thyroid problem ( I'm not saying it's not).

    A lot of folk only feel well when the tsh is below 1. The FT3 should be 25% of the T4, so that looks fine from that point of view. Has the GP done any tests - just to compare, as results can change over a few weeks.

    By "falls asleep a lot" do you mean suddenly without warning? That could be narcolepsy.

  • GCart,

    The results are euthyroid (normal). FT4 and FT3 are normal for someone not on replacement. There's no sign of thyroid dysfunction.

  • Has your husband had his iron (both haemoglobin and ferritin), vitamin B12 and vitamin D levels tested? If not those should be tested. Lots of people with normal thyroid function have issues with their vitamin and mineral levels and those are the most common ones that are deficient.

  • Are there pauses of 10 or more seconds in his breathing when he's asleep? This would suggest sleep apnoea.

  • Thank you all for getting back, will take advice about minerals and vitamins and get them tested privately. I was just clutching at straws ! Just thought it might rule it in or out.

  • An important article about sleep apnoea and trips to the bathroom...

  • I have been diagnosed with Idopathic Hypersomnia because I fall asleep a lot, have difficultly waking in the morning, am often drowsy (excessive daytime sleepiness), and sometimes experience sleep paralysis: it's like narcolepsy but without cataplexy. These are considered CNS disorders. The neurologist thinks it is a different problem to my auto-immune hypo-thyroidism; sleep apnoea was ruled out and they couldn't find single reason for my symptoms, hence the idiopathic. Not wishing to over-alarm you but I know others who have been diagnosed with hypersomnia/apnoea when serious medical causes have been overlooked (e.g. hidden tumours). So, I think it is certainly something that is worth having checked out - perhaps ask GP for a referral to the nearest sleep clinic (I'm in Newcastle upon Tyne and saw Dr Kirstie Anderson). However, there's no cure and the treatment is Modafinil which I hate although it can keep me going at work when symptoms get awful. Happy to discuss further by PM if you want.

  • Hi Sandy, can I hear more about this please?

  • Many thanks! How can someone measure their basal temperature?

  • This is fantastic! Thank you!
