Blood tests are currently one of the most common testing items in clinical medical institutions, and the corresponding high-quality blood samples have become the key before testing. Disposable vacuum blood collection tubes are widely used in the collection of blood samples in clinical medical institutions because of their simple operation, safety, efficiency, accuracy and reliability. However, there are many kinds of disposable vacuum blood collection tubes (color labels of tube caps), each of which has its specific use.
1. Purple cap: EDTA anticoagulant tube ( routine blood test tube)
The purple cap blood collection tube containing EDTA-K2, EDTA-K3 and other anticoagulants is more common, which we call the routine blood test tube, mainly used for routine blood tests, etc.
2. Pipe without additives
Additive-free dried tubes, which use the principle of natural coagulation of blood to allow coagulation, are mainly used for general serum biochemical tests.
Three, Promoting Coagulation Tube
添加 of a coagulant to the blood tube, which can cause the collected blood to coagulate within 5 minutes, suitable for emergency serum series tests.
IV. Separation Gel/Coagulant Tube
The collection tubes contain inert separation gel and coagulant, mainly used for clinical biochemical, clinical immunological items detection, etc.
5. Common green cap: Heparin anticoagulant tube
The collection tubes contain heparin sodium, heparin lithium, and other heparin anticoagulants, which can directly inhibit the activity of thrombin, prevent blood coagulation, and are often used in plasma biochemical experiments, hemorheological experiments, etc.
Six, Blue Head: Blood Coagulation Tube
For the determination of coagulation factors, tubes with quantitative liquid citrate/citric acid anticoagulant buffer are added to the tubes, which are used for the examination of coagulation mechanism items such as PT, APTT, etc.
Seven, black skull: blood沉 tube
It is dedicated to the determination of erythrocyte sedimentation rate, i.e. the sedimentation test. It contains a specific ratio of citrate/citric acid anticoagulant.
8. Light green head: plasma separation tube
Blood collection tubes containing anticoagulants such as heparin lithium or sodium heparin and inert separation gel can achieve the purpose of rapid plasma separation, which is the best choice for electrolyte testing.
Nine, gray head: blood sugar tube
Special tubes for measuring blood sugar, with fluorides added as inhibitors to keep the blood sample in its original condition.
At the same time, the disposable vacuum blood collection tube, with its aseptic design, vacuum seal, single-use, and convenient sample processing features, also ensures the purity and asepsis of the collected blood samples, avoiding the risk of cross-infection.
In general, there are many types of disposable vacuum tubes, each with its specific use and application. Medical staff should choose the corresponding type of tube according to the specific condition of the patient and the needs of the collection test when using them, so as to ensure the quality of the blood sample collected and the accuracy of the test results.
