Why this test
Low B12 is associated with changes in nerve and cognitive function. It is one of several causes a GP can look into when those symptoms come up, since these symptoms are often not specific to B12.
Serum B12 measures the B12 circulating in your blood, not how much is reaching your cells. One Australian clinical guide treats results between 133 and 258 pmol/L as indeterminate, which is the band sometimes called the grey zone. Cut-offs vary between laboratories, and some Australian laboratories treat results up to about 330 pmol/L as equivocal, so always read your result against the interval printed on your own report. If symptoms persist and your result sits in this band, your GP may add MMA, homocysteine or Active B12 for more context.

Yes. Your Clarity Labs Vitamin B12 test reports both serum (total) B12 and Active B12 (holotranscobalamin) — the fraction bound to transcobalamin that your cells can actually take up and use. Active B12 is the first-line B12 assay at our accredited Australian lab, so both numbers come back from a single order.

Yes. If you are already taking B12, tell your GP before the test. A supplement can lift the number in your blood without fully correcting a shortfall, so the result needs to be read with that in mind. Testing shows your B12 level at the time of collection, which your GP can read alongside your diet, medicines and symptoms.
No fasting is required for B12 testing.
Grey zone is an informal name for the indeterminate band, where a serum B12 result is neither clearly low nor clearly adequate. One Australian clinical guide places that band between 133 and 258 pmol/L. Cut-offs vary between laboratories, and some Australian laboratories treat results up to about 330 pmol/L as equivocal, so check the interval printed on your own report. In this band the number alone cannot show how much B12 is reaching your cells, so if symptoms persist your GP may add MMA, homocysteine or Active B12 for more context.
Results are typically available in 3 to 5 business days via your dashboard.
