1. Red blood collection tube: used to collect ordinary serum, the blood collection tube does not contain additives, and is used for routine serum and biochemical related tests.

2. Orange-red blood collection tube: There is a coagulant in the orange-red cap blood collection tube, which can activate fibrinase and turn soluble fibrin into insoluble fibrin polymers, thereby forming a stable fibrin clot. Suitable for emergency serum tests.

3. Green blood collection tube: heparin is added in the blood collection tube. Heparin has the effect of antithrombin, which can prolong the clotting time of the specimen. It is mainly suitable for routine biochemical and emergency plasma testing, such as liver and kidney function, blood lipids, blood sugar, etc.
