Describe the differences in technique used for sample collection of routine venous blood
  samples and those used for coagulation studies.

Question 2

State appropriate venipuncture and arterial puncture sites of all large animal species.

Answer to Question 1

Collection of a quality blood sample for coagulation studies requires a clean, atraumatic
technique. Inadvertent trauma to vessels or blood during collection will activate the clotting
cascade and induce platelet adhesion, thus rendering the sample useless. To minimize trauma,
a two-syringe technique is used. This technique involves collecting 1 cc of blood and then
exchanging syringes while the needle remains in the vessel. Once the second syringe has been
attached to the original needle, the sample is collected.

Answer to Question 2

SPECIES: Horse, Cow, Pig, Llama, Goat
Venipuncture locations
Jugular, horse
Facial sinus, horse
Jugular, cow
Coccygeal, cow
High-neck Jugular, llama
Low-neck Jugular, llama
Jugular, goat
Jugular, sheep
19
Jugular, small pig
Jugular, large pig
Marginal ear vein, pig
Arterial puncture locations
Carotid, facial, transverse facial, and greater metatarsal, horse
Coccygeal, median auricular, cow
Note that the cephalic vein (horse) and the lateral thoracic or milk vein (cow) are not
recommended for blood draws.
