Ordering Recommendations

HbA1c reflects the average blood glucose level during the preceding 2 to 3 months and is suitable to monitor long-term blood glucose control in individuals with diabetes mellitus. HbA1c also predicts the development of diabetic complications.

Components

Estimated Average Glucose (eAG) provided with all Hemoglobin A1c Test Results

Specimen Type

Whole Blood

Collection Method

Standard venipuncture.

Collect

1 Lavender tube (EDTA)

Alternate Specimen Container

None

Minimum Volume

1 mL

Optimum Volume

5 mL

Patient Preparation

None

Specimen Preparation

Do not centrifuge; Refrigerate until testing.

Stability (from collection to initiation)

2-8°C up to 7 days

Unacceptable Conditions

Total clotted samples will be rejected. However, partially clotted samples may be analyzed without adverse affects on test result per manufacturer.

CPT Codes
