==Blood samples==

When collecting blood samples, fill tubes containing anticoagulant to the fill line and mix gently immediately after collection. Vacutainers can be used for large animal blood sample collection, and a needle and syringe for small animals. The jugular vein is the preferred collection site using a wide bore needle to prevent haemolysis of the blood from using excessive suction during collection. The Cephalic and Saphenous veins are alternative venipuncture sites. Ensure the venipuncture site is clean and swabbed, wear gloves and ensure you have adequate restraint prior to collecting a blood sample.

Always label your sample tubes with permanent marker immediately with the animal's details and the date and time of collection. Serum samples can be processed by allowing the blood to clot in an upright position and removing the serum from the tube prior to sending the sample for analysis to avoid haemolysis (bursting of the red blood cells into the serum) during transit. A more ideal method of serum separation is to centrifuge the sample -balance the centrifuge by adding a tube filled with the same volume of fluid in the opposite well in the centrifuge for safety.
