1、 Serum separation tube
The inner wall of blood collection tube is evenly sprayed with procoagulant to accelerate blood coagulation and shorten the turnaround time (TAT). Emotional separation gel is used to separate blood cells and serum after centrifugation, which can improve the serum yield and maintain the stability of serum components for a longer period of time, which is conducive to the retesting of samples. The separation gel is stable and less likely to adsorb proteins in the serum, giving true results for drug testing and general biochemical assays.
Plasma Separation Tubes
Empty blood tubes contain an inert separator gel that separates blood cells from plasma, improves plasma yield, and maintains the stability of plasma components. It is used to collect plasma samples, eliminating clotting time and reducing turnaround time (TAT). Usually used for intensive care and emergency testing.
3、 Serum tube
Serum tubes are used to collect venous blood and then separate out the serum. Used in clinical chemistry, serology, immunology, therapeutic drug monitoring, trace element determination. The role of procoagulants is to accelerate blood clotting. The use of procoagulant tube can shorten the turnaround time.
4、Plasma tube
Plasma tube is used to collect venous blood and then separate out the plasma, which is used in clinical biochemistry and other tests. Plasma tube wall evenly sprayed with heparin clone or heparin sodium for blood anticoagulation, suitable for most clinical biochemical testing, can be used as the main disposable blood collection tube for those laboratories that do not need to separate the tube but also need plasma specimens.
5、Glucose tube
Blood glucose tubes are used for blood glucose determination or glucose tolerance testing. The wall of the tube is evenly sprayed with anticoagulant (potassium oxalate) and glycogen stabilizer (sodium fluoride) glycogen stabilizer can keep the blood glucose concentration stable for 24 hours under the condition of room temperature.
6、EDTA blood routine tube
Blood routine tube contains EDTA dipotassium salt or tri-potassium salt, in which the dipotassium salt is sprayed uniformly on the wall of the tube in a mist. The tube is mainly used for hematological testing such as blood, hemoglobin, glycated hemoglobin, cyclocytin, red blood cell folic acid and pre-transfusion testing (blood group, antibody screening, cross-matching).
7、Hemocoagulation tube
Hemocoagulation tube is mainly used for coagulation four tests (prothrombin time, prothrombin time, activated partial thromboplastin time, fibrinogen), to guide clinical monitoring such as oral warfarin therapy, monitoring of intravenous heparin therapy and "special coagulation studies. (Coagulation factor testing, such as factor V or hemophilia factor, platelet function testing.
8、Hematocrit tube
Hematocrit tubes are used for the determination of erythrocyte sedimentation rate and contain a 3.2% sodium constructate solution for anticoagulation, with a 1:4 ratio of anticoagulant to blood. The method is a closed system and can be performed directly after blood collection without opening the cap.
