Alcohol concentration in DWI is defined by the statute as:
1) the number of grams of alcohol per 100 milliliters of blood; or
2) the number of grams of alcohol per 210 liters of breath; or
3) the number of grams of alcohol per 67 milliliters of urine.
As per the two statutory definitions of intoxication, it is possible for a person to be innocent of one definition and yet guilty of the other.
Of course, being innocent of one definition can be used to show reasonable doubt under the other.
