Monitoring & Testing

Following hypothyroid diagnosis 15 months ago, I am now on 75mg levothyroxine. Muscle pain has receded but troubled regularly by insomnia and also my voice has changed so it’s hoarse and weak much of the time (which I read could be a symptom?). I asked to be retested but my gp is resisting as he says my last result 4/9/17) was ‘perfect’. I’ve now gained a print-out of the last test result which just says: Serum TSH level 1.12mu/l which the lab says ‘suggests adequate replacement with thyroxine’. I’d like to have further tests done - can you guide me as to where to get these done, and what I should ask to be tested?

Thank you

Many thanks


You're welcome. :)


Just testing a TSH tells very little. You need to know FT4 and FT3.

For full evaluation you need TSH, FT4, FT3, TT4, TPO and TG antibodies, plus vitamin D, folate, ferritin and B12 tested

You are unlikely to get full thyroid and vitamin testing from GP

Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have money off offers.

All thyroid tests should be done as early as possible in morning and fasting and don't take Levo in the 24 hours prior to test, delay and take straight after. This gives highest TSH and most consistent results


Thank you
