There are different types of additives and tests for the different colors of the caps and labels of the standard blood collection tubes, so you can request the corresponding test tubes for the purpose of selection.
1 Red head cover tube (dry vacuum tube without additives)
The inner wall of the sampling and infiltration is evenly coated with agent (silicone oil) to prevent hanging on the wall. It uses the principle of natural blood and blood to make voice singing, etc., after natural analysis, centrifugal use. Amylase, etc.), protein (including potassium, sodium, chloride, calcium, phosphorus, etc.), text function, drug detection, camera detection, tumor markers, clear visualization.
2Orange-red head cap tube (coagulation tube) (this is indeed orange-red, but it is very similar to the above)
The inner wall of the blood collection tube is uniformly coated with anticoagulant and wall-mounted silicone coagulant, which promotes the polymerization of fibers, so that the fibrin fibers that are not coagulated at the same time are aggregated to form a stable clot. When you want to get the results quickly, you can use a coagulation tube, which usually produces a breath within 5 minutes. For general emergency biochemistry.
3 golden cap tube (contains the intake of inert alcohol and coagulant)
The tube wall is siliconized and coated with a coagulant to accelerate the entrance of blood and check the inspection time. Separating glue can form the liquid component (skin) and cell component (blood cells) of the blood separately and gathered in a test tube. There are no oil droplets in the post-centrifugation process, so the machine will not be blocked. Mainly used for nursing control of biochemistry (liver). , Kidney function, cartilage enzymes, amylase, etc.), particles (power plating, sodium, chloride, calcium, phosphorus, etc.), nail function, drug detection, explosion detection, tumor markers, PCR, TORCH, reflector immune detection, etc.
4Green cap tube (heparin anticoagulation tube)
Contains a kind of vitamin sodium or heparin sodium. Heparin is a viscous polysaccharide that replenishes the matrix mass and carries negative liver energy. It has the effect of strengthening antithrombin and inactivating serine, thereby preventing digestive enzymes. Formation, the liver tube is generally used for the detection of acute biochemistry, torch, and blood rheology testing. When testing sodium ions in the blood, heparin sodium nanotubes cannot be used, which quickly affects. Used for white blood cell counting and classification, because heparin can cause white blood cell aggregation.
5Purple cap tube (containing ethylenediamine tetra and its salt)
Ethyleneditetramine is a post-polyarcyl acid that can effectively chelate calcium ions in the blood. The chelation of calcium and calcium from the point shift reaction will prevent and terminate the endogenous or exogenous pregnancy process, thereby leading to prevention Compared with other anticoagulants, the opinion of blood cells mainly affects the agglutination and morphology of cells, so EDTA salts (2K, 3K, 2Na) are usually used as anticoagulants. Frequently) inspections and blood cannabis testing. It cannot be used for blood coagulation and trace element inspection.
6 blue cap tube (contains sodium sodium anticoagulant)
Satellite sodium polymerizes with calcium ions in the blood sample to act as an anticoagulant. The concentration of anticoagulant and blood is 1:9. It is mainly used in the fibrinolytic system (prothrombin time, thrombin time, activated partial thrombin time, fiber) ( Proprotein). Pay attention to the sufficient amount of 2ml when collecting blood to ensure the accuracy of the test results. The blood mixture should be inverted 8-10 times immediately after collection.
7 black cap tube (contains 0.109mol/L sodium sodium)
The volume ratio of the coagulant to blood is 1:4, which is generally used for erythrocyte sedimentation rate detection. When the anticoagulant reflection is too high, the blood is collected at the stage of hot erythrocyte sedimentation. (2ml), in order to verify the accuracy of the results, the blood should be poured and mixed 8-10 times immediately after the blood is collected.
8 dust head cap tube (contains potassium oxalate/sodium fluoride)
Sodium fluoride is a weak anticoagulant, has a good anticoagulant effect, and is an excellent preservative. When using it, pay attention to slowly inverting the color mixing. Corn can not be used to detect inorganic phosphatase and amylase.
