Diagnostic Assessment of Bone Marrow Aspiration Smears, Touch Imprints and Trephine Biopsy in Non- Haematological Disorders.

Diagnostic Assessment of bone marrow aspirate particle smears, imprints and biopsy sections was done on 10 Non- Haematological disorders. Core needle biopsy of the bone marrow is a safe and useful procedure. It is a valuable diagnostic aid for measurement of marrow cellularity, metastatic tumours and fibrosis . Bilateral trephine biopsy was conducted wherever necessary. Touch imprints were useful for studying cell morphology, where aspiration yielded dry tap.All the three procedures of bone marrow aspiration, trephine biopsy and touch imprints were found to be complementary to each other and superiority of one method over the other depended on the specific disease process.
