Plasma chemistry in peregrine falcons (Falco peregrinus): Reference values and physiological variations of importance for interpretation.
Reference values (inner limits of the percentiles P(2.5) and P(97.5) are given with a probability of 95%) for 21 plasma chemical variables were established in 79 peregrine falcons (Falco peregrinus). The following values were established: urea 0.8 to 3.9 mmol/l, creatinine 24 to 64 mumol/l, glucose 16.5 to 22.0 mmol/l, sodium 150 to 170 mmol/l, chloride 114 to 131 mmol/I, inorganic phosphorus 0.55 to 1.53 mmol/l, osmolal-ity 322 to 356 mOsmol/kg, alkaline phosphatase 31 to 121 IU/l, alanine aminotransferase 29 to 90 IU/l, aspartate aminotransferase 34 to 116 U/l, gamma glutamyl transferase 0 to 3 IU/l, lactate dehydrogenase 1008 to 2650 IU/l, creatine kinase 120 to 442 IU/l, cholinesterase 143 to 325 IU/1, glutamate dehydrogenase < 8 IU/l, total bile acids 5 to 69 mumol/l, uric acid 253 to 995 mumol/l, total protein 24 to 39 g/l, albumin 12.7 to 22.4 g/l. Reference values for the calculated albumin/globulin (A/G) ratio were 0.8 to 24. Based on previous studies, reference values for calcium were established using an adjustment formula using plasma total protein concentrations (before correction 1.86 to 2.49, after correction 1.97 to 2.46 mmol/l). Results of plasma potassium concentrations were erratic which was shown to be due to a time lag between sample collection and separation of plasma and cells.
