Alcohol testing can be done through urine, blood, saliva, hair, or breathalyzer tests. Each has pros and cons, with urine being the cheapest but less accurate, and blood being the most accurate but expensive and invasive. Saliva is a preferred option, while hair testing can detect alcohol use over time. Medications can affect blood alcohol levels. Testing can be done for law enforcement, employers, schools, doctors, and courts.
A drug test is a test done on your saliva, blood, or urine to detect the levels of alcohol in your system. It can be performed by law enforcement agencies to catch drunk drivers or prospective employers in order to ensure a clean workplace. Other reasons for alcohol testing are for schools to know students’ alcohol status, for doctors to confirm whether patients with certain conditions drink alcohol, and for the courts to know if a defendant drinks regularly.
There are several main ways authority figures can test for alcohol. These include urine tests, blood tests and saliva tests. Each of these has pros and cons that should be taken into consideration. Various methods can be used in combination with each other if the results are questioned.
The first type of drug test is a urine test. It is performed by having the person concerned urinate into a cup or, less commonly, the urine may be withdrawn through a catheter in a hospital setting. This is the cheapest type of alcohol test, and the results are usually accurate when taken within a few days of the person’s last drink. However, problems with the test do arise, such as patients drinking high levels of fluids before a test to dilute the level of alcohol present.
Another common problem with a urine drug test is that the person performing the test may need to be observed while urinating to ensure that a donor sample is not being used. This can be invasive and embarrassing for some people. Also, these tests aren’t always accurate in determining how often or how much a person drinks.
A saliva drug test is often the preferred choice because taking a saliva sample is less invasive and can be done by anyone. It is also as effective as a blood or urine test at detecting blood alcohol levels. While samples can still be swapped or swapped as with urine samples, this becomes much less likely if the swab is done on site by a test administrator.
Hair testing can also be a means of testing blood alcohol levels, as can the use of a breathalyzer. Using hair for the test is very accurate, although more expensive than a saliva test, and can detect alcohol use over time. The breathalyzer is most commonly used by law enforcement and requires the person to blow into a device which then gives a blood alcohol reading. This is relatively effective, but can only provide details about a person’s alcohol levels at a given time.
Blood tests, while accurate, are the most expensive way to determine a person’s alcohol levels. They are used to determine how much alcohol is in someone’s blood and can often detect very small traces of alcohol to show that the person was drinking at any given time. However, this is not always the case, especially in those who do not drink often or in large quantities.
The disadvantages of a blood alcohol drug test are that there are factors that can skew the results. Some medications can artificially raise blood alcohol levels. Blood alcohol testing is also the most invasive form of testing and can only be conducted by a qualified medical professional.
