The expected RBC count in babies, children, and adolescents can vary significantly based on their age. At higher altitudes, less oxygen is available thus the need for your body to increase the number of RBCs that can deliver the required amount of oxygen. The number of RBCs can also be affected by elevation in the area where testing is conducted. Males typically have a higher number of RBCs than females. In general, reference ranges for adults typically fall between 4 and 6 million cells per microliter of blood. The normal range for red blood cells depends on factors like age and sex and can vary slightly among different laboratories due to the equipment used in different laboratories. RBC count is written as a number value in cells per microliter (number of RBCs x106/µL). Interpreting red blood cell test results: To monitor a long-term health problem that may change your blood count results, such as chronic kidney disease When you are receiving treatment that can affect your blood cell counts, such as chemotherapy If you are having other symptoms of blood cell changes, such as fever, infection, or weakness If you are having symptoms of anemia, such as fatigue, headache, loss of appetite, or problems concentrating ![]() Your health care provider may order this test: RBC count is usually tested as part of a complete blood count, which is a common lab test that can be used to detect or monitor many different health conditions. A high red blood cell count or high hemoglobin or hematocrit levels could point to a medical condition such as blood cancer or heart disease. A red blood cell count that's higher than usual is known as erythrocytosis. These symptoms may be due to the anemia itself or the cause of anemia. People with anemia might feel weak or tired. They include low levels of certain vitamins or iron, blood loss, or another medical condition. Lower than usual measures in these three areas are a sign of anemia. The results of these three markers are related because they each measure a feature of red blood cells. Red blood cell count, hemoglobin and hematocrit: You may also need this test if you have symptoms of a low or high red blood cell count. You may get this test as part of a complete blood count, which is often included in a routine checkup. The RBC measurement is used to help diagnose red blood cell disorders, such as anemia, a condition in which your body does not make enough healthy red blood cells. What is the red blood cell (RBC) test used for?Ī red blood cell (RBC) count is almost always part of a complete blood count, a group of tests that measure many different parts and features of your blood. ![]() So the test may allow you to get treatment even before you have symptoms. An RBC count that is higher or lower than normal is often the first sign of an illness. Your cells need oxygen to grow, reproduce, and stay healthy. Red blood cells carry oxygen from your lungs to every cell in your body. This test is almost always done as part of a complete blood count ( CBC) that also measures other types of blood cells. Red blood cell count is a blood test that measures the number of erythrocytes circulating in your blood. hematocrit: percentage of red blood cells in your bloodĪbnormal levels of red blood cells, hemoglobin, or hematocrit may be a sign of anemia, heart disease, or too little iron in your body. If your RBC count results are abnormal, additional tests are usually done to diagnose the cause of the high or low level of red blood cells.Ī CBC measures two other components of your red blood cells: Elevated RBC counts are seen in other conditions where there is low oxygen levels, certain drugs, kidney disease, or bone marrow overproduction. These cells are also known as erythrocytes.Īnemia is a condition that results from a decrease in the number of RBCs. They also carry carbon dioxide back to the lungs so it can be exhaled. Red blood cells (RBC) are made in the bone marrow and contain hemoglobin, a protein that carries oxygen to the tissues in the body. ![]() Red blood cells carry oxygen from the lungs to the rest of the body.
