👉 In medical terminology, a person is considered hemoglobinophilic if their red blood cells contain hemoglobin, which is an iron pigment found in red blood cells. Hemoglobin is responsible for carrying oxygen from the lungs to the rest of the body and delivering it back when needed. When someone has hemoglobinophilic characteristics, they are more likely to have a higher chance of developing conditions such as sickle cell disease or sickle-cell anemia because their red blood cells contain too little hemoglobin.
