Blood tests

When I went for last blood test I took my ndt and realised I shouldn't have. My result is:

T4 level 11.0 pmol/L last test was: 9.4

TSH 0.02 mu/L. Last test was: 0.23

Free T3 5.3 same as last time.

Does this mean I am over. Medicated?

Sandcastle, TSH 0.02 doesn't mean you are over medicated unless FT4 and/or FT3 are over range.

Thank you, I was getting worried

Sandcastle, I should have added that taking NDT a couple of hours before a blood test will often give a false high FT4 and FT3.

Yes it was silly of me. Also I am on Ldn so it's difficult at the moment balancing everything. Thank you for the help

Have you any symptoms of hyperthyroid? If not then NO you are not over medicated!! NEVER reduce your dosage based on blood tests alone!!

Not what you're looking for?
