The sites for obtaining blood samples in snakes include the ventral tail vein, the palatine vein and cardiocentesis.  Restraint is by gentle, careful handling or by chemical means. Asepsis is extremely important during blood collection and the site of collection should be prepared as if for surgery. Prior to collection it is important to have all materials and equipment ready: cotton wool, antiseptic (chlorhexidine or a povidone-iodine detergent), needle and syringe of suitable sizes, and the blood handling materials.
