Overview

The bone marrow biopsy is the gold standard test for the diagnosis of aplastic anemia. A hematopathologist will review the bone marrow biopsy findings, and confirmatory results for aplastic anemia include hypoplasia with <20% cellularity, normal maturation of all cell lines, presence of fat cells and stroma in bone marrow space. Residual hematopoietic cells are morphologically normal. Hematopoiesis is not megaloblastic.
