The first instant, lateral flow EtG test optimized for alcohol abstinence monitoring

Note: For forensic use or export only.

Express Diagnostics is excited to offer the first onsite, lateral flow test for Ethyl glucuronide (EtG) – a unique biomarker of alcohol use – optimized for abstinence monitoring. 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.

The 500 ng/mL cutoff of the new DrugCheck Rapid EtG dip test is widely considered to be the optimal cutoff for Ethyl glucuronide 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.

DrugCheck Rapid EtG Dip Test

Advantages of DrugCheck Rapid EtG, the only instant, lateral flow EtG test available in the U.S.

  • Fast: Dip test in specimen for 15 seconds
  • Negative results can be read in less than 1 minute, as soon as both the control and test lines have formed
  • Positive results stable for 2 hours
  • Shelf life of 2 years from date of manufacture
  • No cross reaction after use of mouthwash or hand sanitizers
  • Patent pending

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, as soon as the control and test lines have formed. 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.

U.S. pricing and cost comparison

DrugCheck Rapid EtG cost per unit compares very favorably to lab-based EtG testing regimens, with pricing at any quantity a fraction of the cost of traditional laboratory testing. Cases contain 25 units.

Significant cost savings

Agencies conducting abstinence monitoring with Rapid EtG, coupled with low flat-rate ($15) EtG lab confirmation through Express Diagnostics' Lab Services partner, can realize significant cost savings.

Performance characteristics

Express Diagnostics’ Ethyl glucuronide (EtG) test was evaluated in comparison to a commercially available EtG Enzyme Immunoassay Test (EIA). All positive samples were confirmed by Liquid Chromatography - Mass Spectrometry (LCMS).

Sensitivity: 96% — Specificity: 98.67%

Interpret results

drug test results interpretation image

Negative: Colored lines are visible in both the control (C) and test (T) zones, indicating that concentration of the drug is below the detection limit of the test or not present.

Note: The test line (T) may have varying intensity, either weaker or stronger in color than that of the control line (C). However, any indication of a line in the test region should be interpreted as a negative result.

Presumptive Positive: One colored line is visible in the control (C) zone. No colored line whatsoever appears in the test (T) zone, indicating a presumptive positive result.
