The Hemoglobin A1C (HbA1c) test typically uses a lavender-top tube (also known as a purple-top tube). This tube contains EDTA (ethylenediaminetetraacetic acid), which is an anticoagulant that prevents blood clotting and preserves the sample for accurate A1C measurement.

  • Tube Color: Lavender/Purple
  • Anticoagulant: EDTA

Always confirm with your lab or healthcare provider, as specific requirements may vary.
