Are there any poisons that aren't detectable on an autopsy?

Yes, some poisons can be difficult to detect on an autopsy, such as cyanide and certain drugs. The amount and method of administration can determine the likelihood of a positive autopsy result. Additionally, certain toxins may take hours or days to begin showing symptoms, making it difficult to accurately pinpoint the time of death. In instances where a person is poisoned with a highly-concentrated toxin, the autopsy may not be conclusive. Furthermore, certain poisons, such as radiation and biological agents, cannot necessarily be detected at all through traditional autopsy practices. Ultimately, whether or not an autopsy will reveal any poisons cannot be determined in advance.
