Aplastic Anemia (AA)

This disease occurs when the "mother cells" (from where all the blood cells come from) located in the bone marrow are low or absent, which leads to a low or absent number of blood cells in the circulation. It can be either inherited (like Fanconi anemia), acquired (exposure to a variety of drugs, chemicals, radiation and some viruses) or idiopathic (unknown cause).

It presents with symptoms associated with anemia like fatigue; may also present as recurrent infections, easy bruising and bleeding.

The diagnosis is usually made with a combination of blood tests and bone marrow tests. Other tests may be necessary in order to find the cause of the aplastic anemia.
