Parole uses a number of ways to test people for alcohol. Alcohol can be tested for up to two days in the body and this is done so in a number of ways
Blood testing can test the level of blood alcohol in the body and can be used to test whether a person has drunk alcohol for up to two days. This is generally expressed as a fractional percentage of alcohol to blood. Each state may define the amount of alcohol in the bloodstream or blood alcohol content differently. For example California defines blood alcohol content in grams, whereas others do so in millilitres. Blood tests can be costly and sometimes need to be performed and analysed by a medical professional.
Saliva tests are also increasingly common with parole boards. Saliva tests can measure the blood alcohol content for a few hours previously to up to two days. A quick swab of the inside of the suspect’s mouth is taken and analysed. However saliva tests may only work for short periods of time after consumption and so are not as commonly used as breathalysers.
The breathalyser test is the most common test for alcohol in the body.  Aside from accuracy one of the most important things about the breathalyser test is its speed. The test has a virtually immediate calculation and so takes little time, cost or analysis to produce a result.
Blood tests do need to be followed up with a blood sample as they are only an estimate of the blood alcohol content. Some states use breath test as evidence while others don’t accept them as evidence and just as a estimation of blood alcohol levels.
These are the three main types of test for alcohol that parole use. As it shows it depends on the state or country in which the individual is on parole.
