What is the primary purpose of a pathological examination?

The primary purpose of a pathological examination is to diagnose diseases based on tissue examination. This process involves the microscopic evaluation of biopsies and surgical specimens to identify any abnormalities or disease processes present in the tissues. Pathologists analyze the characteristics of the cells and tissue architecture to determine whether a disease is present and, if so, what type it may be. This diagnostic information is crucial for guiding treatment decisions and informing patients about their health status.

In contrast, while treating diseases is an important aspect of patient care, it is not the focus of a pathological examination itself, which is centered on diagnosis. Collecting blood samples is a part of laboratory practices rather than pathology specifically, as pathology predominantly deals with tissue. Conducting preventive screenings falls under the realm of public health and clinical practice, rather than the diagnostic focus of pathology. Hence, identifying disease through tissue examination remains the hallmark of pathological examination.
