Specimen-specific cell-blocking approaches.

The science of CellBlockistry highlights requirement for proper approach to process different types of cytopathology specimens with critical considerations during preparation of cell-blocks. Common cytopathology specimens which may be subjected for cell-blocking include FNA aspirates in addition to anterior fat pad aspirate, bone marrow aspirate, effusion fluids, and other fluids such as various washings and urine. In addition veterinary sciences and research fields including animal experiments and tissue/cell cultures may also be cell-blocked for improved diagnostic yield and research outcome.
