Why do fluids must be measured in a autopsy?

In an autopsy, fluids must be measured to gather critical information regarding the cause of death and any underlying health conditions. Analyzing bodily fluids such as blood, urine, and cerebrospinal fluid can reveal toxic substances, pathogens, or abnormal levels of electrolytes and metabolites that may indicate disease or poisoning. Additionally, fluid levels can provide insights into the person's hydration status and any potential trauma. This data is essential for forming a comprehensive understanding of the circumstances surrounding the death.
