DUI blood-test “anomalies” cause review
State officials are reviewing DUI blood-alcohol tests after “anomalies” — variances between private laboratory results and state test results — were found recently.
The Colorado Bureau of Investigation is working with the Colorado Department of Public Health and Environment to review discrepancies identified by ChemaTox Laboratory, a private Boulder firm, in blood samples collected by law enforcement during DUI investigations, according to CBI.
A CBI and CDPHE review found 56 anomalies out of more than 1,500 DUI blood tests done since July 1, 2015.
“There is no indication that any defendant was inappropriately charged with an offense based on test results showing an erroneously high level of alcohol in a driver’s bloodstream,” the CBI said in a news release.
ChemaTox became aware of a discrepancy in November, when the lab was notified by a defense attorney of a wide variance between its test result, which it did on behalf of the defense attorney’s client, and the CBI’s test result in the same case.
ChemaTox notified the CBI of the variance in December.
KCNC- Channel 4 in Denver first reported on the variances Monday.
The CBI and CDPHE review is ongoing.
