Diagnosis process of biopsy needle
Dec 28, 2021
The histopathological diagnosis process of biopsy is generally to observe the submitted specimens by naked eyes → take materials → (fix, embed) → make thin sections → perform hematoxylin-eosin (HE) staining → observe under an optical microscope. Through the analysis and identification of diseased tissues and cell morphology, combined with visual observation and clinical related data, the diagnosis of various diseases can be made. However, for some difficult and rare cases, it is also necessary to perform auxiliary diagnosis through histochemistry, immunohistochemistry, electron microscopy, or molecular biology techniques on the basis of the above-mentioned routine examinations.
