Due to a national increase in coronavirus testing, our test lab partners are experiencing delays of up to 3-4 days when delivering results from other test kits. We ask for your patience and compassion during these unprecedented times, and we're deeply grateful for your continued understanding.

The thyroid is a gland located in the neck. It’s responsible for producing two hormones:

  • Thyroxine (T4)
  • Triiodothyronine (T3)

The cells in your body require these hormones to function normally because they regulate the speed at which cells work.

Testing your thyroid hormone levels can identify whether they may be too high or too low, which would indicate an overactive thyroid or an underactive thyroid.

How to place your order

Using a home test works in the following steps:

  1. Place an order and get your kit delivered to your door, or collect from a local post office (delivery is free)
  2. Collect a few drops of blood using a finger-prick test
  3. Send your samples to our UK-based, accredited partner laboratory (postage is free)
  4. Once your results are available (in 2 to 3 days), our doctors will review your results
  5. One of our doctors will contact you, via a secure and confidential message in your patient account, to let you know your results and give you advice and support on what to do next

In some cases, the doctor may need to ask for more information. They may contact you by phone, so make sure your telephone number is up to date in your online account.

How the test works

The thyroid test is simple and easy to use:

  • The test will contain 3 lancets (a device for pricking your finger) and a collection tube
  • Collect a drop of blood from your finger using a lancet
  • Place the drop of blood into the collection tube
  • Use the pre-paid envelope to post to our partner lab
  • Your sample will be used to test your cholesterol levels
  • Get the results 2 or 3 days after your sample arrives at the lab
  • A ZAVA Doctor will then send you advice based on your results
