When the collection is by vacuum tube,the coagulation tube should be collected second to avoid artefactual shortening of coagulation assays due to the trauma of venesection. When syringes are used, have ready two plastic syringes. A butterfly needle may be used. Withdraw 5 mL blood into the first syringe and discard the syringe (or use it for other tests). With the second syringe, withdraw the required amount of blood for the coagulation tests.
