RESUMEN
Microwave energy is produced from electricity energy via a magnetron which is discovered about 60 years ago and according to its several capabilities, is used in most industries. One of them is laboratory utility, especially in pathology laboratory, which was introduced in 1980 decade by Boon et.al. Microwave doesn't use in IRAN because ofexpensivity. Histoprocessing in pathology laboratory takes time about 24 hours and diagnosis is delayed one working day. For reducing time in diagnosis and decreasing hospital and insurance costs, and introducing an applicable way, the aim of this study is microwave oven usage in optimal tissue processing. ln this study, each level of processing was done separately and finally all the levels were combined then results were verified. According to details of tissue processing total time for all levels was 70 minutes. Distinction between each paithem was impossible and in many of them, microwave processing slides were better. Microwave processing could be used simply by pathology laboratories for reducing time ofhistoprocessing if correct calibration and setup is done
