The test method in question is also known as the screening, and represents a type of medical analysis of a person’s urine sample for the purpose of discovering the presence of alcohol, which would reveal if the person in question has been drinking or not. In addition, this method can also be employed to establish the exact time frame within which this person has consumed alcohol. It is also one of the ways authorities (i.e. the court) can keep track if a person who has been ordered to “lay off the booze” is actually following this order in a consistent manner. Having standard urine test in mind, it needs to be pointed out that its main purpose is to discover the presence of alcohol concentrating on the time span of 6 to 24 hours after the person in question has consumed it. For this test to be successful, this person is required to provide a urine sample discharged into a sterile container. After this has been done properly, by means of a detecting card, alcohol presence is determined. But this is not the final phase, for this is also verified in a laboratory, where results are to be verified before presented officially.
The efficiency of the urine test depends on quite a number of factors, which can influence to a great extent its successfulness. For one, the time stretch encompassing the moment alcohol was consumed up until the moment it was detected by an alcohol test is the most significant among all the factors, and the one that will influence those final results immensely. When the chemical substance is finally discovered (which can take up to two hours), the testing for a variety of durations is also performed for the purpose of getting more precise results. Yet another quite important part of the initial urine test is the extension test, whose goal is to discover the presence of Ethyl glucuronide in the person’s urine, i.e. a chemical substance known to be one of the byproducts of alcohol, previously metabolized by the person’s body. This way, it can be discovered if alcohol has been consumed over a much longer period of time – 80h all the way to five days, giving a much better overall image of the person’s alcohol consumption and habit. But, due to fairly expensive equipment, the test in question is far less employed.
This specific test is regarded as the most frequently employed by numerous agencies and companies that seek to discover if their employees are performing work chores under the influence of alcohol, or even if they are drinking it during working hours. Another reason for its frequent employment is the fact that such a test is extremely easy to conduct, for no professional staff is required since urine samples can be acquired easily, and then sent on to the official laboratory for testing.
