SDMA, or Symmetric Dimethylarginine, is a naturally occurring compound in the body that is produced during the breakdown of arginine, an amino acid. It is primarily used as a biomarker to assess kidney function, as elevated levels of SDMA can indicate reduced kidney efficiency. Unlike other markers, SDMA is not influenced by muscle mass, making it a reliable indicator for various populations. Measuring SDMA levels can help veterinarians and healthcare providers detect kidney disease earlier than traditional methods. This early detection allows for timely intervention and management, improving outcomes for patients with kidney-related issues.
