Comparison of plasma-thrombin, HistoGel, and CellGel cell block preparation methods with paired ThinPrep slides in the setting of mediastinal granulomatous disease

Various cell block (CB) preparation methods are utilized by different laboratories, and not all laboratories perform CBs in tandem with ThinPreps (TPs). To compare the performance of different CB methods and their diagnostic value when used in conjunction with TP, we assessed the quantity and size of granulomas obtained from endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) of lymph nodes in the evaluation of...
