Thyroid Blood Tests

Thyroid Blood Tests

Blue Horizon Medicals offer a wide range of Thyroid Blood Test Profile Kits  - we are recommended by both The Thyroid UK Charity and the Thyroid Patient Advocacy service, which are both fantastic resources for those that are interested in their thyroid function. Thyroid UK have asked us to make it a little easier to select a test so we have created a table for you - they have been split into three levels - Basic Thyroid tests, Intermediate Thyroid Tests and Advanced Thyroid Tests. The number after the PLUS indicates the number of tests that are tested in that profile - so the Thyroid Check +6 has 6 inclusions, and the +15 has 15 inclusions.


Request your thyroid tests from Blue Horizon Medicals, the household name for home thyroid testing.



Basic Tests ( +1, +2, +3 ) - Basic Tests are usually available for free on the NHS - although NHS thyroid tests are usually limited to definitely TSH, usually FT4, and rarely FT3. Test frequency may also be restricted. If you are already on thyroid medication it may be useful to know your FT3 levels to monitor dosing.

Intermediate Tests ( +6, +10 ) -  These profiles look at thyroid antibodies, which may be present before the standard parameters start going out of range. Patients with raised thyroid antibodies will often have symptoms of thyroid disease. The PLUS TEN also looks other factors which may mimic thyroid disorders.

Advanced Tests ( +11, +12, +15 ) - These start to look further into thyroid issues and may not be needed by everyone. The +12 and the +15 include Reverse T3 meaning that only vacutainer collection is possible.

Thyroid Patient Stories


I just used one of your finger prick kits, to get some up to date blood testing of my Thyroid, B12, Vit D etc. I have a lack of free time, (with a business and 2 children) and it can be difficult to get an appointment at my GP's, and I would prefer not to spend any more time in a doctors surgery. I liked the convenience and speed of the finger prick test which was delivered quickly, took only a few minutes to do and I had the results back very quickly too. The "tips" sheet you  provided was very also very helpful.


Eleanor, Cheshire



The lab my GP surgery use would not test everything I needed to have an informed diagnosis, so in May this year I looked for alternatives through Thyroid UK and BH came highly recommended.

Once I'd pricked my finger the blood flowed brilliantly for about 2 seconds! No need to panic, following the instructions, I then massaged my finger to get the flow going again & was able to fill the capsule. Posted off, I was amazed to get my results 2 days later! Brilliant service & I have recommended it to so many others since, because it is so simple & quick.


Linda, Nottingham



I have done a fingerprick test before (Thyroid Plus 10) and eventually managed with some difficulty to get enough for the test. My results came back much as expected comparing to a previous GP test so I don't think I messed up completely!

I think all of us on the thyroid forum feel confident in what Blue Horizon offers so feel comfortable with the finger prick testing.

Susie, Gwynedd






I like to use your finger prick tests for my thyroid blood panel because I can choose the day and time, it is very easy to do and I get the results back quickly by email, so I can print them off. You offer a range of tests and the price is very competitive and you support the Thyroid UK charity. Keep up the good work.
