New fingerprinting technology can detect class A drug use

Diterbitkan : - Kategori : Sober living

In these experiments, participants were asked to touch a pre-weighed mass of cocaine (0.5 mg or 2 mg) and spread the powder over all their right-hand fingers for approximately 10 seconds. Participants then dusted the excess off to remove large particles, and deposited fingerprints using the same procedures described above for both “as presented” and “after handwashing”. Fingerprint-based drug testing provides a quick and easy, non-invasive and dignified alternative to traditional point-of-care drug testing methods such as saliva and urine testing. As the system is portable it can be easily taken out for testing – at a client’s home for example – for spot check adherence to court orders, or to avoid vulnerable / shielding clients having to come into busy offices. The team, from University of Surrey, Forensic Science Ireland, National Physical Laboratory and Intelligent Fingerprinting, took fingerprints from people seeking treatment at drug rehabilitation clinics who had testified to taking cocaine during the previous 24 hours.

The fingerprint method was chosen ahead of urine and saliva tests because it easier to use on site, with results available on site in 10 minutes. John Wicks is one of the UK’s leading experts in drug testing and has been for over 25 years. He is CEO and co-founder of Cansford Laboratories, a drug and alcohol testing laboratory based in South Wales. John is one of the ‘original expert minds’ who alongside co-founder Dr Lolita Tsanaclis, is responsible for bringing hair testing to the UK.

  • Latest findings show how a single fingerprint left at a crime scene could be used to determine whether someone has touched or ingested class A drugs.
  • In contrast, MSI techniques can separate hotspots from the main fingerprint matrix.
  • After contact with cocaine, the signals corresponding to cocaine and BZE do not correlate spatially with the ceramide image and are observed as discrete hot spots, as clearly demonstrated in Fig.
  • The fingerprint sample is dissolved during the test process and, as the Cartridge is non-biohazardous, it can be disposed of in normal waste after use.

Crown Roofing and Cladding’s own well-trained staff will carry out the random tests in-house as required, acting as a deterrent to help underpin the company’s drug and alcohol policies. Due to the high-risk work at height that it carries out, Crown Roofing and Cladding has a zero-tolerance approach to drugs and alcohol misuse. The company researched and purchased the Intelligent Fingerprinting test to enable on-site, in-house drug testing, along with an alcohol breathalyser to ensure everyone is safe at work.

The rapid, non-invasive fingerprint method replaces a traditional off-site urine test approach. Together with operational and efficiency savings resulting from Intelligent Fingerprinting’s 10-minute test, the switch to the fingerprint method is set to save Wilco Southwest eco sober house price $20-25,000 CAD annually. The non-invasive drug screening system from Intelligent Fingerprinting is easy to use, and will enable CGL to determine in minutes if a client has recently used any of the four drugs in the test – amphetamines, cannabis, cocaine and opiates.

The programme has been in play for a few months now and the response from our employees has been extremely positive – we’ve even had volunteers as they are intrigued by the innovative fingerprint-based testing technology. We’ve now adopted Intelligent Fingerprinting into our health and safety and wellbeing policies, and randomly test a part of the business every 12 weeks,” he added. Part of the Wilco Group, the largest civil and landscape development group in Western Canada, has adopted the Intelligent Fingerprinting Drug Test to use in its recruitment process.

The “paper spray mass spectrometry” technique is becoming more popular in forensics because it is very sensitive and the testing system is very simple to set up. Researchers have created a unique kind of paper to take the fingerprints which are then used to uncover the metabolites with an accuracy of 99%. We spoke to Paul Yates, from Intelligent Fingerprinting, about a new innovative and less invasive approach to drug testing. I’m a big believer that we should always be looking for new technologies and ideas that will help people who use our services. Even in a world without coronavirus, we’d still want to be using fingerprint testing, but it’s also a really useful way of overcoming the challenges of the pandemic.

  • 5 hours A two-year run of sales growth for construction product manufacturers has ended, manufacturers report.
  • For organisations such as Family Drug and Alcohol Courts there is a requirement for parents to agree to take part in regular drug testing in order to maintain child custody.
  • The Scheme is a not-for-profit organisation founded by the construction industry to improve its image.

The digital screen on the DSR-Plus reader displays a negative or non-negative screening result for each drug in the test within 10 minutes. Images of cocaine and its metabolite in a fingerprint are analysed and the relationship between these molecules and the fingerprint ridges are explored. It is then possible to tell the difference between a person who has ingested a drug and someone who has only touched it. The world’s first fingerprint-based drug use confirmation test has been launched by Impington company Intelligent Fingerprinting. Fingerprint Drug Testing Equipment is compact, light and portable, for convenient drug screening whenever it’s needed, in a variety of locations. At a crime scene), it may be possible to deduce whether or was deposited after a donor had used or consumed cocaine.

West Yorkshire Police trial handheld scanners which allow them to identify people in less than a minute with potential massive efficiency boost. As part of its ongoing support for the decarbonisation of the electrical industry, Legrand … Cllr Christine Robson, Portfolio eco sober house cost Holder for Children and Families, said “As always our focus is upon the best interests of the children, young people and their families. The fingerprint test will allow police, prison officers etc. the ability to quickly tell if someone was using cocaine.

• End-to-end solution – fingerprint-based laboratory confirmation service available. This fingerprint test is now being used for the first time to detect drugs and the results of the technique are 99% effective for identifying cocaine in patients. This new fingerprint test is revolutionary for these workers and they can get results in real-time with a drug test that is non-invasive and will give definitive results in just a few minutes. For organisations such as Family Drug and Alcohol Courts there is a requirement for parents to agree to take part in regular drug testing in order to maintain child custody. Intelligent Fingerprinting’s Drug Screening System is very applicable for this type of testing as its shorter detection ‘window’ screens for possible drug use in the day prior to parents’ regular meetings at council premises.

