A groundbreaking drug test developed from research conducted at the East Anglia University makes it possible to detect four classes of drugs in traces of sweat found in a fingerprint. And technology works for both the living and the dead.
New research published in the Journal of Analytical Toxicology shows how the intelligent fingerprint drug screening system allows the detection of amphetamines, cannabis, cocaine and opiates from a fingerprint sample in just ten minutes .
The technology also works when it is used by British coroners to detect sweaty drugs from fingerprint samples collected from deceased people.
Founded in 2007, Intelligent Fingerprinting is a company derived from the UEA. The drug screening system works by analyzing the sweat of a fingerprint sample.
Unlike conventional screening methods that require the collection of saliva or urine samples, the technique is noninvasive, dignified and non-biohazardous.
Its use in coronary mortuaries demonstrates the value of the system, which is also used in drug rehabilitation centers and workplaces. Studies are also underway on its use in airport control and offender management applications in prisons and probation services.
Professor Emeritus David Russell of the Faculty of Chemistry at UEA has been co-author of the research and is the founder and scientific leader of Intelligent Fingerprinting.
"This new study shows how our lateral-flow drug-screening cartridge can quickly detect drug use in individuals by using a fingerprint sample with a sampling time of only five seconds and a total scan time of ten minutes.
"Our study also showed how coroners used our technology to better understand the potential cause of death, inform future post mortem activities, or facilitate police investigations.
"We compared the results of the coroners with our fingerprint test to a second laboratory-tested sample, which provided an excellent correlation in terms of accuracy," he said. -he adds.
"We also compared our results with the toxicological analysis of blood and urine samples, with a good correlation of results."
"This important research shows that a person's fingerprints, whether alive or dead or sweaty, are sufficient to allow our finger-based drug testing system to detect the simultaneous presence of four major drugs, "Added Dr. Paul Yates of Intelligent Fingerprinting.
"The results of our coroner service trials also show how easy and hygienic our non-invasive fingerprint screen is and is an ideal complementary screening approach for the growing number of areas requiring a blood test. rapid and flexible screening.
"Drug testing with sweat of a fingerprint: detection of lateral flow of Δ9tetrahydrocannabinol, cocaine, opiates and amphetamine "is published in the Journal of Analytical Toxicology.
