Which type of blood collection tube is used for HbA1c testing?

Glycated hemoglobin (HbA1c) testing typically uses a red-top blood collection tube—the same type commonly used for complete blood count (CBC) tests. However, the specific tube type may vary depending on the healthcare facility where you receive care. We recommend visiting a reputable, comprehensive general hospital in your local area for this test, as such hospitals generally have well-equipped laboratories and adhere to standardized procedures. Prior to the blood draw, ensure thorough cleansing of the skin at the puncture site, and proper disinfection must be performed before venipuncture. Afterward, pay attention to post-procedure care of the puncture site.
