Express Diagnostics receives patent for onsite saliva drug test

February 4, 2015

Express Diagnostics Int’l today announced that its patent for the DrugCheck® SalivaScan™ Oral Fluid Drug Test, titled “Device for Verifying Analytes in Bodily Fluids,” was approved by the European Patent Office. The patent is currently pending with the U.S. Patent and Trademark Office (USPTO Patent Publication Application Number: 20130022517).

“I am more than elated to announce that the first of many patents for the DrugCheck SalivaScan Oral Fluid Drug Test – the European patent – has been granted and published,” says Paul Johnson, CEO of Express Diagnostics Int’l, Inc. “This is a significant milestone for Express Diagnostics. The granting of this patent, and the expected forthcoming U.S. patent, represents another asset in our intellectual property portfolio and in the value we are gaining as a company.

“With the issuance of the European patent, we fully expect the U.S. patent – the most valuable patent – to be granted and published in early 2015.” Adds Johnson, “Again, this is a great accomplishment for Express Diagnostics. I’d like to thank everyone for their work in both the product development and patent application processes, and most importantly, for our customers’ continued support of this innovative product.”

Leading features of the DrugCheck SalivaScan include an integrated sponge saturation indicator in the collection swab that notifies test administrators when sufficient specimen has been collected. Determining adequate specimen according to the color change on the indicator strip helps reduce the potential costs of test failure due to insufficient specimen often associated with competing saliva devices.

The collection swab locks into the DrugCheck SalivaScan for a tamper-evident seal. The device can then be sent to a laboratory for confirmation, on a presumptive positive result. Dual side extraction ports simplify specimen access for laboratory personnel.

The device can screen simultaneously for up to 10 drugs of abuse, with 16 total available, including market-leading cutoffs, or detection levels, for buprenorphine, cotinine, EDDP, ketamine, and methadone. Express Diagnostics manufactures the DrugCheck SalivaScan at its ISO 13485:2003-certified facility in Blue Earth, Minn.

The DrugCheck SalivaScan is for Forensic Use or export only. Forensic Use in the U.S. is limited to criminal justice or government agencies, including correction centers, court systems, jails, police departments, probation offices, the Department of Defense, U.S. military, and laboratories performing forensic testing for these entities.

Express Diagnostics was founded on October 4, 2004, by CEO Paul Johnson, COO Rich Strasser, and three additional partners. As distributors of DrugCheck® onsite screening devices through their respective companies, the founders recognized the opportunities available with the purchase of the DrugCheck brand, which was completed at the inception of the company.

From its founding with one full-time employee, Express Diagnostics has grown to employ over 100 people, manufacturing product for distribution partners in over 60 countries, including distributors with exclusivity in Australia and Mexico. EDI also has company representatives in California, Colorado, Massachusetts, and Strasbourg, France.

The production processes employed by Express Diagnostics are some of the most advanced in the industry and, coupled with continual product innovation and skilled staff, provide customers 100% U.S.-made, cost-effective alternatives to devices manufactured in traditionally low-labor-cost countries.

“The company’s success can be attributed primarily to our distributor partners, dedicated staff, and a supportive community,” says Johnson. “Express Diagnostics has grown significantly in the decade since its founding thanks to our discerning customers and staff, and the support of Blue Earth area residents and businesses. Our continued success is directly tied to the efforts of these folks and we thank them.”

In its 10 years of operation, EDI has been a consistent leader in drugs of abuse and alcohol testing with first-to-market urine tests for alcohol, K2/Spice, gamma-hydroxybutyric acid (GHB), and Ethyl Glucuronide (EtG), a unique biomarker of alcohol use. Express Diagnostics has also been named to the Inc. 5000 list of fastest-growing companies in the U.S. the last two years in a row.

Express Diagnostics launches the first-ever instant, lateral flow test for EtG

May 27, 2014

Express Diagnostics Int’l today announced the launch of the first-ever onsite, lateral flow test for Ethyl glucuronide (EtG), a unique biomarker of alcohol use. EtG testing previously has been available only through laboratories, at significant cost and several days in transit and processing. The new DrugCheck® Rapid EtG™ (Patent Pending) urine test delivers accurate, reliable results in as little as one minute, at a fraction of the cost of lab-based EtG tests.

Express Diagnostics initiated development of the DrugCheck Rapid EtG point-of-care test in 2013 and leveraged partnerships globally to be able to offer the test to the U.S. market. It has the potential to be one of the most transformative tests in the industry since the development of instant, onsite drug tests in the 1990s. Express Diagnostics has partnered with a leading firm in the marketing of drugs of abuse testing to facilitate sales and distribution of the DrugCheck Rapid EtG test in the U.S.

“Express Diagnostics is very excited to bring the first-ever onsite, lateral flow EtG test to market. Compared to the typical process, whereby tens of thousands of specimens nationwide are shipped each day for lab-based EtG tests, our new Rapid EtG test offers unheard of flexibility and efficiency for alcohol abstinence monitoring,” says Paul Johnson, CEO of Express Diagnostics. “The tremendous cost and time savings that the DrugCheck Rapid EtG offers administrators will be truly transformative for those organizations currently testing for EtG, not to mention the additional forensic-use markets that will now employ EtG testing due to the superior convenience, accuracy, and speed of this instant test. DrugCheck Rapid EtG is a true ‘game changer’ in onsite testing!”

Alcohol is the most commonly abused substance worldwide, but it is also the most difficult to detect via abstinence monitoring where alcohol consumption is prohibited. Abstinence monitoring is conducted in a range of environments, from criminal justice, probation, and parole, to treatment centers and the military. Because alcohol is rapidly cleared from the body, detection times in traditional alcohol (ethanol) testing are limited to a few hours after use, and therefore of limited use in abstinence monitoring. In contrast, EtG is a unique biological marker of alcohol use that can be detected up to 80 hours after alcohol ingestion.

EtG testing was first offered by laboratories around 2005 and was soon recognized as one of the most significant tools available for abstinence monitoring. While use of EtG testing grew initially, concerns over potential false-positive results from inadvertent, environmental alcohol exposure, such as mouthwash and hand sanitizers, began to limit use of the test. More recent research and development has advanced both the science of EtG testing and the understanding of appropriate cutoffs, or detection levels, for accurate detection of the alcohol biomarker.

The 500 ng/mL cutoff of the new DrugCheck Rapid EtG test is widely considered to be the optimal cutoff for EtG testing for abstinence monitoring. Positive results at the 500 ng/mL threshold for Rapid EtG are consistent with recent ingestion of alcohol — up to approximately 48 hours prior to specimen collection. Studies also indicate that positive results at this cutoff are not associated with incidental alcohol exposure, such as from mouthwash or hand sanitizer.

To perform a test with the DrugCheck Rapid EtG, simply dip the test strip into a urine specimen for 15 seconds. Negative results can be read in as little as one minute. Positive results are interpreted at 5 minutes and are stable for two hours. The test has a shelf life of two years from the date of manufacture.

The DrugCheck Rapid EtG test is for forensic use only and is intended for use only in alcohol abstinence monitoring for law enforcement, including correction centers, court systems, jails, police departments, probation offices, and other law enforcement organizations.
