Hemoglobin A1c (HbA1c) with Electrophoresis

What Is HbA1c Electrophoresis Used For?

HbA1c electrophoresis provides a detailed breakdown of hemoglobin types, which can be useful for diagnosing conditions like thalassemia or sickle cell disease. It complements standard HbA1c testing by offering additional insights into hemoglobin composition, though it’s less commonly used than routine HbA1c alone.

How Is This Test Performed?

A small blood sample is taken, usually from your arm. The sample is then processed and run through an electrophoresis machine, which separates hemoglobin variants based on their electrical charge. The results are analyzed to identify specific hemoglobin types.

Why Might Your Doctor Order This Test?

Your doctor may order HbA1c electrophoresis if they suspect an inherited blood disorder (like thalassemia or sickle cell trait) or if you have unusual hemoglobin patterns on routine HbA1c testing. It helps confirm or rule out certain genetic blood conditions that affect how hemoglobin behaves in the bloodstream.

What Does the Test Result Mean?

The results show the proportion of different hemoglobin types, including glycated hemoglobin. While standard HbA1c measures overall sugar binding, electrophoresis can reveal if specific hemoglobin variants (e.g., HbA, HbF, or abnormal variants) are present, which may influence diagnosis or treatment planning.
