The evaluation of treatment efficacy in histology involves several key methods:
1. Histopathological Examination: This involves studying tissue samples to observe changes at the cellular level. It can help determine whether the treatment is reducing tumor size, promoting tissue repair, or mitigating disease symptoms.
2. Immunohistochemistry (IHC): IHC is used to detect specific antigens in cells by using labeled antibodies. This method can help quantify the expression levels of biomarkers before and after treatment, providing evidence of efficacy.
3. Electron Microscopy: This technique offers high-resolution images of tissue samples, which can reveal ultrastructural changes in response to treatment.
