Data are from the 1st serum biochemistry performed on each horse. Reference range provided is a general range from the New York State Animal Health Diagnostic Center. Tests were run at multiple laboratories and laboratory‐specific reference ranges varied.
Abbreviations: AST, aspartate aminotransferase; GGT, gamma‐glutamyltransferase.
