TSH Test

Our TSH blood test kits allows you to check your levels of thyroid stimulating hormone with a simple finger prick. Your TSH levels are a key indicator as to whether your thyroid is functioning as it should be - something that can play a vital role in your overall wellbeing.

1 in 20 adults in the UK is thought to have a thyroid disorder, with women likelier to be affected than men.

With our finger prick blood test kit, you provide a sample and send it back. Within a matter of days, we’ll have your sample analysed in an accredited UK laboratory and the results made available to you on a digital dashboard.

Why take a TSH test?

A TSH test is ideal for those who suspect they may have a thyroid disorder. Symptoms of this could include:

  • Weight loss or weight gain
  • Feeling low or anxious
  • Suffering fatigue or muscle weakness

Benefits of TSH testing

TSH levels that are either too high or too low can cause a range of symptoms that are particularly unpleasant to live with. These include weight gain or weight loss, a low mood, feelings of anxiety and extreme fatigue.

By taking a TSH test at home, you will get fast and accurate insight into your thyroid function which can help you to:

  • Seek out treatment through your GP
  • Track whether any existing treatment you are receiving for a thyroid disorder is effective
  • Rule out a thyroid disorder as the cause of any of the above symptoms if your levels are normal

What our customers say

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

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

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

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.

Jude Peck, 42

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'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

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 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.
