These expired Green Blood Collection Tubes are for use in training with training arms only. 100 per pack. -
These are PST "Plasma Separator Tube"
The interior of the tube wall is coated with lithium heparin, ammonium heparin or sodium heparin. The anticoagulant heparin activates antithrombins, thus blocking the coagulation cascade and producing a whole blood / plasma sample instead of clotted blood plus serum. Plasma separator tubes (PST) are tubes with lithium heparin and gel contain a barrier gel in the tube. The specific gravity of this material lies between that of the blood cells and plasma. During centrifugation the gel barrier moves upwards providing a stable barrier separating the plasma from cells. Plasma may be aspirated directly from the collection tube, eliminating the need for manual transfer to another container. This barrier allows for the stability of certain parameters in the primary tube under the recommended storage conditions for up to 48 hours. Check the heparin additive before use. Do not use heparin plasma tubes for TDM measurements, lithium heparin for lithium determinations, sodium heparin for sodium determinations, ammonium heparin for ammonia determinations or any type of heparin for blood banking procedures.
Clinical Chemistry -The clinical chemistry laboratory performs a wide variety of analytic procedures, both specialized and routine. These include tests for the evaluation of endocrine and metabolic disorders, therapeutic drug monitoring and toxicology, protein electrophoresis, lipid panels, as well as those tests commonly called routine such as hepatic function tests, electrolytes and markers of cardiac damage.
For plasma determinations in the chemistry department. Many institutions use red stoppered tubes for routine chemistry tests and green stoppered tubes for STAT chemistry tests.
