The Hemoglobin A1C (HbA1c) test typically uses a lavender-top tube (EDTA tube) for blood collection. This tube contains the anticoagulant ethylenediaminetetraacetic acid (EDTA), which prevents blood clotting and ensures accurate measurement of HbA1c levels.
- Lavender-top tube: Preferred for HbA1c testing due to its anticoagulant properties.
- Other tubes: In some cases, a green-top tube (heparin tube) may also be used, but the lavender-top tube is the standard.
Always confirm with your healthcare provider or lab for specific requirements.
