Why it matters
B12 is absorbed in the lower gut, so a low value can signal a gut or microbiome problem. It is one of the more directly supplementable findings, which makes it worth watching.
Reference ranges reflect conventional laboratory intervals. Always interpret against your own lab's printed range and your veterinary surgeon's judgement. A brighter optimal band is shown only where a published guideline defines one, and it is cited.
