Production of stained tissue sections for examination by light microscopy is a step-wise process which begins with preservation of tissue (fixation), then dehydration and clearing of the tissue, and finally impregnation with wax (processing). Mineralized tissues such as bone and teeth are subject to a further step (decalcification). Thin sections are then attached to a glass slide for staining and light microscopy.In the UK, it is usual for a preliminary diagnosis to be made using hematoxylin and eosin (H&E) staining. A definitive diagnosis may need further investigation with immunocytochemistry. All of these procedures must allow morphology and tissue structure to remain in tact, as any pathology present must not be compromised.
制作用于光学显微镜检查的染色组织切片是一个循序渐进的过程,首先是组织保存(固定),然后是组织脱水和透明,最后是用蜡浸透(处理)。骨和牙等矿化组织还需进一步进行脱钙步骤。然后将薄切片附着在载玻片上进行染色和光学显微镜观察。在英国,通常先用苏木精和伊红(H&E)染色进行初步诊断。明确诊断可能需要通过免疫细胞化学进行进一步检查。所有这些程序都必须使形态和组织结构保持完整,因为任何现存的病理学特征都不能受到损害。
