SDMA: Innovative kidney function biomarker
Three key attributes of SDMA make it a more reliable kidney function test:
- Biomarker for kidney function
SDMA is excreted by the kidneys. SDMA more accurately reflects glomerular filtration rate (GFR) in dogs and cats.1-3,7
- Earlier than creatinine
SDMA increases as early as 25% loss of kidney function,2 making SDMA more reliable in both acute or active kidney injury and chronic kidney disease.1-3 Creatinine cannot identify kidney issues until almost 75% of kidney function is lost.2,3
- Specific for kidney function
SDMA is less impacted by extrarenal factors than creatinine, including body condition, advanced age, and disease state.4,5
SDMA is also not affected by lean body mass, making it more reliable for assessing kidney function in animals with chronic kidney disease or other conditions that result in weight and muscle loss, such as hyperthyroidism.4,5
The IDEXX SDMA Test is now included in the International Renal Interest Society (IRIS) Chronic Kidney Disease (CKD) Staging and Treatment Guidelines as a useful adjunct for diagnosing CKD and for helping to determine treatment for the appropriate stage of CKD.6
Simple to order
The IDEXX SDMA Test is included in all IDEXX Reference Laboratories routine reference laboratory chemistry panels at no additional charge. It can also be easily ordered as a stand-alone test to complement your in-house IDEXX chemistry panel.
