Direct to the public Vitamin D

testing from our NHS


A finger-prick blood spot sample - not the larger more difficult to collect micro samples seen with other services. Our LC-MS/MS machines give results for Total Vitamin D and also D3 and D2 levels. We are the UK’s original public service. You can take too much vitamin D. We phone people every week advising of potentially toxic levels of vitamin D due to supplement overuse. Early side effects can include gastrointestinal changes and discomfort. See NHS advise on toxicity and maximum oral doses here…. Secret Shoppers: Recent secret shoppers show the laboratory turn-round to be excellent. See the results people get with our test here - here.

Our service to the public

We are the UK’s original vitamin D public testing laboratory, providing a service since 2011. We are also one of the largest vitamin D testing laboratories in the NHS. Our test pack includes everything required to take a sample and send back for analysis. Clear instructions enable you to take the finger-prick sample. A very small amount of blood is required compared to alternative approaches. You return your sample and consent form in a pre-paid envelope. Results are sent back by email as a PDF, or by post if you prefer. Our service is used both by the public and by researchers studying Vitamin D in the UK and around the world.

How it works….

UK orders include reply postage. Overseas orders - you add the postage . Results are compared to NHS reference intervals used to interpret if you have enough vitamin D or need to take an oral supplement. Our LC-MS/MS machines measure D3 and D2, to give a ‘Total vitamin D’. Please purchase test kits using links above. We also supply professionals with bulk packs - 10s and 50s, at discounted rates. You can also order these if you are testing your extended family, workplace, nursing home, etc. Prices are inclusive of postage.
