Urine Tests And Chemical Testing

What is involved in a chemical test. Alcohol concentration is defined as the number of grams of alcohol per 100 milliliters of blood, the number of grams of alcohol per 210 liters of breath, or the number of grams of alcohol per 67 milliliters of urine. You may be asked to supply your urine as part of your sobriety test at the police barracks. It should be noted that each of these three tests is different and conflicting results can occur. This means that potentially, your urine test could find you innocent while your breath test could find you intoxicated.

When a police officer suspects you of drinking and driving, he or she will ask you to submit to a chemical test. There are three: blood, breath and urine. Of the three, the breath test is used most often by police officers because it is an easy device to transport and can be used during the traffic stop.

Of the three, a urine test can be one of the best options for a defendant. This is because the results are often questionable. Your DUI defense attorney can point out the weaknesses in a urine test as grounds for your defense. A urine test does not determine the concentration of alcohol in a person's system or whether or not the person was illegally impaired. At this point its best to first contact legal counsel.

It is important to note that the legal limit of .08 is determined at the time the test was administered, and usually this is not at the time of driving. It can be anywhere from 30 to 75 minutes later. Therefore, a test reading can be off, in relation to whether the driver was intoxicated while driving, which is the crime. In other words, if you had two drinks in 30 minutes, then left right away, chances are your BAC would not register the two drinks if you were pulled over. It would probably only register one.

However, you would not be given the breath test right there, but instead, at a later time when your BAC could be higher since your body has had time to process the alcohol. As a result, you would be charged with a DWI even though when you were actually driving, your body had not registered the alcohol yet and you were not influenced by it.

For any legal questions you may have or if you have been stopped for a DWI then contact me immediately.
