A red blood cell count is a blood test that your doctor uses to find out how many red blood cells (RBCs) you have in your blood. It is also called an erythrocyte count. The test is important because RBCs contain hemoglobin, which carries oxygen to your bodyâs tissues.
Red blood is red because the color of oxyhemoglobin is red because there is iron in oxyhemoglobin, causing that blood red color. Red blood cells are red because the iron in the heme group of the four hemoglobin proteins react with oxygen (think what color rust is) to produce a red color.ed blood cells are red because the iron in the heme group of the four hemoglobin proteins react with oxygen (think what color rust is) to produce a red color.
