Answer:
Yes. A Colorado DUI blood result may be challenged when the collection, handling, storage, or testing process did not comply with required health-department regulations.
Colorado DUI blood draws must follow regulations intended to produce fair and accurate results. Those rules address how the sample is collected, handled, stored, and analyzed.
When a technician or laboratory fails to follow the required procedures, the reliability of the reported blood-alcohol result may be challenged. The defense may examine records, chain of custody, testing methods, and the qualifications of the people involved.
A Denver DUI lawyer can review the blood evidence and determine whether a regulatory violation supports suppression, exclusion, or a challenge to the weight of the test.
