A superior method for cell block preparation for fine-needle aspiration biopsies

Cell block (CB) techniques for fine-needle aspiration biopsies (FNABs) vary. A direct comparison of CB techniques with statistical validation was performed to identify the best method.Three CB techniques were compared: 1) FNAB rinsed in saline and clotted with plasma and thrombin (SPT); 2) FNAB rinsed in formalin and clotted with HistoGel (HG); and 3) FNAB rinsed in formalin, centrifuged, and the pellet captured in a collodion bag (ColB). FNAB...
