One-time vacuum blood collection tubes

Red blood collection tubes – normal/rapid serum tubes

Does not contain anticoagulants, the inner wall of the blood collection blood vessels is evenly coated with anti-wall agents, mainly used for blood biochemistry.

Sample type: Serum

Uses: bacteria, tumor, gonadal, immunoconventional, immune whole, rheumatic antibody, diabetic nephropathy detection, blood triathlon, ICA (insulin cell antibody), GAD (glutamate decarboxylase antibody), ABAP (osteoalkali phosphonase), prostaglandins (T-PSA-F-PSA), HBV-DNA, ferritin, cold set, procalcitonin PCT, mycoplasma antibody, gastrin, ANCA, blood cytomegalovirus antibody, human epididymal epididymal secreted protein, serum protein electrophoresis, RA five , TB-AD tuberculosis antibodies.

Green blood collection tubes – heparin anticoagulant tubes

Heparin is added in the blood collection vessels, heparin directly has the effect of antithrombin, can prolong the coagulation time of the specimen, excess heparin will cause the aggregation of white blood cells, can not be used for white blood cell count, because it can make the background light blue after staining the blood film, so it is not suitable for white blood cell classification.

Sample type: whole blood, plasma

Uses: red blood cell fragility test, blood gas analysis, hematocrit test, erythrocyte sedimentation rate and general energy biochemical determination.

Light green blood collection tubes – plasma separation tubes

Contains heparin lithium or heparin sodium and gel, heparin is a mucopolysaccharide containing a sulfate group, with a strong negative charge, has the effect of strengthening antithrombin 3 to inactivate serine protease, thereby preventing the formation of thrombin, and has a variety of anticoagulant effects such as preventing platelet aggregation, usually 15IU heparin anticoagulates 1ml of blood. Heparin tubes are generally used for emergency biochemical and blood rheology testing.

Sample type: plasma

Uses: TNT, environmental protection mycin, B27, blood ammonia, BNP (type B natriuretic peptide)

Dark blue blood collection tubes – trace element tubes

Contains heparin sodium, EDTA Na2, EDTA K2, coagulant (plastic tube, serum) and coagulant-free (glass tube, serum) additive. Heparin sodium should not be used when testing sodium ions in blood samples to avoid affecting the test results.

Uses: trace elements, toxicology and nutritional chemistry testing

Purple blood collection tube – EDTA anticoagulant tube

Contains EDTA anticoagulant, in blood routine detection, EDTA anticoagulant has less effect on blood cell agglutination and blood cell morphology than other anticoagulants, so EDTA salts (2K, 3K, 2Na) are usually used as anticoagulants. EDTA salts combine with calcium ions in the blood to form chelates, which prevent blood clotting.

Sample type: whole blood, plasma

Use:

2ml: CBC, reticulocytes, glycated hemoglobin (HBAIC), TC bloodgroup, BNP (beat)

5ml: pituitary, parathyroidine, renin, adrenal function, adrenal function, adrenal function ATCH + COR, cortisol (COR), blood group + D antigen (zygosy)

It is not suitable for coagulation test and platelet function test, nor is it suitable for the determination of calcium, potassium, sodium, iron, alkaline phosphatase, creatine kinase and leucine aminopeptidase and PCR test.

Golden blood collection tubes - inert separation of coagulant tubes

Contains inert separation gel and coagulant, and the tube wall is coated with coagulant to accelerate the coagulation of blood, avoid 37°C water bath, and shorten the test time. The separation glue has a good affinity with the PET tube and plays a role in isolation.

Specimen type: Serum

Use:

3ml: biochemical items, digoxin concentration, myocardial enzymes, amylase, thyroid function, thyroid function, free thyroid function, total thyroid hormone determination, thyroid antibody, thyroid receptor antibody

5ml: C-reactive protein (CRP immunity, both red and yellow), high-sensitivity C-reactive protein (hs-CRP)

Light blue blood collection blood vessels - sodium citrate blood collection blood vessels

Contains 3.2% or 3.8% sodium citrate (sodium citrate), please pay attention to the amount of blood collected to ensure the accuracy of the test results. Immediately after blood collection, mix upside down 5-8 times. The ratio of anticoagulants to blood is 1:9.

Specimen type: whole blood, plasma

Uses: for fibrinolytic systems (prothrombin time, thrombin time, activated partial thrombin time, fibrinogen).

Black blood collection blood collection tube-sodium citrate erythrocyte sedimentation rate test tube

Contains 3.2% (0.109mol/L)-3.8% sodium citrate (sodium citrate), its anticoagulant to blood volume ratio is 1:4, when the anticoagulant ratio is too high, blood is diluted, can accelerate erythrocyte sedimentation. Heparin anticoagulants can change the potential of red blood cells, so it is not suitable for testing the erythrocyte sedimentation rate.

Sample type: whole blood

Uses: ESR
