Comparison of Bone Marrow Aspiration Cytology, Touch Imprint Cytology and Bone Marrow Biopsy for Bone Marrow Evaluation at a Tertiary Health Care Institute
Bone marrow is one of the most widely distributed organs in the body which contains hematopoetic cells as red marrow and adipose tissue as yellow marrow. It produces cellular components of blood like red cells, white cells and platelets1. Bone Marrow Aspiration Cytology (BMA), Bone Marrow Biopsy (BMB) and Bone Marrow Imprint (BMI) (TOUCH IMPRINT) cytology are the methods to examine bone marrow. Cytological picture is given by BMA and BMI however cellularity is less in BMI while cytological picture and architecture is better studied by BMB. For studying marrow cellularity examination of core biopsy is the gold standard2. Bone marrow examination is useful investigation in diagnosis and staging of several haematological diseases, for assessment of overall bone marrow cellularity and morphology, even for diagnosing, non haematological disorders and unexplained abnormalities of any peripheral blood cell type3.
