Take blood from a bird is a tricky operation
The amount of blood to be collected remains minimal, less than 20 microliter.
Cut the nail
Cut the nail millimeter by millimeter and allow a drop of blood to flow on the paper.
Allow the drop of blood to dry completely on the paper.
Place the sample in a small plastic bag, such as a freezer bag.
We recommend that the sample be taken by a veterinarian. If the bird bleeds a little bit, you can apply a coagulant like hydrogen peroxide or aluspray available in your pharmacy or veterinarian.
