Autopsy vs. Necropsy: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
An autopsy is a thorough examination of a body after death to determine cause of death, while a biopsy involves removing tissue from a living body for diagnosis.
Key Differences
An autopsy is a post-mortem examination performed to determine the cause of death, typically involving a thorough analysis of the entire body. In contrast, a biopsy is a medical procedure that involves taking a small sample of tissue from a living body for diagnostic purposes.

Autopsies are used to understand both the immediate cause of death and underlying health conditions. Biopsies, however, are used to diagnose or rule out certain conditions, such as cancer, by examining tissue or cell samples under a microscope.

During an autopsy, various organs and systems of the body are examined, and samples may be taken for further analysis. Biopsy procedures vary in invasiveness, from needle biopsies, which are relatively simple, to surgical biopsies, which are more complex.
