The purpose of the Heparin Tube is to extract plasma specimen, which is needed not only for emergency biochemistry tests, but also for blood rheology studies. Spray-dried lithium heparin and sodium heparin coat the inside wall of the tube. These additives are anti-coagulants that activate anti-thrombins, so stopping the blood specimen's coagulation cascade. Lithium Heparin Tubes with a separator gel are also available. The goal is to get a high-quality plasma specimen for a quick emergency biochemistry test.
Available in lithium heparin and sodium heparin.
The anticoagulant heparin activates antithrombin, which blocks the clotting cascade and thus produces a whole blood/plasma sample.
Lithium heparin has no interference with all ion detection during testing, including sodium ion.
The separation gel separates the plasma from the blood cells during centrifugation, preventing contamination of the plasma.
Immediately after draw, gently invert the tube 8-10 times in order to activate adequate anticoagulant.
Centrifugation: 1800-2200g for 8-15 minutes at 18-25° C.

EDTA effectively chelate calcium ions in blood samples, chelate calcium or react calcium Removal will block and terminate the endogenous or exogenous coagulation process, thereby preventing the blood specimen from clotting. Heparin is a highly charged biological molecule -polymeric glucosaminoglycan. It is a well known inhibitor of PCR and preferably should be avoided if collecting blood for PCR analysis.
