Blood sample collection options

You can choose your preferred collection method when you checkout

Finger prick kit (FREE)

You can do this test at home without the need for a doctor. We'll send you everything you need to collect your sample and post it back to us. And it's all included in the cost. We've put together a video that covers the process, making it easy to check and track your health from home.

Home nurse appointment (+£60)

We'll arrange for a medical professional to visit your home and collect your sample. This is great if you're unsure on how it all works or have trouble collecting a sample. No need to book a doctor's appointment or visit a clinic, we'll send you everything you need to collect a sample and post it back to our labs.

Visit a partner clinic (+£45)

Once you've ordered your test, look out for an email from our phlebotomy partners containing information and a link to book your appointment. We'll send you everything the clinic will need to complete the sample and post it back to our labs.

Organise a nurse myself (FREE)

If none of the above options work for you, you can arrange your own medical professional to collect your sample. There is no additional charge for this. Once you've ordered your test, we'll send you everything you and your chosen medical professional will need to collect a sample and post it back to our labs.

Still unsure how it works? You can find more information on collection methods and the service we provide in our 'How it Works' section.

What gets tested?

5 Biomarkers

Additional biomarkers can be added by personalising this test.

What are biomarkers?

Biomarkers are specific compounds we can detect in your blood sample that reflect different things about your health. Your test will tell you your levels for each of the above biomarkers, and whether they are in a normal range.

About flexible subscriptions

How does a subscription work?

When you purchase this test subscription plan, we will automatically send you another test kit in a few months. Don't worry - you have full control over when this will be, and you can change/cancel it anytime.

When you first purchase this test, you can choose your subscription options in the checkout. We do this, because we recommend taking multiple tests over time to track how your biomarkers change. You'll be charged per test kit (rather than monthly, for example).

Why subscribe to multiple tests?

One test will show you what areas you need to focus on, continued testing will help you learn how your training, diet and lifestyle is impacting your health.

How often should I test?

We recommend a follow up test 3 months after your first test, followed by a test every 6 months depending on your results, but its up to you!

Can I change what's tested in future tests?

Yes, you can tailor/customise subsequent tests (via your app) to focus on just the areas that need improving.

What this Advanced Thyroid Blood Test measures

5 Biomarkers

Thyroid Stimulating Hormone (TSH)

Thyroid-stimulating hormone (TSH) regulates thyroid function by stimulating the production of thyroid hormones T3 and T4, which control metabolism and energy production. Women are more likely to develop thyroid disorders than men. Abnormal thyroid levels impact weight, energy levels, mood, menstrual cycle and can cause erectile dysfunction in men.

Thyroxine (T4, free direct)

A thyroxine (T4) test is used to check that the thyroid is performing properly. An overactive thyroid can cause too much thyroxine to be released whilst an underactive thyroid can lead to too little. Abnormal levels can impact weight, energy, and mood. Free T4 measures the free or unbound levels of T4.

Triiodothyronine (T3, free)

Triiodothyronine (T3) is the active form of thyroxine (T4). High T3 levels may indicate hyperthyroidism, with symptoms such as fatigue, weight loss, irritability, and increased heart rate. Low T3 levels can suggest hypothyroidism, causing fatigue, weight gain, and muscle stiffness. Free T3 measures the free or unbound levels of T3.

Thyroglobulin Antibodies (TG)

The thyroglobulin antibodies (TG) test is useful in assessing thyroid function by detecting autoimmune activity. Elevated TG antibodies indicate that the thyroid is inflamed or under attack by the immune system. This test therefore aids in identifying and managing thyroid disorders, uncovering autoimmune causes, and guiding appropriate treatment.

Thyroid Peroxidase Antibodies (TPO)

Thyroid peroxidase (TPO) is an enzyme important in the production of thyroid hormones. Elevated TPO antibody levels suggests that the immune system is attacking the thyroid gland and can indicate autoimmune thyroid diseases like Hashimoto's thyroiditis and Graves' disease. Elevated TPO antibodies in individuals without overt thyroid disease can help predict future thyroid dysfunction.

Thyroid (T3 v T4)

GOOD
Dr Thom Phillips

Although TSH is suppressed, T4 is in range. This suggests subclinical hyperthyroidism, which could indicate an intermediate situation either tending towards developing an overactive thyroid or the process of altering dose of medication to regulate a thyroid condition.

Advanced Thyroid Blood Test, recommended by our doctors

"An advanced thyroid test includes two thyroid specific antibodies - thyroglobulin and thyroid peroxidase. Thyroglobulin antibodies are linked to autoimmune thyroid diseases like Hashimoto's and Graves' disease, while thyroid peroxidase antibodies indicate inflammation. High levels of these antibodies suggest thyroid problems, helping in the diagnosis and management of thyroid disorders."

Frequently asked questions

This is what our customers ask us about the most. For more information, try our help centre.

What is the thyroid?

The thyroid is a small, butterfly-shaped gland located in your neck. It produces hormones that help regulate metabolism, energy levels, and overall bodily functions.

What does the thyroid do?

The thyroid produces hormones like thyroxine (T4) and triiodothyronine (T3), which help control metabolism, heart rate, body temperature, and energy levels.

What are early warning signs of thyroid problems?

Early signs of thyroid dysfunction can include:

  • Underactive thyroid (hypothyroidism): Fatigue, weight gain, dry skin, hair thinning, feeling cold, depression.
  • Overactive thyroid (hyperthyroidism): Unexplained weight loss, rapid heartbeat, anxiety, sweating, difficulty sleeping.

Can this test detect an overactive thyroid?

Yes, this test measures thyroid hormones (T3, T4) and thyroid-stimulating hormone (TSH) to assess whether your thyroid is overactive (hyperthyroidism).

Hyperthyroidism can be caused by conditions such as Graves’ disease, thyroid nodules, excessive iodine intake, or thyroid inflammation.

Can this test detect an underactive thyroid?

Yes, the test checks for low thyroid hormone levels and high TSH levels, which can indicate an underactive thyroid (hypothyroidism).

Hypothyroidism is often caused by Hashimoto’s thyroiditis, iodine deficiency, or certain medications. It can also develop after thyroid surgery or radiation treatment.

Can this test detect thyroid cancer?

No, this test does not screen for thyroid cancer. However, our TruCheck cancer test can help detect cancer markers in the blood.

Can I use this test while taking thyroid medication?

Yes, but your medication can affect your results. If you are on thyroid treatment, please include information about your medication in your Forth profile and consult with your doctor before testing to ensure accurate interpretation of your results.
