Alcohol testing identifies the presence of alcohol or its metabolites in a person in order to assess either current intoxication or consumption of alcohol in the past. Evidential breath alcohol testing can instantly determine the current level of alcohol in the breath, and by proxy, the blood. On the other hand, urine, blood, and hair specimens can be examined in a laboratory to identify prior alcohol consumption with varying sensitivities and windows of detection, going back as far as 3 months.

Since the various types of alcohol drug tests look at different time periods, they are therefore appropriate for different circumstances. Thus, the decision of which alcohol screening to order should be guided by the needs of the person or organization ordering the test, or the type of alcohol use they are attempting to prevent or detect.

About Alcohol Testing

Urine Alcohol Tests


Urine alcohol tests (such as EtG tests) detect the presence of alcohol metabolites, indicating consumption of alcohol, either presently or in the recent past. A positive result is not necessarily indicative of current intoxication, but it does show that alcohol was consumed. A basic urine alcohol screening checks for consumption in the most recent 12 hour period, whereas an EtG alcohol test can pick up consumption over the past 70 to 80 hours, i.e., the past 3 days. Urine alcohol tests are typically ordered to ensure someone has remained abstinent from alcohol. Courts, divorcing parents, and rehabilitation programs frequently request basic or EtG tests.

Breath Alcohol


Breath alcohol tests (commonly called breathalyzers) are administered by a technician in which results are provided right on the spot. Evidential Breath Testing devices (EBTs) are the gold standard in breathalyzers. The results of a breath alcohol test that is conducted using an Evidential Breath Testing device (i.e., an EBT) can be used in a court of law.

Breath alcohol tests (BATs) detect the current presence of alcohol in the bloodstream. Police use BATs, commonly called breathalyzers, to detect drunk driving - and the results are court admissible if conducted using an EBT. Private parties, employers, and divorced or divorcing parents frequently order breath alcohol screenings when the other party is required to be sober at the current time – such as when operating heavy machinery, taking custody of minor children, or performing safety sensitive duties.

Blood (Peth) Alcohol Tests


The blood alcohol screening known as the Peth test determines if someone has been binging or using alcohol regularly over a period of time roughly equivalent to the prior 3-4 weeks.

Alcohol Testing vs. Drug Testing


An alcohol test is different from a drug screen in small – but important – ways. First and foremost, as everyone knows, alcohol is legal to purchase and consume for adults over the age of 21. Drug tests, on the one hand, typically look for evidence of illegal drugs consumed in the past several days (in the case of urine screens) or in the past several months (in the case of hair tests). On the contrary, because alcohol is perfectly permissible in most private settings, employers testing for alcohol should only examine what’s currently in the system; in other words, they measure for the immediate presence of alcohol in the body.

In private cases, such as court orders or agreements between former spouses to remain alcohol free for the safety of the children, it is often necessary to look back for the presence of alcohol. In those situations, Health Street can determine if alcohol was consumed over the past 70 to 80 hours using a urine test, 3 weeks for a blood test, or 90 days using a hair follicle screening.
