Heparin sodium blood collection tube has a great effect
BD heparin sodium blood collection tube contains heparin sodium or heparin lithium, heparin is a kind of mucopolysaccharide containing sulfate group, with a strong negative charge, it has the effect of strengthening antithrombin III inactivation of serine protease, thereby preventing thrombin. It 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.
The color of BD heparin sodium blood collection tube is green:
Heparin is added to the blood collection tube. Heparin directly has the effect of antithrombin, which can prolong the coagulation time of the specimen. Excessive heparin will cause the aggregation of leukocytes and cannot be used for leukocyte counting, because the background of the blood film will appear light blue after staining. , so it is not suitable for leukocyte classification. The sample types are whole blood and plasma; purposes: red blood cell fragility test, blood gas analysis, hematocrit test, erythrocyte sedimentation rate and general energy biochemical determination.
BD heparin sodium blood collection tube is suitable for clinical biochemistry. The inner wall is evenly sprayed with aerosol lithium heparin, heparin sodium or heparin ammonia, and each milliliter of blood contains 18IU of heparin. The unique anticoagulant spraying process makes the anticoagulant work best. The plasma tube with separating gel can obtain heparin anticoagulated plasma after centrifugation to meet more clinical needs. BD venous vacuum blood collection system is a complete closed blood collection system consisting of three parts: sterile vacuum blood collection tubes with preset blood collection volume and additives, different types of blood collection needles and needle holders that can meet various needs. The birth and application of this system can effectively reduce the pre-analytical errors of specimens and improve the accuracy of testing; it also provides safety protection for patients and medical staff, and reduces nosocomial infections. BD heparin sodium blood collection tubes 367878 and 367874 are used to separate plasma after venous blood collection, and are used in clinical biochemical tests.
