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.


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.

Expert testimony in the fields of gas chromatography and pharmacokinetics of alcohol metabolism (alcohol absorption and elimination)
