How to get your thyroid function test kit online

The process is quick and easy. Just follow these simple steps:

  • Fill out a short online questionnaire
  • Select your preferred test kit option
  • Once approved, your test kit can then can be posted to your preferred address or you can collect it from a local post office instead

How to use the thyroid function test kit

  • Before you take your sample, you should wash your hands with warm soapy water (it is difficult to collect blood if your hands are cold)
  • Dry your hands and use the included alcotip swab to clean the fingertip you would like to use
  • You should use the third or fourth finger of your non-dominant hand
  • Twist and remove the purple stick from one lancet, put it on your fingertip and press the purple button at the end - don’t worry if it doesn’t work straight away, you can use one of the remaining two lances to try again
  • You should notice a small drop of blood forming on your fingertip, as your skin has been punctured
  • Use a clean tissue to wipe the first drop away, hold your hand downwards and massage the side of your finger to form another drop of blood
  • Use your other hand to gently squeeze the finger you are using and catch the drops in the collection tube
  • You should fill the small tube to the upper line. If you are unable to fill it, please use an additional lancet on another finger to complete the sample
  • Once your sample is complete, you can use the supplied plaster to stop the bleeding, put the screw lid on the collection tube, turning it upside down and back a few times times, until it is closed securely
  • Please make sure you put your details on the sticky label and affix it on the tube – the lab will not be able to analyse your sample otherwise
  • You then need to put your sample tube inside the protective wallet and put the wallet into the prepaid envelope, along with your used lancets
  • You can use any UK post box to send your test kit back to the partner lab

How do the results work?

  • Your results will be provided to you via your account
  • They should be ready within 2-3 days of the laboratory receiving your sample
  • When your blood sample reaches the laboratory, it will be used to measure 2 hormones (TSH and T4) that show if your thyroid is working properly
  • It will report whether these levels are within the normal range or outside of it (too high or too low)
