what is a hemoglobin test used for
A hemoglobin electrophoresis test is a blood test used to measure and identify the different types of hemoglobin in your bloodstream. Hemoglobin is the protein inside red blood cells that is responsible for transporting oxygen throughout your circulatory system to your tissues and organs. If your hemoglobin is of a healthy, ânormalâ type, it will transport and release oxygen with maximum efficiency.
