Lizard Blood Values

Baseline haematology and biochemistry values of 'normals' must be established per patient and per laboratory. It is very useful to establish normals for individual patients at the time of regular health checks before the animals are presented for sickness. Values may vary depending on season, breeding condition and diet. The following values have been taken from various sources and reflect the laboratory methods as well as the individual species. Caution is advised when using these values for the interpretation of your own patients' blood results.

Normal haematology & plasma biochemistry values in the green iguana (Iguana iguana)

Ten wild caught iguanas were blood sampled as part of a health assessment prior to introduction to an existing group. The iguanas were manually restrained by holding the forelimbs laterally against their chest and the hindlimbs against the tail. Blood was collected from the ventral tail vein and placed in lithium heparin. A fresh blood smear was made at the time of collection. Urea, creatinine and LDH were considered poor diagnostic parameters.
