Anyone can take this test, but some groups of people will benefit most from it. If you’re a woman, aged over 60, or have an autoimmune condition, this test would be particularly useful.

If you’d simply like an idea of your thyroid function without the hassle of a GP appointment, this is the test for you.

If you’re undergoing hormonal thyroid medical treatment, you cannot and should not take this test. Please seek medical advice if this is the case.

No, this test is designed for quick, at-home results, so you won’t need to send your sample to a lab.

All you need to provide is a small blood sample. This kit provides results in minutes, giving you an idea if your thyroid is underactive: no lab required!

As a professional-grade home test, you can expect highly accurate results.

If your result indicates high concentrations of Thyroid Stimulating Hormone (TSH), you should always consult a doctor for further guidance.

False results are possible in rare cases as this test relates to your immune system. That’s why you must always consult a medical professional if your result is positive.

Your body produces Thyroid Stimulating Hormone (TSH) to activate your thyroid gland. This allows your thyroid to deliver its functions for your body.

If you have high levels of TSH in your blood, this might indicate your thyroid is underactive and is unable to absorb all of your body’s TSH. This test measures the TSH in your blood.

If over 5μIU/mL of TSH is detected, the test will show a positive result. This means an abnormally high level of TSH is in your bloodstream.

You can take this test at any time of the day. There isn’t any known benefit from performing it at a particular time.

Thyroid Stimulating Hormone (TSH) is produced by the pituitary gland in your brain. This acts as the control centre for the thyroid gland, telling it when to produce certain hormones for vital bodily functions.

The pituitary gland produces more TSH when your thyroid isn’t producing enough hormones for the rest of your body.

High TSH is a key indicator of a potential thyroid issue, and measuring it is the first step towards getting better.

Having an overactive thyroid is called hypothyroidism. Typical symptoms include excessive fatigue, constipation, and unexplained weight gain.

There are also some particular telltale signs of an underactive thyroid. If you’re experiencing bodily hair loss, dry eyes, or a deepened voice, finding out your TSH levels might be a good idea.

If you’re not aware of having thyroid issues previously and have no symptoms, you can take this test as a one-off to check your TSH levels.

If you’ve had previous issues with your thyroid, your doctor can tell you how often to check your TSH levels. However, every 6 to 12 months would be a good timescale.

During pregnancy, it’s a good idea to check your TSH levels early on. Thyroid function is essential for foetal development, so you should take this test to ensure the best development for your unborn.

It’s possible to have an overactive thyroid: a condition called hyperthyroidism. This would be indicated by lower-than-normal levels of TSH rather than overproduction.

This test can’t tell you whether your thyroid is overactive. It’ll only tell you whether your TSH levels are too high, which indicates an underactive thyroid.

You’ll need to take a different test for hyperthyroidism. Consult your GP for further advice.

A positive result means the concentration of TSH in your blood is above 5μIU/mL, which is abnormally high. This isn’t a diagnosis of hypothyroidism, but it’s a sign that further investigation is required.

You should consult a doctor immediately after receiving a positive result. They’ll be able to conduct additional tests or figure out treatment, if appropriate.

A negative result indicates the TSH concentration in your blood is below 5μIU/mL. This suggests your TSH levels are within the normal range.

If you’re still feeling unwell, seek medical guidance as soon as possible. Although rare, it’s impossible to rule out hyperthyroidism based on these results. Consult your GP to find out the root cause of your symptoms.
