Lavender/Purple Stopper Vacuum Tubes for Blood Sample Centrifugation

Product Description

Blood sample tubes are tools for collecting, storing and processing blood, and are widely used in medical testing and clinical diagnosis. In order to ensure the accuracy and efficiency of blood testing, the type of blood collection tube and the choice of additives are crucial. The following will introduce the types of blood sample tubes and their specific uses in detail:

Red top blood collection tubes

Use: These blood collection tubes do not add any anticoagulants or additives, and are mainly used for serological tests, such as biochemical tests, immunological tests, etc.
Features: Red top blood collection tubes allow blood to be separated into serum after coagulation. Serum does not contain coagulation factors and is suitable for the detection of most blood proteins, hormones and electrolytes.

Green top blood collection tubes

Use: Green blood collection tubes containing heparin anticoagulants are mainly used for blood gas analysis, electrolyte testing, hematocrit and emergency biochemical testing.
Features: Heparin has an anticoagulant effect and can prolong the coagulation time of the specimen. It is suitable for tests that require whole blood or plasma samples.

Purple/pink top blood collection tubes

Use: Blood collection tubes containing EDTA anticoagulants are mainly used for blood cell counting, blood typing and blood pathology tests, such as blood routine tests and blood sugar tests.
Features: EDTA can prevent blood coagulation by chelating calcium ions, which is very important for blood cell counting and blood typing.

Blue top blood collection tube

Purpose: Mainly used for coagulation function tests, such as thrombin time, partial thromboplastin time and fibrinogen determination.
Features: 3.2% or 3.8% sodium citrate anticoagulant is added to the blood collection tube, which can remove calcium from the blood and thus play an anticoagulant role.

Yellow top blood collection tube

Purpose: Yellow top blood collection tube containing anticoagulant EDTA is mainly used for blood pathology detection, such as blood routine, blood sugar detection, etc.
Features: EDTA can prevent blood coagulation by chelating calcium ions, which is very important for blood cell counting and blood typing.

Black top blood collection tube

Purpose: Mainly used for erythrocyte sedimentation rate determination.
Features: Contains 3.2%-3.8% sodium citrate anticoagulant, and the volume ratio of anticoagulant to blood is 1:4, which helps to measure the erythrocyte sedimentation rate.

In summary, the choice of blood sample tubes has a significant impact on the accuracy of experimental results. Different types of blood collection tubes and additives determine the specific use and detection methods of blood samples. Correctly selecting the type of blood collection tube can not only improve experimental efficiency, but also ensure the accuracy and reliability of test results. Laboratory staff should fully understand the characteristics and applicable scenarios of different blood collection tubes in order to better conduct experimental design and data interpretation.
