The best way to make imprints of the bone marrow biopsy. The morphology is excellent, the spacial relationship of the cells and the marrow architecture are represented, and there is no hemodilution affecting the differential counts. You can quickly and efficiently make several imprints at the procedure. As you you roll the biopsy, the smears get thinner....which guarantees an ideal selection for morphology, special stains, and FISH testing, if needed.
