  2. Definition

    This codelist was taken from OpenCodelists, created by OpenSAFELY. We recommend viewing this Phenotype on the OpenCodelist website to view the most recent version.

    A SNOMED CT codelist to identify people who have received a blood test to assess vitamin D deficiency status.

  3. Methodology

    We searched for the terms "25-OH", 'vit d' and 'vitamin d' to generate a list of codes to review. We removed codes which were explicitly related to vitamin D2 or vitamin D3 alone, 1,25-hydroxyvitamin D or which did not have the 'observable entity' SNOMED CT classification.
