Since hemolysis has been a common problem in submitted ratite serum samples, a study was performed to determine interference by hemolysates. Nine chemistry analytes including glucose, total protein, albumin, creatine kinase (CK), gamma‐glutamyl transferase (GGT), aspartate aminotransferase (AST), calcium (Ca), phosphorus, and uric acid were evaluated on a wet reagent analyzer (Ciba Corning Express 550) and on a dry slide reagent analyzer (VetTest 8008). In emus, increasing hemoglobin concentrations increased total protein, albumin, and CK for both analyzers. With increasing hemoglobin concentrations, the Ciba Corning 550 analyte values were increased for AST, Ca, and uric acid and decreased for glucose and phosphorus; the opposite effect was seen in values from the VetTest 8008. GGT levels were variable or sometimes undetectable. Changes in ostrich analytes with hemolysis were similar to emus using the same analyzer. The effects of serum hemolysis often differed in magnitude and direction between the two chemistry analyzers. Interferographs were constructed to aid in rapid assessment of the effects of hemolysis on submitted serum samples.
