TSH Test

Our TSH (thyroid stimulating hormone) finger prick blood test is the entry level test to check whether your thyroid is functioning as it should be.

TSH helps to regulate the production of hormones in the thyroid glands. In turn, these hormones help to control a number of functions including your metabolism and the speed at which your body converts food to energy.

It is estimated than 1 in 20 people in the UK are affected by a thyroid disorder. Women are more likely to be affected than men.

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

It was trying to better understand my health (and improve it) what intrigued me to take a Forth blood test. Ordering the test was easy and I received a notification email that my results were ready just 1 day after the blood sample was taken.  The dashboard is pretty cool and an easy way to track how many biomarkers are in normal range, which ones need attention and finally which food types can help to optimise these biomarkers.
