Abstract

|
The forensic pathologists or medical examiners involved in the investigation of medicolegal cases can expect to come across cases of negative autopsy. One may consider that when no cause of death is found at the postmortem table the autopsy is, negative.
An autopsy is considered to be negative when all efforts, including gross and microscopic studies and toxicological analyses, fail to reveal a cause of death. Theoretically speaking, there must be a cause of death, but in practice it is not possible to establish the true cause of death in every case.
A negative autopsy may result from one of the following factors.
1. Autopsy carried out without adequate history.
2. Lapses in external examination
3. Inadequate or improper internal examination.
4. Insufficient histological examination
5. Lack of toxicological and other investigations.
6. Pathologist´s training.
