A peripheral smear, which is also called a blood smear, is an essential diagnostic test for many conditions. Diamond-Blackfan anemia is one of them. A trained technician will spread a drop of blood in a thin layer onto a glass slide during a peripheral smear. Once this is done, they will treat the slide with a special stain. In other words, they count the different circulating blood cells. At this point, they will examine and evaluate the blood cells on the slide and check for any abnormalities. Results are available to the patient within one or two days.
