Reference intervals for biochemical analytes in serum and heparinized plasma and serum protein fractions in adult alpacas (Vicugna pacos).

Background: Species-specific reference intervals for laboratory tests are required for diagnosis and management of disease. Few reports of reference intervals for biochemical analytes and protein fractions are available for alpacas.

Objectives: The aims of this study were to establish reference intervals for biochemical analytes measured in both serum and plasma and in serum protein fractions, and to determine the influence of herd and sex on test results in a population of alpacas.
