Additive: Lithium or Sodium Heparin 

Heparin is a natural anticoagulant which presents in any  healthy body. Heparin is used to take the plasma and in  chemical researches. 

Plasma is freed from the cells by the centrifugation. Clotting  of blood is prevented by the addition of an anticoagulant  directly after the taking of blood. 

For this purpose, the lithium or sodium heparin is added in  this tube. 

Advantages in comparison with serum: 

The bigger volume of material in the same volume of blood.  The results are independent on the condition of the  coagulation system. The results are closer to in vivo. 

Lower risk of hemolysis and thrombocytosis. 

Specimen: heparin plasma. 

The powder heparin is applied to the inner wall of the tube. 

The tubes contain a reagent at 12 - 30 IU of heparin per 1 ml  of blood. 

Immediately after taking the blood into the tube with  heparin it must be carefully mixed at least 8-10 time. 

Conditions of centrifugation: 1300 g for 10 minutes. 

Centrifugation should be made right after the drawing the  blood into the tubes.
