# Hemoglobinopathy Fractionation Cascade

> This test measures the types and amounts of hemoglobin, the protein in your red blood cells that carries oxygen. It helps show whether an inherited blood disorder is the cause of symptoms like fatigue or unexplained anemia. The results allow doctors to check for specific conditions like thalassemia or sickle cell disease. However, this test describes the physical properties of your hemoglobin and does not map your specific DNA or genetic code by itself.
