Anemia is a blood disorder marked by a decreased amount of red blood cells (RBCs). People with anemia have insufficient hemoglobin, a protein in red blood cells that carries oxygen through the body. Anemia is the most common blood disorder in Americans, and it can have far-reaching symptoms or none at all. Some of the most common symptoms include fatigue, shortness of breath, and headaches. There are multiple types of anemia with diverse potential causes. Anemia is usually related to a failure to generate enough normal red blood cells, increased destruction of red blood cells, or blood loss. Anemia testing is essential to diagnosing anemia and identifying its underlying cause. Simple blood tests can both determine if you have anemia and what the cause may be, which helps determine treatment options. By Jennifer Acosta ScottMedically Reviewed by Pat F. Bass III, MD, MPH Reviewed: January 9, 2014 Medically Reviewed When your doctor suspects that you have anemia, a condition caused by the blood’s inability to deliver enough oxygen to the body, the first step is usually a diagnostic test. Blood tests can tell your physician whether you are truly anemic, said Raymond Liu, MD, a hematologist with Kaiser Permanente Hospital in San Francisco, along with what is causing the anemia. Anemia Test No. 1: Complete Blood Count (CBC)If you’re experiencing symptoms of anemia, the most common diagnostic test is a complete blood count, known as a CBC. A CBC involves taking a small blood sample and analyzing its components, including the red blood cells, white blood cells, and platelets. “It tests at all the elements of the blood, but mainly we’re looking at the red blood cells because a low red blood cell count can mean anemia,” Dr. Liu said. The CBC also measures levels of hematocrit (the percentage of red blood cells found in whole blood) and hemoglobin (an oxygen-carrying protein in the blood). Low levels of either hematocrit or hemoglobin can indicate an anemic condition. The complete blood count is the main test used to make a general diagnosis of anemia, Liu said, after which other diagnostic tests can be ordered as needed. “After we’ve determined there is anemia, we can determine the cause,” explained Liu. Anemia Test No. 2: Reticulocyte CountOne such diagnostic test is a reticulocyte count, which measures the number of immature red cells in the blood. These cells are produced by bone marrow, and a high reticulocyte count could mean that your symptoms of anemia are due to blood loss, either through hemorrhaging, heavy menstrual periods, or sources of blood loss. “If your bone marrow is responding very well and producing lots of red blood cells, then the reticulocyte count should be high because the red blood cell factory is working overtime to make up for those lost red blood cells,” said Liu. A low reticulocyte count, on the other hand, means that your bone marrow is not producing enough red blood cells. This is most commonly caused by a nutritional deficiency. “If you don’t have enough iron or vitamin B12, you can’t make red blood cells,” Liu explained. Folate deficiency can also be a cause of a low reticulocyte count, though it’s less common in the Western world because many foods, such as bread, are fortified with folate. People who have cancer or are undergoing radiation therapy may also experience low reticulocyte counts, as well as those whose kidney function is impaired. Once the cause of the low reticulocyte count has been determined, your doctor can decide how to treat your anemia, Liu said. If a low reticulocyte count is caused by nutritional gaps, you can take supplements of appropriate vitamins, such as iron, B12, or folate. If your reticulocyte production has been suppressed due to kidney problems, a physician may treat you with injections of erythropoietin, a hormone produced by the kidneys that tells the bone marrow to produce more red blood cells. Anemia Test No. 3: Blood SmearAnother test that helps search for anemia causes is a blood smear. This test, which is performed by spreading a drop of blood on a slide and staining it with a special dye, can detect irregularities in red blood cells, white blood cells, and platelets. Abnormal red blood cells can tell your doctor more about your anemia. For example, unusually large red blood cells can indicate anemia caused by a vitamin deficiency, while crescent-shaped red blood cells can mean you have sickle-cell anemia, an inherited disease. The treatments that your physician prescribes after a blood smear will depend on the test results. If your blood smear reveals vitamin deficiencies, changes in diet or taking vitamin supplements may be the only treatment you need. There is no cure for sickle-cell anemia, but patients are often told to stay hydrated and in good health because being in less-than-ideal physical condition can cause painful episodes, known as “sickle cell crises” that occur when misshapen red blood cells form clumps in the bloodstream. “Anything that stresses the body out can lead to crisis,” Liu says. People with moderate to severe sickle-cell anemia may also be prescribed a drug called hydroxyurea to prevent episodes of pain. Anemia Test No. 4: Iron PanelIf your doctor suspects that your anemia is due to an iron deficiency, she may order an iron panel, a blood test that measures the level of iron in your blood. This test is often used when your doctor believes that your iron deficiency is caused by blood loss, such as bleeding in the gastrointestinal tract. “If we suspect there is blood loss related to an iron deficiency, we definitely do an iron panel,” Liu said. “If someone’s anemic, it can help us estimate how long their recovery time will be.” Treatment for iron deficiency involves taking iron supplements, usually in pill form. Those who cannot tolerate oral iron supplements can also take it intravenously or by an injection into the muscle. If you suspect you have symptoms of anemia, talk to your doctor. Once simple blood tests determine the cause of your anemia, you and your doctor can work together to get you back to optimal health.
