Serum tube is coated with silicon and micronized silica particles to rapidly activate the coagulation process by gently conducting mixing 8 to 10 times for serum measurement in biochemistry. Specially developed components on the wall make serum tubes reduce adherence of red blood cells to tube wall. Samples processed in these tubes may also be used for routine blood screening, immunohematology, and diagnostic testing of serum for infectious disease.

Serum with Gel contains a barrier polymer in the base of the tube and this material causes it to move upward to serum-clot interface forming a stable separation barrier during centrifugation. Serum may be aspired directly from the collection tube eliminating the need for manual transfer to another container. In the primary tube and under recommended laboratory conditions, certain parameters remain stable for up to 48 hours.

Coagulation tubes are used for examination of coagulation parameters. Coagulation tubes contain a buffered sodium citrate solution.It is available with a citrate concentration of 0.109 mol/l (3.2%) or 0.129 mol/l (3.8%). The choice of the concentration depends on the policy of the laboratories. The mixing ratio is 1part citrate solution to 9 parts blood.

EDTA Tubes are coated with K2-EDTA or K3-EDTA for blocking coagulation cascade by binding calcium ions in the blood sample. EDTA tubes must be inverted 8-10 times to assure complete mixing with blood for correct coagulation value. EDTA Tubes are used for direct sampling analysis since erythrocytes and leucocytes are stable for 24 hours with EDTA while thrombocytes are stable for 6-8 hours. Blood smearing should be done within 3 hours after blood collection. EDTA tubes are for the examination of whole blood in hematology.

Plasma tubes are coated with lithium heparin or sodium heparin to inhibit clotting. Heparin activates antithrombin, thus blocking the coagulation cascade and producing a whole blood/plasma sample instead of clotted blood and serum. Lithium determination should not be performed in lithium heparin tubes. Samples collected in these tubes are used for plasma determinations in chemistry.

Plasma tubes with gel contain spray-coated lithium heparin and a polymer gel in the bottom for plasma separation. The specific gravity of this material can make the barrier gel move upward to the plasma-clot interface during centrifugation and it forms a stable barrier separating the plasma from cells. Samples processed in these tubes are used for plasma determinations in chemistry. Those tubes provide the convenience of gel separation with the added advantage of improved turnaround time.
