Rejection Histology

Rejection histology refers to the microscopic examination of tissue, usually a transplanted organ, to identify signs of rejection. When someone receives an organ transplant, their immune system may attack the new organ, causing damage that can be seen under a microscope. Pathologists look for specific cellular changes, such as increased immune cells or tissue injury, to determine if rejection is occurring. This analysis helps doctors decide whether to adjust medications to protect the transplanted organ and ensure its continued function.
