What is SDMA?

SDMA is a more reliable indicator of kidney function than creatinine.1-5 A renal biomarker specific to kidney function, SDMA has proven to be a more sensitive indicator than creatinine, enabling veterinarians to detect acute kidney injury and chronic kidney disease earlier than ever before. 1-3,5

Why is SDMA more reliable?

SDMA is more reliable than creatinine because of its 3 key attributes:

  • SDMA is a biomarker for kidney function.
  • SDMA increases earlier than creatinine.2,3
  • SDMA is specific for kidney function and less impacted by extrarenal factors, including body condition, advanced age, and disease state.4,5

IDEXX SDMA: The standard of care for assessing kidney function

Take action with SDMA

An increased SDMA indicates decreased kidney function as a result of acute kidney injury (AKI), chronic kidney disease (CKD), or both. It requires further diagnostic investigation. SDMA results above the reference interval mean you should take action to investigate, manage and monitor.

STAGING GUIDELINES

The International Renal Interest Society (IRIS), led by a board of 15 world-renowned independent veterinarians specializing in nephrology, added SDMA to their guidelines.6
