Plastic serum tubes containing a clot activator may cause interference in coagulation testing. Only blood culture tubes, glass nonadditive serum tubes, or plastic serum tubes without a clot activator may be collected before the coagulation tube.
Can you collect blood before coagulation?
Only blood culture tubes, glass nonadditive serum tubes, or plastic serum tubes without a clot activator may be collected before the coagulation tube. Numerous errors can occur during the collection and handling of blood specimens, which pose significant and avoidable risks to the patient and the phlebotomist.
What is the order of draw in phlebotomy?

What happens when a blood tube is inverted?
When the tube position is inverted relative to horizontal, i.e., the stopper of the tube is lower than the bottom of the tube, the tube fills from top to bottom, contaminating the needle that pierces the stopper. In practice, those who draw blood samples cannot always control the orientation of the tubes as they are filled when using a tube holder.
What is a carryover in a syringe draw?
In a syringe draw, the carryover occurs with the needle of the safety transfer device. (According to OSHA, blood collected by syringe should be transferred to the tubes using a safety transfer device, not the same needle used to perform the venipuncture.)
What is additive carryover?
Additive carryover occurs when the needle filling a tube comes in contact with the blood/additive mixture as the tube fills, and transfers a minute amount of blood and additive into the next tube filled. This can occur with both syringe and vacuum draws. In a syringe draw, the carryover occurs with the needle of the safety transfer device.
Why did the order of draw change?
Whereas glass is a natural clot activator, plastic is not. So in order for blood to clot in safer plastic tubes, manufacturers coat the inside of the tube with a substance to facilitate clotting, like silica particles. However, if the tube following the clot activator tube remained the coag tube, as was the recommended order prior to 2003, carryover threatens the coag results. With the consensus of all major U.S. tube manufacturers, CLSI issued one single change in the order of draw when the venipuncture standard was revised in 2003: serum tubes that used to precede the blue-stopper coag tube were relocated to follow coag tubes. This change was only possible because a myth about tissue thromboplastin was disproved.
What is a heparin tube?
