  • Vitamin D Test

Vitamin D (25-OH) deficiency test

Blood Spot Laboratory Service - available in the UK only


A vitamin D blood test can help identify whether you are vitamin D deficient. Vitamin D is obtained from two sources; around 90% from sunlight and 10% from foods.  In winter, it can be difficult to gain sufficient vitamin D from exposure to sunlight. Vitamin D is an important nutrient for a healthy skeletal and immune system. The test measures the total amount of 25-OH Vitamin D2 and 25-OH Vitamin D3 in the blood which is an appropriate indicator of body stores.

A scientific study published in 2016 showed that capillary blood measurement of Vitamin D status by finger prick sampling has excellent correlation with venous samples.

How the test works

Once you have placed your order we will send you a blood spot collection kit that allows you to simply and safely collect a few drops of blood from your finger tip in the comfort of your own home and return your sample to us for analysis. There are no additional costs.

The procedure is simple but please read the instructions included with your collection pack.

The pack includes;

  • Test Request Form
  • 2 finger prickers
  • blood collection tube for vitamin D analysis
  • pre paid packaging to send your sample to our laboratory

Your results

Once your blood sample has been received by our laboratory, the sample will be tested within 1 to 2 days. You will receive your results by post together with a review and follow up advice from our doctor.

  • Turnaround time is 1 to 2 days from the day we receive your sample

Further information

Our regulated self test kits are a convenient, reliable and quick way to obtain a test result for a specific medical condition. Nevertheless, our best advice is to encourage you to use existing healthcare pathways wherever possible.

Whether you have a positive or a negative result with a self test kit, always speak with your GP if you are concerned about your symptoms.
