Symmetric dimethylarginine concentrations in healthy neonatal foals and mares

Background Symmetric dimethylarginine (SDMA) is a renal biomarker correlated with glomerular filtration rate (GFR). Objectives Describe changes in SDMA in clinically healthy foals and their mares during the first month postfoaling. Animals Convenience sampling of healthy periparturient Thoroughbred mares and their full‐term foals from a population of client‐owned horses. Methods Serum and EDTA whole blood samples were collected from mares in their last month of pregnancy and then from mares and foals at approximately
