Pathology Home Page

Pathology is the study of disease. A pathologist, who is a medical doctor, looks at the causes of disease, how disease progresses, and how disease affects the body. However, instead of examining the patient physically, a pathologist examines body fluids and tissue samples from that patient to help the primary physician make a diagnosis.

Most people have had some blood and urine tests done during their lifetime. These tests are analyzed by pathologists to help determine the next step in a patient's treatment plan.

Laboratory tests of almost any nature are performed to accomplish the following:

• establish or confirm a diagnosis
  
  
• rule out diagnoses
  
  
• help determine a treatment plan
  
  
• monitor a disease and how it responds to treatment
  
  
• screen for any underlying disease or risk factors

Laboratory tests are performed in both independent and hospital-associated laboratories, which are under direction of pathologists. Medical laboratories can be categorized into two divisions:

• Clinical Pathology
  Clinical pathology is the study of disease through evaluation of the body's biochemical processes, such as the production of hormones, enzymes, and other substances. Clinical pathologists analyze blood, urine, and other body fluids.

• Anatomical Pathology
  Anatomical pathology is the study of disease by examining tissue samples obtained through surgery or an autopsy from specific parts of the body. Anatomical pathology helps determine the cause and effects of a particular disease.
