Vitamin B12

Core panel — run every month

What it indicates

A vitamin involved in nerve function and in the formation of red blood cells.

Why a series helps

It changes slowly with intake, so a series shows direction rather than a moment.

What this page does not tell you

What a particular Vitamin B12 result means depends on you: your history, your medication, why the test was taken. Ziro does not interpret results for individuals and does not diagnose. If something in your results warrants a conversation, that conversation is with a doctor, and your results are downloadable so you can bring them.
