Clinicians need to consider analytical issues when requesting and interpreting these tests

Vitamin B12 and folate tests are useful for identifying patients with a deficiency. In this issue of the Journal, Willis and colleagues highlight some of the limitations of serum vitamin B12 assays.1 They also emphasise the uncertainty regarding whether red-cell or serum folate should be the preferred first-line test for folate status. The issues underlying some of the data presented require elaboration.
