Can doctors tell if you die from antifreeze poisoning?

Yes, doctors can tell if you die from antifreeze poisoning. Antifreeze poisoning causes characteristic findings in the body tissues and fluids like the presence of ethylene glycol crystals in the kidneys and elevated levels of ethylene glycol and its metabolites in the blood and urine. These findings, along with the patient's symptoms and medical history, help doctors diagnose antifreeze poisoning.
