PAIRED BIOCHEMICAL ANALYSIS OF PIGMENTED PLASMA SAMPLES FROM ZOO-KEPT AMERICAN FLAMINGOS () USING A POINT-OF-CARE AND A STANDARD WET CHEMISTRY ANALYZER.

American flamingos () are commonly kept in zoological collections, making health monitoring essential. Use of point-of-care (POC) blood analyzers that require small volumes of whole blood samples produces prompt results allowing for rapid clinical decision-making. To evaluate and compare blood biochemistry analysis results analyzed by a POC biochemistry analyzer and a laboratory wet biochemistry analyzer, blood was collected from 17 apparently healthy zoo-kept American flamingos. Analyzer agreement was investigated using the Passing-Bablock regression analysis and Spearman correlation coefficients. Plasma samples from all birds were bright yellow in color. The results from the POC analyzer used in this study were found to be outside acceptance and clinical allowable error limits when compared with the laboratory analyzer for phosphorus (Phos), total protein (TP), albumin (Alb), glucose (Glu), creatine kinase (CK), and potassium (K). For aspartate aminotransferase (AST), results were within clinical allowable error but outside the acceptance limits, and for calcium (Ca) and sodium (Na), results were within both limits. The POC analyzer failed to measure the uric acid (UA) concentrations of all the samples, and reported all bile acids (BA) concentrations as below its minimal measurable limit. The use of analyzer-specific reference intervals is recommended for most analytes tested. The POC analyzer used in this study cannot be recommended for measuring UA concentrations in brightly colored samples from American flamingos.
