Blood Collection Tubes
Most blood collection tubes contain an additive that either accelerates clotting of the blood (clot activator) or prevents the blood from clotting (anticoagulant). A tube that contains a clot activator will produce a serum sample when the blood is separated by centrifugation and a tube that contains an anticoagulant will produce a plasma sample after centrifugation. Some tests require the use of serum, some require plasma, and other tests require anticoagulated whole blood.
The most commonly used blood collection tubes.Tube cap color Additive Function of Additive Common laboratory tests.
Light-blue
3.2% Sodium citrate Prevents blood from clotting by binding calcium Coagulation
Red or gold (mottled or “tiger” top used with some tubes)
Serum tube with or without clot activator or gel Clot activator promotes blood clotting with glass or silica particles. Gel separates serum from cells. Chemistry, serology, immunology.
Green
Sodium or lithium heparin with or without gel Prevents clotting by inhibiting thrombin and thromboplastin Stat and routine chemistry.
Lavender or pink
Potassium EDTA Prevents clotting by binding calcium Hematology and blood bank.
Gray
Sodium fluoride, and sodium or potassium oxalate Fluoride inhibits glycolysis, and oxalate prevents clotting by precipitating calcium. Glucose (especially when testing will be delayed), blood alcohol, lactic acid.


Clot Activator Tube
It is used in the fast blood sample collection for biochemistry and immunology in medical inspection. The influence by clot
activator is different from other chemical pre-coagulant method.
The Clot Activator shall be sprayed in the inner tube wall without any help of heating equipment(such as Water Temperature
Thermostat), and it adopts purely physical method to make the blood clot as fast as possible. Centrifuged in standing position for
15-30 minutes after blood collection, you can obtain the ideal and high-quality serum.
