What is whole blood collection tube?

Introduction of blood collection tube

Red tube cap collection vessel does not contain any additives, which is suitable for routine biochemical serum test and has no effect on test results. Disadvantages: If the centrifugation is not in place or the incubation time is not enough, fibrin is easy to form, which is easy to block the pinhole of the equipment. The orange tube cap collection vessel is added with coagulant, which can activate fibrinase and promote the soluble fibrin to form stable fibrin clots. The blood collected can be quickly centrifuged. It is generally suitable for some emergency experiments of **. Purple tube cap collection vessel contains EDTA-K2 anticoagulant, which is generally made by spray, so that the anticoagulant is evenly distributed on the wall of the tube. The specimen is prepared as whole blood, which is generally suitable for routine hematological testing. Heparin has the effect of antithrombin directly, can prolong specimen of blood coagulation time, generally for conventional biochemical detection and emergency plasma, has certain influence to some special biochemical projects, not suitable for blood clotting and routine blood test tube yellow hat vascular blood tube with inert separation gel, specimens after centrifugal separation gel * * in the blood serum and the blood completely separate, Long storage time, suitable for emergency serum biochemical detection black tube cap collection is generally used for coagulation mechanism detection, sodium citrate has little toxicity, also suitable for blood preservation vacuum collection esR tube characteristics and operation steps transparent tube.
