RBC details

Description

Red blood cell count (RBC) measures the actual number of oxygen-carrying red blood cells in a given volume of your blood, one of the core values in a complete blood count (CBC). A low RBC count generally indicates anemia, which can stem from blood loss, nutritional deficiencies (iron, B12, folate), chronic disease, or bone marrow problems; a high RBC count (polycythemia) can result from dehydration, chronic low oxygen levels, or, less commonly, a bone marrow disorder that overproduces red blood cells. It's typically interpreted together with hemoglobin, hematocrit, and other red blood cell indices.
