Immunohistochemistry (IHC) **

Immunohistochemistry (IHC) is a test used to check for specific proteins in cells. Each type of cell has its own unique proteins, and these proteins can indicate whether the cell is normal or abnormal, such as a cancer cell. This test uses antibodies, which are substances that can recognize and bind to specific proteins on cells. When an antibody binds to a protein, it produces a color or light, allowing doctors to observe it under a microscope. IHC helps doctors diagnose many conditions, including cancer (differentiating between types of cancer), infections (identifying the causative agent), and autoimmune diseases (detecting antibodies attacking the body's cells). As a result, IHC is an important test in modern medicine, helping to accurately diagnose diseases and make effective treatment decisions.
