What do we measure?: We use state of the art LC-MS/MS methods to measure Vitamin D in your blood. We report total and D2 and D3 levels together with a clear interpretation.

Results: Sent to the email address provided on the consent form. If you would prefer, we can post results to you. Our result form has a clear interpretation of your Vitamin D level. Results are expressed as nmol/L. See our Questions and Answers page for how to convert nmol/L to ng/mL which are the older units still used in the US and some laboratories in the UK.

Continuous Quality Improvement: The process of continuous quality improvement is key to all we do. We welcome feedback on any aspect of our Vitamin D Blood Spot Service. Our laboratory has been accredited by CPA for many years and has recently been assessed by UKAS to the ISO 15189 standards.
