Which biomarker is included in baseline renal screening for senior dogs?

Explanation:
Baseline renal screening in older dogs focuses on a marker that best reflects kidney function, especially glomerular filtration rate. Symmetric dimethylarginine (SDMA) is included because it correlates with GFR and tends to rise earlier than creatinine as kidney function declines, allowing earlier detection of kidney disease. It’s also less affected by muscle mass, which helps in aging dogs that may have muscle loss. In contrast, ALT and ALP are liver enzymes, not kidney indicators, and CK is a muscle enzyme associated with muscle injury, not renal status. So, SDMA is the most informative biomarker for baseline renal screening in senior dogs.
