Run SDMA every time you run creatinine and BUN
A new standard of care for monitoring kidney function that detects and reflects disease
- SDMA is a sensitive indicator of kidney function that detects as little as 25% loss of function.1,2
- SDMA is more reliable than creatinine as an indicator of kidney function because it is not influenced by confounding conditions.4,5
- SDMA is an earlier indicator of progressive kidney function loss, often increasing before other parameters.1–3
- An increased SDMA may also serve as an indicator of concurrent disease that may have a secondary impact on kidney function.6
What to do when SDMA is increased
An increased SDMA indicates impaired GFR, which helps detect both acute and chronic diseases within the kidneys or reflects secondary diseases causing a negative impact on kidney function.
The IDEXX SDMA Test Algorithm will help you take the appropriate steps towards confirming disease and diagnosis when SDMA is increased.
When SDMA is increased, but all other markers are normal, don't hesitate.
Take action: Investigate, manage, and monitor. Get the details.
Follow the IRIS guidelines for staging and treating CKD
The International Renal Interest Society (IRIS) chronic kidney disease (CKD) guidelines recognize the importance of SDMA for both diagnosis and treatment.7
Two options: same reliable results
