Currently, the DCI Criminalistics Laboratory has the capability to screen blood samples for the drugs listed below and is performing confirmatory analysis on blood samples for only alcohol, inhalants, amphetamines, and cannabinoids. Any other positive blood screening results must be considered presumptive. For positive screens not confirmed by this laboratory, it is recommended that the sample be sent to a private laboratory for confirmation. Arrangements and expenses for sending the sample to a private laboratory must be made by the submitting agency. The DCI Laboratory website has a list of Private Laboratories Testing which may be used for these analyses.

This laboratory is working to develop further confirmatory analysis capabilities for drugs in blood and will notify customers of the laboratory when additional confirmatory tests are available.
