A molecular pathologist is a physician who focuses on the study of diseases by analyzing blood, organs, tissue, or other bodily fluids at the molecular level. This kind of testing is vital in identifying and treating diseases, especially when determining between illnesses with similar symptoms. For example, Type I and Type II diabetes both elevate blood sugar levels and have other related symptoms, but the causes are different, and the two diseases should be treated with distinct medical plans. The differences between the two conditions are often detected at the molecular level. As a molecular pathologist, your job duties include examining tissue or organ samples, analyzing the data to help diagnose illnesses, suggest treatment plans, and keep accurate records and documentation on your findings.
