Is it possible to confirm presumptive positive results?
To confirm a presumptive positive result, send the original leftover oral fluid specimen to Forensic Laboratories for confirmation by gas chromatography/mass spectrometry (GC/MS). Place the security seal over the screw cap, put the collection chamber in a security bag and mail to Forensic Laboratories. Results are available by fax, email, or U.S. Postal mail. For laboratory support, please contact our Client Services Department at (800) 282-6574.
