Anemia Research

The NHLBI leads and supports research on anemia, a condition that develops when your blood has a lower-than-normal amount of red blood cells or hemoglobin. Our research has helped scientists and doctors better understand the causes of anemia, and we have led and supported projects to discover exciting new treatments for this condition. We continue to fund studies to improve the survival and quality of life of people who have anemia. Research on anemia is part of NHLBI’s broader commitment to advancing scientific discovery for blood disorders and blood safety.

NHLBI research that really made a difference

NHLBI research that really made a difference
  • ​​​​​​Since 1989, the Recipient Epidemiology Donor Studies (REDS) program has been the premier research program in blood collection and transfusion safety in the United States. It supports research that will improve donor blood collection and make donor blood safer and available for the treatment of anemia in limited-resource settings.
  • NHLBI researchers helped develop treatments for aplastic anemia, a rare but serious blood disorder that occurs when your bone marrow cannot make enough new blood cells for the body to work normally. Aplastic anemia is treated with medicines called immunosuppressants that calm the immune system. However, immunosuppressants do not work well in about one-third of people who have aplastic anemia. To help solve this problem, the NHLBI led studies to show that eltrombopag, a medicine that helps the body make more blood cells, is an effective treatment option for aplastic anemia.

Current research on causes of anemia

NHLBI-supported research is helping scientists and doctors understand what causes anemia. For example, we fund projects to better understand how the body makes red blood cells in a healthy person and in a person who has anemia.

Other studies we support are exploring how race and serious health conditions such as obesity, kidney disease, and heart disease affect a person’s risk of anemia.

Supporting anemia research globally

The World Health Organization (WHO) estimates that about 42% of young children and 40% of pregnant women worldwide have anemia. NHLBI-funded studies have helped researchers develop effective low-cost tests to diagnose anemia and improve the safety and availability of donor blood used to treat anemia around the world.

Anemia research labs at the NHLBI

Anemia research labs at the NHLBI

Researchers from several NHLBI laboratories on the NIH campus are focused on developing new treatments for anemia, including:

Researchers in these labs study how the body makes blood cells and how the immune system contributes to anemia. Our researchers are also working on developing genetic therapies and other new options to treat anemia. Read more about these projects and ongoing clinical trials.