  • In the trials, participants were asked to wash their thoroughly, before being asked to provide another fingerprint sample later.
  • In these challenging times, it was not an option, or advisable, to test people using ‘normal’ methods.

We’ll start with 50 sites across our clinical services, then roll it out more in two waves over the coming weeks, until all our clinical sites in England have the equipment. Because fingerprint testing pilots have been a success, we began to think about how we could roll it out across Change Grow Live services. While we were working out the best way forward, the coronavirus pandemic changed everything.

Sample collection

Dr Melanie Bailey is a fellow of the Engineering and Physical Sciences Research Council . Her team has identified differences between the fingerprints of people who touched cocaine compared with those who have ingested the drug, even if the hands are not washed. We saw a clear opportunity for using this technology to test people who are new to treatment, in response to social distancing and shielding. In these challenging times, it was not an option, or advisable, to test people using ‘normal’ methods. We’ve already changed the way we prescribe medication to make things safer for people, but in order to reduce risk, there might still be a need to test people. An experimental fingerprint detection approach can identify traces of cocaine on human skin, even after someone has washed their hands – and the test is also smart enough to tell whether an individual has actually consumed the class A drug, or simply handled it.

Dragon LNG, a company responsible for receiving, storing and regasifying Liquified Natural Gas at its Pembrokeshire terminal in Wales, is the first organisation in the international gas industry to deploy a revolutionary new fingerprint-based drug testing technology. By trialling the test with volunteers, scientists were able to determine if a person had taken the drug. Or, if they had come into contact with the drug unidirectionally, perhaps by just shaking hands with a heroin user or dealer. In the trials, participants were asked to wash their thoroughly, before being asked to provide another fingerprint sample later. The company now has plans to roll out the in-house testing approach to promote positive adherence to its drug and alcohol policies across construction sites in Ireland and other European sites.

5E shows the distribution of Na+ for a selected area of the fingerprint, which clearly shows the pore structure. 5E, the cocaine signal in this region is also presented, showing that the cocaine co-locates with the pores of the fingerprint. That measure only the mass of cocaine and metabolites deposited in a fingerprint, will be unable to determine whether the donor had used the illicit drug or simply encountered a contaminated surface.

Last month, the company announced it had appointed Derby-based SureScreen Diagnostics, a leading provider of workplace drug and alcohol testing services, as a UK distributor for its system. Meanwhile, in its latest World Drug Report 2020, the United Nations Office on Drug and Crime reports that as of 2018 approximately 5.3% of the global population aged 15–64 had used illicit drugs in the previous year. There are an estimated 19 million cocaine users globally, and an all-time high production of cocaine. With this increase in illicit drug consumption and production, there is increasing interest to gain forensic intelligence on drug distribution and drug use.

The fingerprint-based drug screening system is a quick, hygienic and easy-to-use approach to drug testing that works by analysing fingerprint sweat to detect drug use. MALDI images of a fingerprint sample collected from a participant who touched 0.5 mg cocaine hydrochloride powder is presented in Fig. Paper spray analysis of the cocaine powder used in this experiment showed the presence of BZE, explaining the presence of this metabolite in this fingerprint sample.5 This is further supported by the co-localisation of the cocaine and BZE signals shown in Fig.

Currently available cocaine drug testing kits require the user to give urine, blood or saliva. These substances have to be properly stored and disposed of as they are potential bio-hazards. An introductory video demonstrating fingerprint-based drug testing in action is availablehere.

For operational use, future work would be required to establish whether analytes are delocalised after the fingerprint is developed by routine forensic procedures. The drug treatment agency Change, grow, liverecently announced that it was piloting an innovative new approach to drug screening. Fingerprint testing may well be a great option to have for analysing drug use over a short-term period, say one to two days, but the hair test remains the better option when determining drug profiles over a longer period of time. New and exciting, there appears to be little difference between this and other point of care testing methods like blood, saliva or urine testing. Our offering allows the use of Intelligent Fingerprinting products both in our pharmacies or at the place of your work to make drug testing simpler and more convenient for everyone, whether you are administering a test or providing a sample.

The other major advantage is the almost immediate feedback which enables worker and service user to celebrate progress or modify their approach to tackle any relapse. In fact, this method could encounter problems over and above other testing practices as it uses such little sample material. This, again, could cause delays and issues when waiting for the sample to be confirmed. Open Access Government produces compelling and informative products for a wide audience.

Several drug screening cartridges are available, including the DSC 5-Plus which screens for opiates, methamphetamine, cocaine and cannabis, and the DSC 8-Plus which screens for opiates, methadone, benzodiazepines and buprenorphine. At first the test was set up for amphetamine, opiates, cocaine and cannabis, but through close working with Change Grow Live, they were able to develop the technology to respond to the need for clinical safety testing. We piloted clinical safety testing at Spectrum Drug & Alcohol Recovery Service in Stevenage, and people really liked it. The people receiving support from the service liked that it was less invasive and more discreet, and staff liked that it was quick, easy, and didn’t create loads of clinical waste. The Cartridges use lateral flow assay technology – similar to a pregnancy test – to detect specific drugs or their metabolites in the sweat collected from fingerprints. We propose that the spatial distribution of cocaine and its metabolite, BZE in a fingerprint can be used to discriminate between administration and dermal contact.
