Interpretation of Results

Ethanol levels are typically reported in mg/dL (milligrams per deciliter) or g/dL (grams per deciliter). The effects of ethanol vary by concentration:

Ethanol Level (mg/dL)	Clinical Effects
0 – 10 mg/dL	Normal, no alcohol or minimal presence
10 – 50 mg/dL	Possible mild impairment
50 – 100 mg/dL	Noticeable intoxication (euphoria, reduced coordination)
100 – 200 mg/dL	Significant impairment (slurred speech, poor balance)
200 – 300 mg/dL	Confusion, nausea, severe intoxication
> 300 mg/dL	Potential for coma, respiratory depression
> 400 mg/dL	Fatal risk due to alcohol poisoning
