What is the diagnosis for Diamond Blackfan Anemia (DBA)?

It is usually diagnosed during the first year of life. Several tests can be used to tell if a person has DBA. One test a doctor can perform is called a bone marrow aspirate. This is a test in which a needle is inserted into a bone and a small amount of bone marrow fluid is taken out and studied under a microscope. Blood tests can also be done to see if there is a genetic basis for DBA or certain chemical abnormalities linked to DBA.
