How to Diagnose This Condition?

The following tests help to diagnose aplastic anemia.
Blood Tests- Red blood cells, white blood cells and platelets stay within normal range normally. In aplastic anemia, all these three levels remain low.
Bone Marrow Biopsy - The doctor uses a needle to remove a small sample of bone marrow from the large bone in the body such as the hipbone. Then the sample is examined under a microscope to rule out blood related diseases. In aplastic anemia, bone marrow contains fewer blood cells than normal. So confirming the diagnosis of aplastic anemia requires a bone marrow biopsy.
