Classification and Application

1.Red blood collection vessel -- common / rapid serum tube
There is no anticoagulant, also known as biochemical tube. The inner wall of the blood collecting vessel is evenly coated with agents to prevent wall hanging. It is mainly used for blood biochemistry. It is divided into ordinary serum tube and rapid serum tube. The label will indicate whether there is coagulant or not, or use red and orange to distinguish the two. The function of coagulant is to accelerate blood coagulation. If you want to clot quickly, you can use the procoagulant tube.
Sample type: Serum
Uses: tumor, gonad, immune routine, immunization, rheumatoid antibody, diabetic nephropathy detection, blood three items, ICA (insulin cell antibody), GAD (glutamic acid decarboxylase antibody), ABAP (bone type alkaline phosphatase), prostaglandin (T-PSA-F-PSA), HBV-DNA, ferritin, condensation set, procalcitonin PCT, mycoplasma antibody, gastrin, ANCA, CMV antibody, human epididymal epithelial secretory protein, serum protein electrophoresis, RA, tb-ad, TB antibody.
2.Green blood collecting vessel heparin anticoagulant tube
Heparin is added to the blood collection vessel. Heparin directly has the effect of antithrombin, which can prolong the clotting time of the specimen. Excessive heparin will cause the aggregation of leukocytes, and can not be used for leukocyte count. Because it can make the background of blood stained light blue, it is not suitable for leukocyte classification.
Sample type: whole blood, plasma
Purpose: erythrocyte fragility test, blood gas analysis, hematocrit test, erythrocyte sedimentation rate and biochemical determination.
 
3.Light green blood collecting vessel plasma separating tube
Heparin containing lithium or heparin sodium and gel, heparin is a kind of mucopolysaccharide containing sulfuric acid group, with a strong negative charge, has enhanced the antithrombin 3 inactivation of serine protease, thereby preventing thrombin formation, and has prevented platelet aggregation and other anticoagulant effects. Under normal circumstances, 15IU heparin anticoagulant 1ml blood. Heparin tube is generally used for emergency biochemical and hemorheological tests.
Sample type: plasma
Uses: TNT, EPM, B27, blood ammonia, BNP (B-type natriuretic peptide)
4.Deep blue blood collection vessel trace element tube
It contains heparin sodium, EDTA Na2, EDTA K2, coagulant (plastic tube, serum) and additive without coagulant (glass tube, serum). Heparin sodium should not be used in the detection of sodium ion in blood samples, so as not to affect the detection results.
Purpose: trace element, toxicology and nutritional chemistry test
 
5.Purple blood collection -- EDTA anticoagulant
It contains EDTA anticoagulant. Compared with other anticoagulants, EDTA anticoagulant has less effect on hemagglutination and morphology of blood cells, so EDTA salt (2k, 3k, 2Na) is usually used as anticoagulant. EDTA salt can combine with calcium ion in blood to form chelate, so as to prevent blood coagulation.
Sample type: whole blood, plasma
Application:
2ml: blood routine, reticulocyte, HBAIC, TC, BNP
5ml: pituitary, parathyroid hormone, renin, adrenal function, adrenocortical function, atch + COR, cortisol (COR), blood group + D antigen (syncytial blood)
It is not suitable for coagulation test and platelet function test, nor for determination of calcium, potassium, sodium, iron, alkaline phosphatase, creatine kinase, leucine aminopeptidase and PCR test.
 
6.Golden yellow blood collecting vessel -- Inert separation and coagulation promoting tube
It contains inert separation gel and coagulant. The coagulant on the tube wall can accelerate the coagulation of blood, avoid 37 ℃ water bath and shorten the test time. The separation gel has good affinity with pet tube, and plays an isolation role.
Specimen type: Serum
Application:
3ml: biochemical items, digoxin concentration, myocardial enzyme, amylase, thyroid function, total thyroid function, free thyroid function, total thyroid hormone determination, thyroid antibody, thyroid receptor antibody
5ml: C-reactive protein (CRP), high sensitivity C-reactive protein (hs CRP)
 
7.Light blue blood collecting vessel sodium citrate blood collecting vessel
It contains 3.2% or 3.8% sodium citrate. When taking blood, please pay attention to take enough blood to ensure the accuracy of test results. After blood collection, please reverse immediately and mix well for 5-8 times. The ratio of anticoagulant to blood was 1:9
Type of specimen: whole blood, plasma
Purpose: for fibrinolysis system (prothrombin time, thrombin time, activated partial thromboplastin time, fibrinogen).
 
8.Black blood collection vessel -- sodium citrate ESR test tube
It contains 3.2% (0.109 mol / L) - 3.8% sodium citrate. The volume ratio of anticoagulant to blood is 1:4. When the anticoagulant ratio is too high, the blood will be diluted and the ESR will be accelerated. Heparin anticoagulant can change the potential of red blood cells, so it is not suitable for the detection of erythrocyte sedimentation rate.
Sample type: whole blood
Application: ESR
 
9.Gray blood collection vessel -- sodium oxalate / sodium fluoride blood glucose test tube
The additive in the tube is sodium fluoride + potassium oxalate / sodium fluoride + heparin sodium. Sodium fluoride is a weak anticoagulant, which has a good effect in preventing the degradation of blood glucose. 4mg of the mixture of sodium fluoride + potassium oxalate / sodium fluoride + heparin sodium can make 1ml blood not coagulate and inhibit the decomposition of sugar in 23 days. Please pay attention to slowly reverse and mix well when using it.
Purpose: blood glucose detection, can not be used for urea Urease method, also can not be used for alkaline phosphatase and amylase determination.
 
 

Storage Requirements

Store in a dry, well-ventilated and clean room with no corrosive gas and relative humidity above 80%
 

Precautions During Use

1.According to different test requirements, select the appropriate blood collection vessel. If you have any questions, please contact the staff of the laboratory at any time.
2.The sample number must be pasted on the blood collection vessel, which is consistent with the number on the inspection sheet. It should be pasted on the paper label of blood collection vessel, not on the glass to prevent falling off.
3. When taking blood, patients should be relaxed, warm environment, prevent venous contracture, tie tourniquet time should not be too long (now some scholars think that try not to use tourniquet), observe whether the blood collection is smooth, forbid to pat the arm, otherwise it may cause local blood concentration or activate the coagulation system.
4. The recommended order of blood collection is no anticoagulant tube (serum tube) → separation gel / accelerator tube → heparin / EDTA tube → coagulation vessel → blood sedimentation tube. The main reason is that the first tube often contains tissue fluid, which is easy to cause coagulation and is not suitable for hemagglutination test; Furthermore, to avoid the contamination of serum tube by anticoagulant.
5. After blood collection, the blood samples shall be rolled according to different test categories (biochemical, immune, routine, coagulation, ESR) with test sheets, and classified. All blood samples shall not be mixed together, so as to avoid confusion in operation.
6.The proportion of blood and anticoagulant must be accurate, and the blood volume should meet the requirements.
7 after blood collection, gently turn the test tube and mix 8-10 times, but do not vibrate violently. The sample should be placed vertically after blood collection.
