Pathology is the study of disease, including the causes, processes, and effects of disease on the body. Pathology procedures are the methods used by pathologists to diagnose and understand disease. These procedures play a critical role in the diagnosis and treatment of disease, providing important information about the cause, progression, and effects of disease on the body.
A tissue biopsy is a common pathology procedure that involves the removal of a small sample of tissue from the body for examination under a microscope. This type of procedure can be used to diagnose a range of conditions, including cancer, infections, and autoimmune disorders.
Laboratory tests, such as blood tests, urine tests, and stool tests, are commonly used in pathology to diagnose and monitor disease. These tests can help to identify the presence of disease-causing agents, such as bacteria, viruses, and cancer cells, as well as changes in the body’s chemistry and function that may indicate the presence of disease.
Imaging tests, such as X-rays, CT scans, and MRI scans, are also used in pathology to visualize the internal structures of the body and diagnose disease. These tests can help to identify the presence of abnormal growths, such as tumors, and changes in the structure of organs and tissues that may indicate the presence of disease.
An autopsy, also known as a post-mortem examination, is a pathology procedure that involves the examination of a dead body to determine the cause of death. Autopsies can help to identify the presence of disease, determine the cause of death in cases where the cause is unclear, and provide important information about the progression and effects of disease on the body.
