Immunohistochemistry (IHC) is an advanced diagnostic technique used to identify specific proteins in tissue samples using antigen-antibody reactions. It plays a crucial role in cancer diagnosis, classification, and prognosis. Dr. Akanksha Raj Khandal uses immunohistochemistry to differentiate tumor types and determine targeted treatment options. IHC enhances diagnostic accuracy by providing molecular-level insights beyond routine histology. This service supports personalized medicine by guiding oncologists in selecting appropriate therapies. Immunohistochemistry is also valuable in identifying infectious agents and autoimmune conditions. Its precision makes it an essential tool in modern pathology and advanced disease diagnosis.
