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 alcohol test just like this: 25* < 10 mg/dl can you explain this reading, I am confused because I had no alcoholic drinks! I did have over the counter cough meds due to I had a horrible cough due to my allergic asthma and had no prescriptiom medication for it...
