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.
A sample with a negative result for alcohol shows no change from the original light yellow color on the test strip pad. Urine with alcohol at specific levels will be indicated on the test strip pad according to the color on the easy-to-read color chart.
Urine alcohol is available in single-dip format, as well as numerous configurations of the following devices:
- NxScan flat-panel cup — up to 14 drugs of abuse, alcohol and/or adulterants
- NxStep round cup — up to 15 drugs of abuse, alcohol and/or adulterants
- Dip Drug Test — up to 14 drugs of abuse, alcohol and/or adulterants
