As part of an ongoing, long-term study on the reproductive ecology and health status of imperial cormorants (Phalacrocorax atriceps), blood samples were collected to establish baseline values for hematologic parameters (hematocrit, red and white blood cell counts, leukocyte profile, heterophil:lymphocyte ratio, total solids) and serum chemis tries (glucose, uric acid, urea, total protein, triglycerides, cholesterol, albumin:globulin ratio
, alkaline phosphatase, lactate dehydrogenase, creatine phosphokinase, aspartate aminotransferase, alanine aminotransferase, calcium, phosphorus).
2002): in juvenile loggerhead sea turtles captured in offshore waters of South Carolina, Georgia, and Florida, significant correlations were observed between [summation]PCB concentrations and increased BUN concentrations and a decreased albumin:globulin ratio
In conditions such as nephrotic syndrome, the serum albumin and the albumin:globulin ratio are low.
Saline-diluted serum retains a constant albumin:globulin ratio, and alteration of this ratio is known to affect the Ektachem 700XR method (9-12).
It has been stated that prealbumin should be included in the calculation of the albumin:globulin ratio (10,31,32) and that it can act as a negative acute-phase reactant; (13) however, because the role of prealbumin in the psittacine immune response could be species-specific and is as yet unclear, (13) prealbumin was not evaluated in this study.
36) The avian tuberculin testing study also reported that hemolysis and lipemia might cause artifactual decreases in the albumin:globulin ratio and an increase in the beta globulin fraction.
Albumin:globulin ratios were also calculated for each bird.
Albumin, [alpha]-1 globulin, [beta]-globulin, and [gamma]-globulin fractions, as well as albumin:globulin ratios were similar among tinamou and most psittacine species.
