>> Features
- 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.
>> Purpose
- Plasma Chemistry Tests: Heparin prevents clotting by inhibiting thrombin
- Emergency & Point-of-Care Testing (POCT): STAT chemistry panels (fast results for critical care), or Glucose testing (if processed immediately, unlike gray-top NaF tubes).
- Hematology: Toxicology/drug level monitoring
- Flow cytometry (cell surface marker analysis).
