Cardiac puncture is a suitable technique to obtain a single, large, good quality sample from a euthanised ferret or a ferret under deep terminal anaesthesia if coagulation parameters, a separate arterial or venous sample or cardiac histology are not required.
A sample of 20 ml of blood can be obtained depending on the size of the ferret and whether the heart is beating. Blood samples are taken from the heart, preferably the ventricle, which can be accessed either via the left side of the chest, through the diaphragm or by performing a thoracotomy. Blood should be withdrawn slowly to prevent the heart collapsing.
