An alcohol test is a forensic screening that identifies the presence of alcohol or it's metabolites in a person in order to assess either current intoxication or a history of prior consumption. Professional breath alcohol testing can instantly determine the current level of alcohol in the blood. On the other hand, urine, blood, and hair specimens can be tested in a laboratory to identify prior alcohol consumption with varying sensitivities and windows of detection. Different types of alcohol tests are appropriate for different circumstances. Call (888) 378-2499 to discuss your alcohol testing needs.
