How does ihc immunohistochemistry enhance biomarker analysis?
Immunohistochemical techniques visualize biomarkers through specific antigen-antibody reactions, significantly enhancing the accuracy of pathological diagnosis. Studies have shown that when IHC is used to detect HER2 protein expression, its sensitivity reaches 98.7% and its specificity exceeds 95%. Compared with the 60% interpretation consistency of traditional HE staining, IHC increases the diagnostic coincidence rate to 92%. …
