Thyroid check

Our thyroid health check includes a blood test measuring T3, T4 and TSH levels thereby providing in-depth insight into your thyroid health.  The sample can be collected at home using our finger-prick blood test kit and offers an affordable alternative to private in-clinic thyroid tests. Results will be reviewed by our team of healthcare professionals and available on your personal online dashboard within days. 

It is thought that 1 in 20 people in the UK will experience a thyroid disorder in their lifetime, yet many people with such disorders don’t even know they have them. Typical symptoms of an underactive thyroid (hypothyroidism) or an overactive thyroid (hyperthyroidism) can include weight gain or loss, tiredness, muscle weakness and low moods.

However, these symptoms could be caused by any number of other things too, so the best way to identify any potential problem is with a thyroid function blood test.  Our home thyroid blood test kit will measure the three main markers recommended by the British Thyroid Foundation to identify problems:

  • Thyroxine (T4)
  • Thiiodothyronine (T3)
  • Thyroid Stimulating hormone

Thyroid function blood tests might not be accurate during illness, so avoid taking this test at these times.

What our customers say

Forth really helped me understand issues that I was having, which in the end turned out to be problems with iron absorption. Without their test I would never have known this. I now have the knowledge I need to improve.

Sean Conway

As a working mum, I often find myself training ‘tired’ as the demands of day-to-day life take their toll.  Forth has enabled me to gain a valuable insight into what is happening ‘under the surface’, so I  can adapt my training and lifestyle.

Kate Allan

As a former Olympic cyclist I always wanted to look after my health. This has never changed to this day but become a lot easier via Forth, it’s the only way to really understand your own body. 

Brian Smith

I enlisted the help of Forth to help me get to the bottom of my current health concerns. The test was really easy to and my results were available within day. Using Forth has helped me take the action needed to get my hormones back on track.

Holly Rush, 39

I suffer from a hereditary condition which causes my body to store too much iron.  My biggest issue before using Forth was getting an appointment with my GP.  Now using Forth I can track my iron quickly and easily and take action before levels start to affect my health

Mark Threfall, 29

Taking the test is simple just make sure you follow all the instructions so you follow the correct procedures. The customer service is second to none and the results are easy to understand and follow.

Matthew Bottrill

I'd put off getting regular blood tests before because of the long-winded process of a GP visit. Forth has changed all that. The process is very quick and very easy, with thorough, well-explained results delivered to your inbox within days.

Alice Hector

I was keen to use Forth’s service to help monitor my haematological markers in particular since I've had problems in the past and by the time they are picked up by the GP I'm normally feeling unwell.  The test was quick and easy to do and results were back very quickly. The results are also incredibly accurate, being almost identical to those from tests done by my GP the same day.

Alice Lethbridge

I ran my first marathon in 2014 which left me feeling exhausted and constantly unwell. What I didn’t know then was that my iron and vitamin D levels were incredibly low.  By using Forth to test key biomarkers has put me in control of the areas I need to improve.
