I was in a major car accident and was careflighted to ER trauma, I went to get medical records and saw that underv my drug screen it read on the alcoh?

Standard testing. Drug and alcohol levels are frequent in the clinical trauma arena. Motor vehicle incidents have high correlation to alcohol levels. What was the level? Intoxicating? Or not? Driver or passenger? Significant details.
It's OK. Drug screen most often read >7 alcohol even if you have not drank any alcohol. This is often insignificant so relax.
Routine Adm. Lab. Often Blood Alcohol and drug screens are drawn on admission to rule out head injury vs. drug effect.
