What tests revealed pathology?

Pathology can be revealed through various diagnostic tests, including imaging studies like X-rays, CT scans, and MRIs, which can identify structural abnormalities. Laboratory tests, such as blood tests, biopsies, and cytological examinations, can also detect cellular or biochemical changes indicative of disease. Additionally, endoscopic procedures can allow direct visualization and sampling of tissues. Collectively, these tests help in diagnosing and understanding the nature of the pathology present.
