Why it's essential to run SDMA every time you run creatinine and BUN
SDMA provides deeper insights because of its 3 key attributes
- SDMA is a biomarker for kidney function.
- SDMA increases early, with only 25% of kidney function lost.1–3
- SDMA is specific for kidney function and less impacted by extrarenal factors, including body condition, advanced age, and disease state.4,5
Common cases when SDMA is essential
When SDMA is increased and other results are normal
SDMA detected Bess' chronic kidney disease (CKD), allowing treatment to begin earlier.
Bess showed some moderate periodontal disease, and other examination parameters were within normal limits. Learn why it's important to pay attention when SDMA is increased and other factors look normal.

Two options: same reliable results
The in-house Catalyst SDMA Test for use with the Catalyst One and Catalyst Dx chemistry analyzers
The IDEXX SDMA Test, included with every chemistry panel or as a stand-alone test from IDEXX Reference Laboratories
Note: SDMA is symmetric dimethylarginine.
IDEXX SDMA medical claims are supported by extensive scientific evidence.
