Background: Serum or plasma protein electrophoresis is used as a routine test for health assessment in veterinary medicine, but there are only a limited number of studies regarding clinical use of electrophoresis in reptile species.
Objective: The goals of this study were to establish reference intervals for plasma protein electrophoresis in the Green Iguana (Iguana iguana), compare values between males and females, and to identify season-related changes.
Methods: Plasma samples were obtained from 21 healthy captive male and female Green Iguanas. Agarose gel electrophoresis was performed using an automated Hydrasys system.
Results: Four main protein fractions were observed: albumin, α globulins, β globulins, and γ globulins. Bisalbuminemia was observed in 4 of 21 healthy iguanas. Minimum and maximum values were reported for healthy Green Iguanas in March, June, September, and December. Seasonal changes in albumin were determined between March and December, and in γ globulins between June and September. Differences between males and females were seen in albumin concentration in September.
Conclusions: Reference intervals of the plasma protein fractions according to electrophoresis in the Green Iguana can be affected by seasonal changes and sex of animals. It should be taken into account when clinical evaluation is performed.
