Today, there are many different systems that are used for measuring a person's alcohol levels. Some of these procedures include the breath test, urine test, and the blood test. On the other hand, these tests are not created equally and some technics are far more precise than others. If you are looking for some helpful information on breathalyzers exactitude, this article can help.
There are different types of urine tests that are used to detect the amount of alcohol in a person's system. Typically, the urine test looks for the presence of ethyl glucuronide, but new research shows that some of these tests are usually too sensitive to be deemed accurate or useful. Fortunately, this type of analysis is used far less often than the breath and blood tests.
Breath tests are performed with machines called breathalyzers and are usually used by law enforcement officers. These tests are very easy to administer and require the subject to breathe into a mouthpiece in order to be tested. Once the device has received a large enough breath sample, it provides the user with a result.
The precision of breathalizer varies widely according to a number of factors. For example, professional breathalyzers are more precise than consumer grade breathalyzers. Also, the final reading is affected by the calibration of the device, the temperature of the air, and the subject's breathing patterns.
Blood tests are usually considered to be the most perfect alcohol test around. There are very few factors which can lead to a false result via a blood test. In most cases, the only reason for a false result would be lab error.
Alcohol analyzer preciseness ultimately depends upon a number of different factors. The type of test that is used, the way in which the test is administered, and local weather conditions can all affect the final result. If you are ever in doubt about your results, opt for a blood test instead.
