High T4

[Cat-222]

Hi I have just received some of my blood results from Medichecks

My TSH is 2.04 and my T4 is high at 23. I am just waiting to redo my T3.

My antibodies were normal - Thyroglobulin was 16 and Thyroid Peroxidase was 9

Please could you let me know are these levels OK many thanks

When did you take your last dose of Levo before the test? The recommended time gap is 24 hours, if you took your Levo before the test then you have a false high FT4. One wouldn't expect to see such a high FT4 with that TSH level.

Was this a private test?

What are the reference ranges for these results?

Did you take biotin or B Complex or any supplement containing biotin in the days before this test?

I am just waiting to redo my T3

Wasn't FT3 done from the same blood draw?

You can't do a stand alone FT3 test, it must be done at the same time and from the same blood draw as TSH and FT4.

Hi, thank you for your response. I took my thyroxine 24 hours before the test. On the morning of the test I didn’t take any. The test was private through Medichecks.The range was 12 - 22.

The reason the T3 failed was because they did not have enough blood to test it. I could only get enough to the first line on the tube and it should have gone up to the second line.

I don’t take any biotin or B supplements. I only take C , Zinc and Omega 3

I have palpitations, high anxiety and depression. Nausea in the morning. It’s a struggle to get through the day, I have no energy. That’s why I had my bloods checked

I have palpitations, high anxiety and depression.

Those can all symptoms of hypothyroidism.

I am suspicious of your high FT4 with that TSH level. If it were me I'd do another test with a different company. Monitor My Health is an NHS lab at Exeter hospital and you can get the basic thyroid test which includes TSH, FT4 and FT3 for £26.10 with code here:

If you struggle to do fingerprick tests I can post my tips for you, just ask if you'd like me to do that.

I was highly recommended to use Medichecks they are going to check my T3 and vitamin D when I get the kit through. I am going to a clinic to have blood taken because I don’t like doing the finger prick way. I tried to take blood from 3 different fingers, I did everything they recommended but it set my anxiety off and my fingers were bruised and stung after. Not doing that again. I will call them next week and ask them to recheck my T4 when they check my T3. I spent a lot of money so cannot afford to go elsewhere and cannot take the stress. Thank you for your advice, I appreciate it.

I didn’t have any vaccines.
