Bella’s own range 6.8–15.2 · 3 previous readings · from published biological variation · provisional
SDMA has risen 44% over 1.4 years but remains within its reference range: a direction worth watching. That is more than SDMA's expected biological variation (reference change value 39%).

Why it matters
Kidneys
Where SDMA is read: the kidneys.
SDMA is the earliest routine marker of declining kidney filtration: it rises before creatinine and before symptoms. A steady climb over successive readings, even within range, is worth discussing with your vet.
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.
