Urine Alcohol Testing

What is urine alcohol testing and how is it performed?

Urine alcohol testing is typically performed to show recent alcohol use. The difference between breath alcohol testing and urine alcohol testing is in the detection times. For breath alcohol testing to show a donor as being positive, a donor must be under the influence of alcohol at the time of the test, while urine alcohol testing does not have this requirement. Depending on the amount of alcohol consumed and the frequency of consumption, urine alcohol testing can detect alcohol use up to 72 hours in the past.

Urine samples are typically collected in a closed bathroom or bathroom stall while the collector waits outside of the bathroom unless the test is to be observed. In observed testing, a trained observer of the same gender will accompany the donor into the bathroom or bathroom stall and will ensure that the donor does not tamper with or substitute their sample.

Who should choose urine alcohol testing?

Urine alcohol testing is usually performed when recent alcohol use is suspected. This type of testing is also very common in alcohol use monitoring programs in which a donor is required to test multiple times per week to ensure that no alcohol has been consumed. Alcohol use monitoring programs are typically implemented in cases where there is a history of the donor abusing alcohol and that donor wishes to have custody or visitation with their children. These types of monitoring programs are also useful to sober living facilities and housing.

Urine alcohol testing requires that the donor provide approximately 45 milliliters of urine (about 1½ ounces), so individuals who are undergoing certain medical treatments or problems may not be able to test if the treatments or problems affect their ability to provide a valid urine specimen.

Urine alcohol testing has been used successfully in legal proceedings and alcohol use monitoring programs implemented by individuals and the courts.

How we can help.

We can provide urine alcohol testing services that are confidential and court defensible. Urine alcohol testing services are available to concerned parents, attorneys, corporations and private individuals. Results can be released to multiple individuals if necessary.

In situations where donors are living in other states or even overseas, we can coordinate the collection of their samples where each donor resides.

Have Questions?

Alcohol testing can be difficult. We understand.

Normally urine alcohol testing is performed by donors who have a documented history of alcohol abuse. Alcohol use monitoring programs are an inconvenience to the donor, can be embarrassing and in cases where the donor has succeeded in recovery, it can make them feel untrustworthy. In addition to the embarrassment that goes with taking an alcohol test and the potential feelings of untrustworthiness, you have the added anxiety of waiting for the test result to come back. Even if a donor knows the result should be negative, it can still be a major source of anxiety, especially if their ability to visit their children is at stake. We understand all of this. We also understand that you will have questions and concerns. We want you to know that we will be here each step of the way to help you, even after the test results are back. If you have any questions about the testing process, help interpreting your results or would like information on how to join Alcoholics Anonymous or where alcohol abuse treatment can be obtained, please give us a call, we are here to help.
