1.The common serum tube red cap collection vessel contains no additives, no anticoagulant and procoagulant components, only vacuum. Used for routine serum biochemistry, blood bank, and serological-related tests, a variety of biochemical and immunological tests, such as syphilis, hepatitis B quantification, etc., do not need to shake after drawing blood. The sample preparation type was serum. After blood was drawn, it was placed in a water bath at 37℃ for more than 30min, centrifuged, and the upper layer of serum was used for reserve.
2. There is a procoagulant in the orange head of the rapid serum tube to accelerate the coagulation process. The rapid serum tube can coagulate the collected blood within 5 minutes, which is suitable for emergency serum series tests. It is the most commonly used coagulant test tube in daily biochemistry, immunity, serum, and hormone. After blood is drawn, it can be mixed reversely 5-8 times and can be placed in a 37℃ water bath for 10-20min when the room temperature is low, and the upper serum can be centrifuged for use.
3. Inert separation glue and coagulant are added to the yellow head cap Blood Collection Tube of inert separation glue. The specimens remained stable for 48 hours after centrifugation. The procoagulant can quickly activate the coagulation mechanism and accelerate the coagulation process. The type of serum preparation is suitable for emergency serum biochemical and pharmacokinetics tests. After collection, the mixture was reversed 5-8 times and stood upright for 20-30min before the supernatant was centrifuged and used.
4. The sodium citrate concentration required by the citrate erythrocyte sedimentation test tube with black cap is 3.2% (equivalent to 0.109mol/L), and the ratio of anticoagulant to blood is 1:4. Containing 3.8% sodium citrate 0.4mL, the blood was drawn to 2.0ml, which was a special test tube for erythrocyte sedimentation rate. The sample type was plasma, which was suitable for erythrocyte sedimentation. The blood was reversed and mixed 5-8 times immediately after the blood was drawn. It should be shaken again when it is used. The difference between it and the test tube for coagulation factors is that the concentration of anticoagulant is different from the proportion of blood and cannot be confused.
5. Sodium citrate coagulation test tube light blue cap Sodium citrate plays an anticoagulant role mainly by chelating with calcium ions in blood samples. The National Committee for Clinical Laboratory Standards recommends an anticoagulant concentration of 3.2% or 3.8% (equivalent to 0.109 or 0.129mol per liter), with an anticoagulant to blood ratio of 1:9. The vacuum tubes contained 0.2mL of 3.2% sodium citrate anticoagulant, and the blood was collected to 2.0ml. The sample preparation type was whole blood or plasma. After collection, the samples were immediately reversed and mixed 5-8 times, and the upper plasma was taken after centrifugation for use.
6. Heparin is added to the green head of the heparin anticoagulant tube. Heparin has a direct antithrombin effect and can prolong the coagulation time of the specimen. It is used in emergency and most biochemical tests, such as liver function, renal function, blood lipids, and blood glucose. It is suitable for erythrocyte fragility tests, blood gas analyses, hematocrit tests, erythrocyte sedimentation rates, and common biochemical tests. It is not suitable for hemagglutination tests. Excessive amounts of heparin cause aggregation of leukocytes and cannot be used for leukocyte counting. Because it can make the background of the blood stain pale blue, it is also not suitable for leukocyte classification. It can be used for hemorheological use, the sample type is plasma, and immediately after blood collection, it is reversed and mixed 5-8 times, and the upper plasma is taken for use.
7. The light green head of the plasma separation tube is added with heparin lithium anticoagulant in the inert separation rubber tube, which can achieve the purpose of rapid separation of plasma. It is the choice of electrolyte detection, and can also be used for routine plasma biochemical determination and ICU and other emergency plasma biochemical detection. It is used in emergency and most biochemical tests, such as liver function, renal function, blood lipids, and blood glucose. Plasma samples can be directly loaded on the machine and remain stable for 48 hours in refrigerated storage. It can be used for hemorheological use, the sample type is plasma, and immediately after blood collection, it is reversed and mixed 5-8 times, and the upper plasma is taken for use.
8. Potassium oxalate/sodium fluoride grey cap sodium fluoride is a kind of weak anticoagulant, usually with potassium oxalate or sodium ethylate combined use, the proportion of sodium fluoride 1 part, potassium oxalate 3 parts. "This mixture, 4mg, does not coagulate 1ml of blood for 23 days and inhibits glycogenolysis, is not useful for urease determination of urea, nor for alkaline phosphatase and amylase determination, and is recommended for blood glucose determination." It contains sodium fluoride or potassium oxalate or ethylenediaminetetraacetic acid disodium (EDTA-Na) spray, which can inhibit the activity of enolase in glucose metabolism. After blood is drawn, it is mixed reversely 5-8 times, and after centrifugation, the supernatant plasma is taken for use. It is a special tube for the rapid determination of blood glucose.
9. EDTA anticoagulant tube purple cap ethylenediamine tetraacetic acid (EDTA, molecular weight 292) and its salt is an amino polycarboxylic acid, suitable for general hematology test, is the first choice for blood routine, glycosylated hemoglobin, blood group test tube. It is not suitable for coagulation tests and platelet function tests. It is also not suitable for the determination of calcium, potassium, sodium, iron, alkaline phosphatase, creatine kinase, and leucine aminopeptidase. 100ml of the 2.7%EDTA-K2 solution was sprayed on the inner wall of the vacuum tube, blown dry at 45 ° C, and blood was collected to 2mI. Immediately after blood was drawn, the mixture was reversed and mixed 5-8 times before use. The sample type was whole blood, which should be mixed during clinical use.
