Heparin Tube

Heparin Tube is used in blood collection and anti-coagulation not only for routine clinical biochemistry tests and emergency biochemistry tests but also for some test items in blood rheology. It is coated with heparin lithium or heparin sodium . The anticoagulant heparin activates antithrombins,thus blocking the coagulation cascade and producing a whole blood/ plasma sample instead of clotted blood plus serum. Soon after the sampling, turn the tube 180°upside down,shaking and mixing 5-6 times.Heparin Anticoagulation Blood sample should be used within 6 hours after sampling, otherwise, the blood will coagulate again.
