Overview of Anemia
Diagnosis of Anemia
Blood tests Sometimes anemia is detected before people notice symptoms when routine blood tests are done. Low levels of hemoglobin or a low hematocrit (the percentage of red blood cells in the total blood volume) found in a blood sample confirm the anemia. Other tests, such as examining a blood sample under a microscope and, less often, examining a sample taken from the bone marrow, help determine the cause of the anemia.
