Before ordering private thyroid tests in the UK, read about getting a diagnosis and thyroid function tests to see which might be relevant for you. If you can’t get the tests done by your clinician, then consider ordering from our partner private testing companies.

Be aware that biotin can affect FT4 levels if you take more than 20mg a day. You should stop taking biotin at least two days before taking the test. Click here for more information

Thyroid UK staff are not qualified to interpret the test results for you. This may be done by your NHS doctor or a private doctor or practitioner. Thyroid UK has a list of Private Doctors & Practitioners who may be able to help you. You can also request a consultation from a BANT-registered nutritional therapist or join our online community to discuss your test results with other members.
