Heparin Tube aims to obtain plasma specimen, which is used not only for emergency biochemistry tests but also for blood rheology test. Inside the tube wall, where is well sprayed with lithium heparin or sodium heparin which is a kind of anticoagulant activating antithrombins to block the coagulation cascade reaction.
Gel & Heparin Tube is a kind of anticoagulation tube, aims to obtain high quality plasma specimen for fast emergency biochemistry test. Lying at the bottom of the tube, there is some gel for separating plasma and blood cells, preventing substance from exchanging and keeping the obtained plasma from being blood cell polluted, thus the accuracy of the results will be improved. Otherwise, the specimen could be put into the equipment directly without transferring and kept stable in cold storage for 72hs, so that well meets the quality requirement of retest.
