FOR IMMEDIATE RELEASE

MEDTOX SCIENTIFIC RECEIVES FDA 510(K) CLEARANCE FOR ADDITIONAL
THREE DRUGS ON THE PROFILE®-V MEDTOXScan®

DRUGS-OF-ABUSE TEST SYSTEM

ST. PAUL, July 29, 2009 – MEDTOX Scientific, Inc. (Nasdaq:MTOX), announced today that on July 24, 2009, it received 510(k) clearance from the U.S. Food and Drug Administration (FDA) to market its PROFILE®-V MEDTOXScan® Drugs-of-Abuse Test System with three additional drugs - Oxycodone, Propoxyphene and Tricyclic Anitidepressants.

The total number of drugs detectable on the system is now twelve. The MEDTOXScan® READER and expanded panel is the broadest panel with the lowest detection levels available with any FDA cleared reader in the market place.

The PROFILE®-V MEDTOXScan® Drugs-of-Abuse Test System consists of the PROFILE®-V MEDTOXScan® Test Devices and the MEDTOXScan® Reader. The Test Devices are one-step immunochromatographic tests for the rapid qualitative detection of one or more of the following drug classes and cutoff concentrations in human urine:

AMP Amphetamine 500 ng/mL

BAR Barbiturates 200 ng/mL

BZO Benzodiazepines 150 ng/mL

COC Cocaine 150 ng/mL

MAMP Methamphetamine 500 ng/mL

MTD Methadone 200 ng/mL

OPI Opiates 100 ng/mL

PCP Phencyclidine 25 ng/mL

THC Cannabinoids 50 ng/mL

OXY Oxycodone 100 ng/mL

PPX Propoxyphene 300 ng/mL

TCA Tricyclic Antidepressants 300 ng/mL

The Reader provides accurate, easy-to-use and cost effective testing for drugs-of-abuse. Results are available in 10 minutes for improved turn around time. There is an optional attached bar-code scanner for accurate entry of user ID, patient ID and lot number of the device. Test results will remain on the digital display until cleared by the operator. A printer provides a paper copy of the results for a permanent record. The Reader also has network integration capabilities and enhanced record storage of 1,000 results with improved record management.

The MEDTOXScan® Reader includes a Positive QC Test Device, a Negative QC Test Device and a Cleaning Cassette. The Positive and Negative QC Test Devices are intended to detect potential errors associated with the Reader such as a contaminated contact imaging sensor (CIS) and to verify the CIS cleaning procedure using the approved Cleaning Cassette which effectively removes any contamination.

The Test System is intended for professional use in a hospital laboratory setting. Currently MEDTOX has between 300 and 400 hospital clients utilizing MEDTOX’s PROFILE® visually read cassettes for drugs-of-abuse detection. The new Test System will be marketed not only to those clients, but to the broader hospital market which is estimated in excess of 2,500 hospitals.
