Preferred Specimen(s)

Whole blood from a full EDTA (lavender-top) tube

Alternative Specimen(s)

Whole blood from a full EDTA (tan-top) tube

Minimum Volume

Microtainer 0.5 mL • 1 mL whole blood EDTA tube

Collection Instructions

Maintain specimen at room temperature. Do not refrigerate. If multiple draw, collect EDTA (lavender-top) tube last. Traumatic draw can introduce thromboplastin and trap WBC and platelets. Refrigeration can precipitate fibrin and trap WBC and platelets.

Note: If drawn with lead testing, EDTA (tan-top) is required.

Transport Container

EDTA (lavender-top) tube

Transport Temperature

Room temperature

Specimen Stability

  • Room temperature: 48 hours
  • Refrigerated: 48 hours (may cause platelet clumping)
  • Frozen: Unacceptable

Reject Criteria

Gross hemolysis • Clotted • Received frozen
