“The service from Selph was superb! I didn't know about hat to expect but everything was so well organized! The test kit arrived quickly and the test was easy to do. After I posted it back, it was tracked and Selph contacted me to let me know it was being processed. The results were e-mailed to me in just a couple of days and were very easy to understand. The whole process went extremely well and I would certainly use this company again. The price was competitive too.”

What you need to know about our Thyroid Blood Test

You can think of your thyroid gland as your body's thermostat. Thyroid problems can affect your mood, appetite, gut, weight or skin - amongst many other things.

An under-active thyroid slows everything down. You feel tired, cold, put on weight, have dry skin and struggle with constipation. An over-active thyroid makes you lose weight, feel hot and jittery and can give you diarrhoea.

Problems with the thyroid gland are common, particularly if you’re a woman, or if you have a history of autoimmune diseases such as type 1 diabetes or coeliac disease. Thyroid problems can develop at any age so it's important to check it every now and then, particularly if you have symptoms such as:

Weight loss or weight gain
Increased or decreased appetite
Diarrhoea or constipation
Tiredness and fatigue
Heavy or irregular periods
Changes in mood like irritability or depression
Dry skin and / or hair

Our Thyroid Blood Test checks the two main thyroid hormones, thyroid stimulating hormone (TSH) and thyroxine (T4), which are all we need to say if you have an under- or over-active thyroid gland.

What's tested in the Thyroid Blood Test?

Thyroid Health

Thyroid problems are common but we can test for them easily by measuring the levels of the two key thyroid hormones - thyroid stimulating hormone (TSH) and thyroxine (T4)
