In reptiles the total blood volume varies with species but is approximately 5-8% bodyweight. The maximum that can be drawn safely is 10% of the total blood volume. A 100 g reptile can therefore have 0.5 ml safely taken. (Weigh accurately and make the calculations before blood is withdrawn!). Though microtechniques for biochemistry are available in some laboratories, it is generally advisable to take 1.5 ml of blood for complete [[Lizard and Snake Haematology|haematology]] and [[Lizard and Snake Biochemistry|biochemistry]].
