Important Note

*This test is orderable in Cerner as Hemoglobin A1c

This test subject to reflex testing. If Hemoglobin A1C shows a suspicious Hgb not previously identified or if HBA2 is >3.4%, which is suspicious of beta-thalassemia, a Hemoglobin/Thalassemia Evaluation will be performed (cpt: 83020/85660/83021).  You have the option to decline reflex testing if you believe it is not medically necessary. If we are not able to assay using the Hemoglobin A1C test methodology due to the presence of an abnormal hemoglobin in the patient sample, the test will be credited with the following reason:  "A1c unreportable.  Abnormal hemoglobin present.  Measurement of serum fructosamine may be helpful to monitor glycemic control."
