paraffin method

paraffin method

(in surgical pathology) a method used in preparing a selected portion of tissue for pathological examination. The tissue is fixed, dehydrated, and infiltrated by and embedded in paraffin, forming a block that is cut with a microtome into slices 8 μm thick. This method, which is more commonly used than the frozen section method, is slower and therefore not used during surgery.
