Detection ranges from 0.02% through to 0.30% for the approximate relative blood alcohol concentration. The test gives an accurate, quantitative result with saliva. Can be used by non medical staff, no false positives, results in 2 minutes. Ideal for one-off occasions when you would like to check someone, and perfect for off-site checks or when you are out of the office.
