Vitreous humor is strongly recommended as a body fluid for determination of ethanol in postmortem toxicology to help establish whether the deceased had consumed ethanol before death. Variability of blood alcohol content (BAC) determinations: the role of measurement uncertainty, significant figures, and decision rules for compliance assessment in the frame of a multiple BAC threshold law. Blood Serinelli S, Bonaccorso L, Furnari C, Gitto L. Acad Forensic Pathol. This percentage would represent the maximum estimation of the BAC at the time of the accident. The universally accepted blood alcohol concentration There is a case report of methanol toxicity being mistaken for ethanol intoxication due to use of a breathalyzer, where the methanol in the breath was mistakenly detected as ethanol by the device leading to delayed diagnosis[21]. An example of a situation in which specific intent is a requirement is burglary, defined as the illegal breaking and entering of a dwelling with the intent to commit a further felony.
