Cardiac puncture is a suitable technique to obtain a single, large, good quality sample from a euthanised guinea pig or a guinea pig under deep terminal anaesthesia if coagulation parameters, a separate arterial or venous sample or cardiac histology are not required. It is appropriate for all strains of guinea pig.
A sample of 1-25 ml of blood can be obtained depending on the size of the guinea pig and whether the heart is beating. Blood samples are taken from the heart, preferably the ventricle, either via a thoracotomy or the left side of the chest. Blood should be withdrawn slowly to prevent the heart collapsing.
