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.

Frequently asked questions

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

What is the thyroid?

The thyroid is a gland in your neck that produces the hormones thyroxine (T4) and triiodothyronine (T3). These hormones regulate the activity of the cells and tissues in the body.

T3 is the biologically active hormone, with your body converting T4 into T3. This hormone controls the metabolism, the speed at which cells work. The more T3 is produced or converted, the faster cells metabolise. The level of hormones produced by the thyroid gland are controlled by the pituitary gland, which releases thyroid stimulating hormone (TSH) to stimulate the thyroid.

What are the early warning signs of thyroid problems?

The early warning signs of thyroid problems can include:

  • being sensitive to the cold or heat
  • weight gain / weight loss
  • constipation
  • low mood
  • muscle aches and weakness
  • loss of libido
  • mood swings
  • issues sleeping

Check out further information on symptoms in our answers below.

What causes an overactive thyroid?

The most common cause of an overactive thyroid (hyperthyroidism) is a condition called Graves’ Disease. This is an autoimmune condition where your body releases antibodies that cause your thyroid to produce too much thyroid hormone.

Less common causes are thyroid nodules and medicines that increase the amount of iodine in your body.

What causes an underactive thyroid?

An underactive thyroid (hypothyroidism) is usually caused by your immune system attacking the thyroid gland and causing it damage. This reduces its ability to produce sufficient hormones.

What are the symptoms of an overactive thyroid?

The symptoms of an overactive thyroid include:

  • Nervousness
  • Changes in mood
  • Hyperactivity
  • Anxiety
  • Fatigue
  • Weakness
  • Sleep disturbance
  • Heat sensitivity
  • Irregular heartbeat
  • Swelling in your neck

What are the symptoms of an underactive thyroid?

The symptoms of an underactive thyroid include:

  • Fatigue
  • Feeling cold
  • Depression
  • Weight gain
  • Muscle cramps and aches
  • Low sex drive
  • Brittle hair and nails
  • Dry skin
  • Irregular or heavy periods

Can I have someone take my blood for me?

Yes. We offer two options if you do not want to do our finger prick test. The first is a home appointment where a nurse comes to your home to take a blood sample. The second is to visit a Phlebotomy clinic near you that offers a blood sample service.

A blood sample will be taken from your vein and we will provide you with everything you need to give to the nurse to allow them to take the sample.

The nurse will give you the blood sample to return to us using the pre-paid envelope provided.

Does a doctor review my results?

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."
