Blood and Urine Evidence in DUI Cases

While blood and urine evidence can be very powerful in a DUI case, it by no means indicates that the prosecution’s case is ironclad. Indeed, an experienced Sacramento DUI attorney may be able to uncover a problem with the state’s evidence.

Doing so will require a fair bit of investigation. He may need a description of the procedure used for the test, as well as any notes that the technician made during the test. He may also request the test results for any controls used in the test, which are known solutions used to establish a baseline in the testing equipment. If the test was conducted in a large laboratory, it may be necessary to check the chain of custody for your sample. Most labs have strict requirements as to who is allowed to handle the sample. Your attorney may also request the evidence that the technician who administered the test has been trained in its use. If an error with the sample or the test administration itself can be uncovered, the results may be invalid.

Failing that, the DUI attorney may be able to uncover problems with the test equipment itself. To these ends, he may request maintenance information for the test equipment, and verification that the vial containing your sample was sterile. If there appears to be a serious problem, the DUI attorney may be able to obtain a portion of the sample leftover after the test, which is called the split, to be retested.

An experienced Sacramento DUI attorney can make all the difference when the state has a case that appears to be ironclad. Make sure you have one on your side: call dedicated Sacramento DUI attorney Param Pabla today for an initial consultation.
