How to order a vitamin D test online in the UK

You can request a vitamin D test through ZAVA’s online doctor service. Follow these steps:

  • Complete a short online questionnaire about your health and lifestyle in a few minutes
  • Select your vitamin D test kit and complete your request
  • Your test kit will be sent to your preferred address by post, or you can choose to collect it from a Post Office

How to use the test kit

Your vitamin D test includes three lancets and a collection tube. To use your test kit, follow these instructions:

  • Wash your hands with warm, soapy water. You might find it more difficult to do the test if your hands are cold
  • Dry your hands thoroughly
  • Use one of the swabs included in the kit to clean the fingertip that you would like to use. We recommend that you use the middle or ring finger of your non-dominant hand (not the one you write with). Wait until the finger feels dry
  • Twist and remove the purple sticks from one lancet, place it in the middle of your fingertip, and press the purple button at the end
  • A small drop of blood should start to form on your fingertip. Don’t worry if this doesn’t work the first time as there are three lancets included with your kit
  • Use a clean tissue to wipe the first drop of blood away, then angle your finger downwards and massage the sides of your fingertip to form another drop of blood
  • Use your other hand to squeeze the fingertip to drop the blood sample into the collection tube. You should fill the tube to the upper line. If you can’t get enough blood to fill the tube, use the additional lancets on another finger and repeat steps three to seven
  • Use the plaster included in the kit to cover your fingertip
  • Put the lid on to the collection tube and turn it upside down and back several times
  • Place your details on the sticky label. This is an important step as our partner lab won’t be able to do your test otherwise. Place the labelled collection tube into the protective wallet, and the wallet into the prepaid envelope

How the results work

Your test kit will be sent to one of our partner labs. They’ll analyse and process your sample one to two days after your test kit reaches them, so you should get your results back quickly.

Your results will say one of three things: you have a normal level of vitamin D, you have an insufficient level of vitamin D, or you are deficient in vitamin D.
