The lithium heparin tube is used in blood extraction and anticoagulation. It has green colored cap.
It is coated with lithium heparin or sodium heparin. The anticoagulant heparin activates antithrombin, blocking the clotting cascade and generating a plasma / blood for samples instead of a clotted blood with serum. The tube guarantees that, through its special mechanism, most of the plasma indicators can be repeated in 6 hours, especially for the most sensible tests like AST, ALT, TBIL, DBIL and GGT.
