|Green head tube|
Tube containing lithium heparin and liver  is a polysaccharides containing sulfate groups stick with a strong negative charge, can strengthen antithrombin III inactivated the role of serine protease, to prevent thrombin formation, and inhibits platelet aggregation, and other anticoagulant effect. Heparin tube is generally used for the detection of biochemical and blood rheology, and it is the best choice for the detection of electrolytes. Because heparin can cause aggregation of white blood cells, it can not be used for white blood cell count and classification.
|Red head tube|
Pipe wall are evenly coated to prevent the hanging wall of the silica, while adding a coagulant, coagulant to protease activated fiber, soluble fibrin into soluble fibrin monomer, thus forming a stable fibrin clot. Generally used for hepatitis B virus, thyroid function, drug testing, HIV testing, tumor markers, such as serum immune detection.
|Purple head tube|
Tubes containing ethylenediaminetetraacetic acid and its salt (EDTA), it is a multi amino carboxylic acid can effectively chelate blood calcium chelating will remove calcium from the reaction, and prevent and termination of endogenous or exogenous coagulation process, thereby preventing blood coagulation, compared with other anticoagulants, comparison, the of blood cell agglutination and blood cell morphology was less affected, so commonly used (2k, 3k, 2Na) salt of EDTA as an anticoagulant. Used for blood cell count and classification, such as general hematology examination, can not be used for blood coagulation, trace elements and PCR examination.
|Blue head tube|
Tubes containing sodium citrate, sodium citrate by in blood calcium chelation and anticoagulant effect, recommended by national clinical laboratory Committee for Standardization (NCCLS) 3.2% and 3.8%, anticoagulants and blood ratio 1:9, mainly for fibrinolytic system (prothrombin time, thrombin time, activation partial thromboplastin time, fibrin original) detection. Please note that the foot blood blood recovery, prevent the accuracy of the examination result in the death chamber. After blood collection, please immediately reverse mixing 5-8 times.
Tubes containing sodium citrate, sodium citrate concentration was 3.2% (0.109mol/L) and 3.8%, the anticoagulant and the blood volume ratio of 1:4, general due to the erythrocyte sedimentation rate, when the anticoagulant ratio is too high, the blood was diluted, the erythrocyte sedimentation rate (ESR).
