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 lithium heparin or sodium heparin. The anticoagulant heparin activates antithrombins, thus blocking the coagulation cascade and producing a whole blood/ plasma sample instead of clotted blood plus serum. Validates that through its special treatment, most of the plasma indexes can be repeated within 6 hours, especially for such sensitive ones as AST, ALT, TBIL, DBIL and GGT.
