Urine alcohol testing

Note: For forensic use or export only.

Urine is the most practical specimen for alcohol testing, particularly when the purpose of testing is to demonstrate that alcohol consumption has occurred. Peak urine alcohol levels are reached 45 to 60 minutes after alcohol ingestion. At this time, urine alcohol levels are typically approximately 1.3 times greater than the corresponding blood alcohol concentration. This ratio is only valid during the elimination phase, which occurs after the blood alcohol level has peaked and is decreasing. Alcohol may be detected in the urine for 1 to 2 hours longer than it is detected in the blood.

Interpretation of Results

NEGATIVE : No color change appears on the reaction pad. The color should match the color block on the color chart corresponding to a negative (-) result. This indicates that alcohol has not been detected.

POSITIVE: A color change appears on the reaction pad. The color on the reaction pad varying from a light blue to a dark blue, falling on or between the corresponding color blocks on the color chart. This indicates that alcohol has been detected.
