  • Severe hemolysis,
  • Bilirubinemia
  • Lipemia
  • Improper sample preparation or handling may affect assay results or sample stability, especially after freezing.
  • Release of platelet factor 4 resulting from inadequate removal of platelets or platelet activation of the sample may reduce the measured heparin concentration.

Specimen

  
Sodium citrate (Na Cit) plasma
  
  
1.0 mL
  

Immediatley following collection, mix sample thoroughly by gentle inverting 8 - 10 times, to prevent clotting

  
  1. Centrifuge for 10 minutes and carefully remove 2/3 of the plasma using a plastic transfer pipette, being careful not to disturb the cells.
  2. Deliver to a plastic transport tube, cap, and recentifuge for 10 minutes.
  3. Use a second plastic pipette to remove plasma, staying clear of the platelets at the bottom of the tube.
  4. Transfer the plasma into a Screw-cap polypropylene frozen transport vial/tube - 4mL (LabCorp), labelled as Na cit plasma.
  5. Freeze immediately
  
Frozen (preferred)
