Normal Reference Intervals And The Effects Of Time And Feeding On Serum Bile Acid Concentrations In Llamas, Claire B. Andreasen, Erwin G. Pearson, Brad B. Smith, Terry C. Gerros, Duane Lassen

Claire B. Andreasen

Fifty clinically healthy llamas, 0.5–13 years of age (22 intact males, 10 neutered males, 18 females), with no biochemical evidence of liver disease or hematologic abnormalities, were selected to establish serum bile acid reference intervals. Serum samples submitted to the clinical pathology laboratory were analyzed using a colorimetric enzymatic assay to establish bile acid reference intervals. A nonparametric distribution of llama bile acid concentrations was 1–23 mmol/liter for llamas .1 year of age and 10–44 mmol/liter for llamas #1 year of age. A significant difference was found between these 2 age groups. No correlation was detected between gender and bile …
