The post mortem report serves as a critical document in medico-legal investigations, with the primary goal of establishing the cause, manner, and time of death. While a thorough autopsy entails a detailed examination of both the exterior and interior of the body, the viscera examination report occupies an important, though not definitive, role in informing the final conclusions.

The viscera examination report specifically involves the analysis of internal organs and bodily fluids. This analysis is essential for identifying toxins, detecting underlying diseases that may not be visible during the initial examination, and understanding the physiological effects of injuries.

In cases where poisoning is suspected, the viscera report is invaluable. Toxicological analysis of samples from the stomach, liver, kidneys, and blood can identify the presence and nature of toxins, directly contributing to the determination of the cause of death in the post mortem report.

Likewise, in suspected infections or metabolic disorders, examining organs such as the lungs, heart, and brain can reveal crucial information that might not be apparent through external observation.

However, the post mortem report is not solely reliant on the viscera examination report. A skilled forensic pathologist synthesizes data from various aspects of the autopsy, including external findings (injuries, markings), internal findings (organ abnormalities, signs of disease), the crime scene investigation, clinical history (if available), and other supporting investigations like radiology and histology.

In many instances, a reasonable determination of the cause of death can be made even before the viscera report is completed. For instance, a gunshot wound to the head or severe trauma resulting from a motor vehicle accident may provide a clear indication of the cause of death based on the readily observable findings.

Moreover, the viscera examination has inherent limitations. Not all toxins are easily detected, particularly if a significant amount of time has passed between exposure and death, allowing for metabolism and elimination. Similarly, some natural diseases may not produce noticeable macroscopic or microscopic changes in the organs.

Consequently, a negative viscera report does not automatically exclude poisoning or a natural cause of death. In such cases, the forensic pathologist must place greater emphasis on circumstantial evidence, clinical records, and other investigative findings to reach a well-supported conclusion in the post mortem report.

The importance of viscera examination in post-mortem reports varies depending on the circumstances: in cases of suspected poisoning, a high concentration of pesticide in the stomach and liver can provide strong evidence to support the conclusion of poisoning-related death; however, when a clear cause of death like fatal stab wounds is evident during the internal examination, the post-mortem report can confidently state sharp force trauma as the cause of death even before toxicology results are available, although the viscera report may subsequently rule out other contributing factors; conversely, in SIDS (Sudden Infant Death Syndrome) cases, the viscera examination may not reveal a clear cause, and the post-mortem report will then rely heavily on excluding other potential causes through investigation of the scene and clinical history to arrive at a diagnosis.
