green top sodium heparin tube

As a blood anticoagulant, heparin sodium collection tubes for blood is widely used in various laboratories as an emergency department due to its good anticoagulant effect, little hemolysis and little influence on blood biochemical analysis.The function of heparin sodium sealing tube (green Blood Collection Tube)injection is to keep the intravenous injection device unobstructed, such as indwelling needles, various catheters, etc., to prevent the formation of thrombosis. In use, a sufficient dose of heparin sodium injection should be injected into the injection device to fill the entire injection device, and a new injection should be replaced before each use.

The heparin sodium blood collection tube contains heparin sodium or heparin lithium. Heparin is a mucopolysaccharide containing a sulfate group with a strong negative charge, which has the effect of strengthening antithrombin III and inactivating serine protease, thereby preventing thrombin from deactivating. Formation, and has various anticoagulant effects such as preventing platelet aggregation. Typically 15IU of heparin is used to anticoagulate 1ml of blood. Heparin tubes are generally used for emergency biochemical and blood flow detection. When testing sodium ions in blood samples, heparin sodium should not be used, so as not to affect the test results. Heparin can change the potential of red blood cells, so it is not suitable for the detection of erythrocyte sedimentation rate.
