Hemoglobine electrophoresis and dosage

Which test do we use?

Capilllary electrophoresis with the Minicap Flex Piercing (SEBIA)

If abnormal hemoglobin is detected a hemoglobin electrophoresis on agarose gel in a acidic medium will be performed as well. A sickling test will be performed if necessary.
