Reference hematologic and plasma chemistry values of brown tree snakes (Boiga irregularis)

Reference hematologic and plasma chemistry values were determined from 103 blood samples collected from 53 clinically healthy brown tree snakes (Boiga irregularis). Female snakes had significantly higher mean plasma values fo r total solids, total protein, calcium (Ca), phosphorus (P). uric acid. and blood monocyte percentage than did males, whereas males had significantly higher mean plasma fibrinogen values. The variances for hematocrit, monocyt e percentage, azurophil percentage, plasma total solids, plasma total prote in, albumin, Ca, and P also differed significantly between sexes. The highe r mean values and greater variances for plasma total protein, plasma total solids, Ca, and P in the female snakes were probably associated with yolk s ynthesis and accumulation.
