Which type of tube contains lithium heparin and a plasma separator gel?
Light green-top tube
Light green-top tube (lithium heparin) This tube contains lithium heparin and gel separator used for the collection of heparinized plasma for routine chemistry tests. NOTE: After the tube has been filled with blood, immediately invert the tube 8-10 times to mix and ensure adequate anticoagulation of the specimen.
What is a lithium heparin tube?
VACUETTE® LH lithium heparin tubes are coated with lithium heparin on the inside. The anticoagulant heparin activates antithrombin, which blocks the clotting cascade and thus produces a whole blood/plasma sample. Selected tubes are also available with a transparent label.
What does lithium heparin do in a blood tube?
VACUETTE® LH lithium heparin tubes are coated with lithium heparin on the inside. The anticoagulant heparin activates antithrombin, which blocks the clotting cascade and thus produces a whole blood/plasma sample.
Does lithium heparin give plasma or serum?
Lithium/Sodium Heparin (Green) Similar in use to serum clot activator tubes, but suitable for tests in plasma rather than serum. Like the serum tubes, heparin tubes can also come with a separating gel. Heparin acts by inhibiting thrombin formation.
Is lithium heparin an anticoagulant?
Lithium heparin, which is used exclusively in the laboratory as an in vitro anticoagulant, is prepared from sodium heparin by cation-exchange chromatography.
What color is lithium heparin tube?
Green-top tube: Contains sodium heparin or lithium heparin.
What goes in a lithium heparin tube?
Heparin VACUETTE® heparin tubes are coated on the inside wall with spray-dried lithium, ammonium or sodium heparin and are used to determine analytes in clinical chemistry. The additive acts as an anticoagulant, and blocks the clotting cascade.
What is heparin plasma?
Heparin plasma is an attractive alternative to the established EDTA samples which can be used for BNP determination. This flexibility allows the simultaneous determination of CK, CK-MB, cTnI and BNP on a single heparin specimen, which facilitates blood collection for clinicians and nursing staff in an emergency unit.
What tube is used for plasma?
Use: EDTA whole blood or plasma. Send plasma in a plastic transport tube labeled “Plasma, EDTA.” Send whole blood in a lavender-top tube. Gray-top tube: Contains sodium fluoride (a preservative) and potassium oxalate (an anticoagulant).
Is Lithium heparin an anticoagulant?
How does lithium heparin work as an anticoagulant?
Heparin induces the inhibition of thrombin and Factor X to prevent clotting or activation of thrombin, which in turn prevents the formation of fibrin from fibrinogen. Lithium heparin is recommended because it is the least likely to interfere with the results when performing tests for other ions, like sodium.
