Typical reference range

138–650 pmol/l

Reference ranges vary between labs and by age, sex, and method — always read your result against the range printed on your lab report.

Educational only — not medical or diagnostic advice. One marker is a single data point; interpret it alongside your history and other results, and consult a qualified clinician about your health.

Track your Vitamin B12 over time in Quanome — it reads your lab reports (PDF or photo) on your device, charts each marker against its range, and an AI coach explains what your trends mean alongside your Apple Health and DNA.
