Tennessee DUI Urine Tests

Of the three major types of chemical testing—breath, blood and urine—urine is the least accurate gauge of blood alcohol content. This is due to the three-phased cycle of alcohol consumption: absorption, distribution and elimination.

Three Phases Of Alcohol Consumption

During the absorption period, the alcohol level in your blood increases. BAC levels plateau in the distribution period, and finally fall during elimination.

Alcohol content in urine is at its highest during the elimination phase—about 1.3 times higher than the correlating blood alcohol content. This means that while it is possible to obtain a blood alcohol content reading via a urine sample, it simply will not be an accurate reflection of your true BAC.

False Positive Urine Test

It is possible in certain situations to obtain a false positive for alcohol when performing a urine test. Diabetics or people suffering from yeast or bacterial infections may have a false positive reading for alcohol in their urine sample.

Urine Sample Storage

Urine must be stored at the proper refrigeration level, or the sample will be rendered useless.

Consult An Experienced Criminal Defense Attorney

If you have been charged with DUI and were asked to submit to a urine test, you should consult with an attorney immediately to discuss the handling and administration of the test. A knowledgeable lawyer will be able to examine the results and the way the test was administered to determine whether the results show an accurate reading.
