Technique to collect blood- Requirements include animals, anesthetics, cotton, 22G needle, hair remover, and blood sample collection tubes. The filled tube is then removed, and another can be inserted and filled in the same way. When a tube is inserted into the holder, its rubber cap is pierced by this inner needle, and the vacuum in the tube draws blood through the needle into the tube. Unless otherwise stated in the list of services, these samples must be collected in a standard gel-free blood collection tube (red top).

(Technique to collect blood)
Blood collected with an anticoagulant suitable for the test described cannot be considered suitable for other tests. Hemolysis occurs when the thin protective membrane that encloses the fragile red blood cells is ruptured, allowing hemoglobin to escape into the plasma. As hemolysis affects many procedures, please submit samples that are as free of hemolysis as possible. During centrifugation, a gel barrier is formed between the plasma and the cellular components of the blood.
Since additives are not interchangeable, it is necessary to consult the sample requirements section of the individual test descriptions to determine the appropriate collection requirements for the ordered test.
