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’
