The Pathology Bone Marrow Request involves obtaining and submitting the patient’s bone marrow samples extracted from the hip or sternum for diagnostic purposes. A bone marrow aspirate or tissue sample collected is subjected to detailed analysis of bone marrow cells, tissue morphology, special staining, and genetic analysis. This study is essential in diagnosing, staging, and prognosticating hematological disorders, including leukemia or nonmalignant blood abnormalities.
