Complete blood count
A complete blood count checks the red and white blood cells, blood
clotting cells (platelets), and sometimes, young red blood cells (reticulocytes). It
includes hemoglobin and hematocrit and more details about the red blood cells.
Peripheral smear. A
small sample of blood is checked under a microscope. Blood cells are checked to see
if they look normal or not.
Blood tests of genes and
Blood samples are taken and checked for abnormal genes and
chromosomes. This is a test called a chromosomal breakage assay.
Bone marrow tests. Samples of
bone marrow are taken and checked for decreased and abnormal blood cells.

require many different medical specialists. Your child will get treatment based on
symptoms. Stem cell transplants offer the only cure for Fanconi anemia. Treatment
Blood transfusions. This

Fanconi anemia may lead to:
- Delayed growth or development
- Certain cancers, such as leukemia,
cancers of the head and neck, and cancers of the female reproductive system
