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

Yes, there are a number of poisons that are not detectable on an autopsy. Common poisons that can evade detection include those that are absorbed into the body quickly, such as poisons that are ingested, injected, or inhaled. Some poisons, such as some venoms, can also take an extended amount of time for symptoms to appear, meaning an autopsy would not necessarily reveal the presence of poison in the body. Finally, some poisons, such as some bacterial toxins, can be destroyed by the body's own defenses and thus would not be detected by an autopsy.
