Selected complete blood cell count and plasma protein electrophoresis parameters in pet psittacine birds evaluated...

Veterinarians rely on results of both the complete blood cell count (CBC) and plasma protein electrophoresis (EPH) in conjunction with the results of the plasma biochemical analysis to evaluate the health status of avian patients. Because the CBC and protein EPH measure different aspects of the immune response to disease, both tests are recommended in avian patients to rule out infectious or inflammatory disease. To evaluate results of the CBC and protein EPH in pet psittacine birds, the records of 144 pet psittacine birds, comprising 11 genera, that were presented for suspected illness were reviewed. Results of the CBC (total white blood cell count and packed cell volume) and protein EPH (alpha, beta, and gamma globulin concentrations) from submitted blood samples from each bird were evaluated. Of the 144 birds, 63 (43.8%) had abnormal CBC results, and 25 (17.4%) had abnormal EPH measurements. Results of the CBC and protein EPH were within reference ranges in 73 birds (50.7%). Abnormal results of the CBC in conjunction with normal EPH results were present in 46 birds (31.9%), compared with 8 birds (5.6%) with normal results of the CBC and abnormal EPH results. The findings of this study could aid practitioners in evaluating psittacine patients and prioritizing the value of individual diagnostic tests.
