Blood collection kit - cattle/sheep/goats/horses This kit comes complete with a syringe, 18G x1" needle and either a purple top EDTA blood collection tube or red top SERUM blood collection tube. These are the items we prefer when collecting blood samples for the following tests: Pregnancy tests, health screenings, other testing required by your Vet/breed association/testing lab. *Please note, due to limitations from our distributors the syringe sizes may vary but will always be a minimum of 3CC syringe, please select the correct size/color blood tube.* *Please verify the blood tube color and amount of blood required with the lab you are submitting your sample for testing.*
