Mixing Study: Specimen Requirements

The specimen drawn for a mixing study must meet the following conditions for accurate testing:

  • A properly filled 3.2% sodium citrate tube must be collected.
  • Proper centrifugation to create platelet-poor plasma for analysis must occur; the presence of platelet phospholipids can interfere with the mixing study if an anti-phospholipid antibody is present.
  • Testing must be performed within 4 hours of collection.
