We forward samples to other laboratories for testing. In addition to alcohol in blood we can have samples analyzed for drugs. We facilitate DNA testing as well. We always provide a secure chain of custody.

Prior to forwarding blood for testing, the samples are carefully inspected for proper identification, expiration date, condition of the sample, proper seals and chain of custody. We provide you with our report as well as the report from the forwarded lab.

Formulate Alcohol Absorption and Elimination Profiles using the "Kinetics Model," which shows the BAC levels for the complete drinking episode.
Other models are also used. The Profiles might be used to show that the defendant was below the legal limit at the time of operation while being over the limit at the time of the test.


Provide you with a probability graph using analytical uncertainties to see if the independent test corroborates the State's test or not.

Review and critique analytical results produced by other laboratories.

Why use CGLabs?

From 1993 through 2017 CG Labs, Inc. specialized in the analysis of alcohol in Blood and Captured Breath. It was the concentration of our entire business.


The Laboratory was accredited by ASCLD/LAB-International in the category of Human Performance Forensic Toxicology (Blood/Alcohol only) until it became an LLC and no longer performed inhouse testing.

We are a small business providing friendly, personalized attention.
