血红蛋白SC病同明有血红蛋白S和血红蛋白S的存在，RBC可能呈镰状，但不如血红蛋白SS那样常见。血红蛋白C导致靶细胞(红细胞)中心略带红色。视野中心可见一矩形红细胞(因血红蛋白C晶体存在)，也是血红蛋白C病的特征。
This patient has hemoglobin SC disease, with hemoglobin S and hemoglobin C both present. With SC disease, the RBC's may sickle, but not as commonly as with Hemoglobin SS disease. The hemoglobin C leads to the formation of "target" cells--RBC's that have a central reddish dot. In the center of the field is a rectangular RBC that is indicative of a hemoglobin C crystal, which is also characteristic for hemoglobin C disease.
