A revolutionary drug test can detect amphetamines, cannabis, cocaine and opiates from the sweat of single fingerprint sample in just 10 minutes. In order to explore the relationship between fingerprints and oral fluid, patients were also asked to take an oral fluid test using a Quantisal™ collection kit . Analysis of oral fluid samples were carried out by Claritest .
- Research published in theRoyal Society of Chemistryexplains that “a small area of a single fingerprint” is enough for comprehensive analysis.
- A revolutionary drug test can detect amphetamines, cannabis, cocaine and opiates from the sweat of single fingerprint sample in just 10 minutes.
- The new test also does not involve taking samples of blood, hair or urine, making it less invasive and safer, Costa said.
- Good correlation of results was obtained using the Drug Screening Cartridge and the laboratory-based toxicology data for both blood and urine samples.
- The lateral flow Drug Screening Cartridge was able to successfully identify 19 of the 20 samples where opiates were found to be present in the sweat of a fingerprint.
I clearly shows that the lateral flow Drug Screening Cartridge can be successfully used to detect drugs of abuse from the sweat on the fingers of deceased individuals with a strong correlation to the results obtained using LC–MS-MS analysis. 2, and after following instructions, as directed by the Reader 1000 touch-screen, the results of the analysis of the test are displayed on the screen within 8 min of initiating the test. The result of each test gives a pass/fail for the presence of each drug, based on a cut-off for each analyte. For this study, the cut-offs for each drug detected using the lateral flow device were set at 190 pg for THC, 90 pg for BZE, 68 pg for morphine and 80 pg for amphetamine. The results obtained using the Drug Screening Cartridge and Reader 1000 can be printed to provide a permanent record.
Staff must obtain a clearance form from the Fingerprinting Office prior to visiting the Drug testing Office. All Money Orders must be made out to Miami Dade County Public Schools. The research was funded by a company eco sober house cost called Intelligent Fingerprinting, a company that does other fingerprint-based drug tests, and the UK’s National Institute for Health Research. The method can potentially be applied to a variety of substances.
Fingerprint drug screen test works on the living and deceased
The researchers plan to make a business case for the technique as a safe, rapid and highly accurate method of running a variety of drug tests in the real world. A team of researchers has developed a simple paper-based test that can in a matter of seconds detect whether a person has recently been using cocaine. Analysis of urine, oral fluid and fingerprints by liquid extraction surface analysis coupled to high resolution MS and MS/MS – opportunities for forensic and biomedical science.

Peter is well known for his expertise in investigation and aviation security.
Outside of its applications in law enforcement, fingerprint drug testing may help during asubstance abuse intervention. Institutions such as drug rehab in Florida could identify both the presence of drugs and the type. In a hospital setting, practitioners may get faster readings and know what they are dealing with in an overdose situation. A fingerprint drug test from Intelligent Fingerprinting is already available. The test uses lateral flow assay technology with fluorescence-labelled antibodies to selectively detect specific drugs or their metabolites in eccrine sweat collected from fingerprints.
Patient fingerprint samples
Operated via a simple touchscreen, the DSR-Plus takes just a few minutes to analyse the Drug Screening Cartridge and provides simultaneous results for each drug in the test. During the height of the pandemic, Bheodari was the most ardent supporter of our mission-critical employees. Having worked his way up through the ranks, he fully appreciates the oftentimes thankless jobs these employees perform that keep the Airport safe and running optimally at all times. Morale never flagged because Bheodari made sure those employees felt valued through hazard pay, special meals, social media posts, intranet spotlight features, and other incentives.
It is so easy to use that organizations including Eastern Airways have been able to adopt the train the trainer approach – where one person in HR for example has been trained to use the system and then can easily pass this knowledge on to others within the company. In recent work, Ismail et al. showed that cocaine could be detected in the fingerprints of drug users, and that it was possible to set a cut-off level to distinguish environmental exposure from cocaine use21. Our group has also researched rapid methods (~2 minutes per sample) for testing for cocaine from a fingerprint22,23, including paper spray mass spectrometry24, which we showed was compatible with visualisation of a fingerprint prior to analysis. This enables a sample to be collected, checked for authenticity and analysed within a timeframe of a few minutes.
An important observation is the detection of the metabolite, BZE in the fingerprint samples from donors who did not ingest cocaine. It has been hypothesised by ourselves and others4,15,22 that the metabolites of a drug can be used to confirm that a drug has been metabolised and excreted. These results show that the detection of a drug metabolite in a fingerprint provided from unwashed hands does not necessarily arise from drug ingestion. However, Fig.3 shows that after hand washing, whilst cocaine is still observed in the fingerprint samples provided by Donors 1 and 3, BZE is no longer detected.

New research published in the Journal of Analytical Toxicology shows how the Intelligent Fingerprinting Drug Screening System enables the detection of amphetamines, cannabis, cocaine and opiates from a single fingerprint sample in just ten minutes. “We have a first-class health and safety record, demonstrating our commitment to the safe operating environment that we provide to our employees and clients. Adopting the Intelligent Fingerprinting method is a major step forward in our drug testing and drug policy development,” Karl Griffin continued.
This undoubtedly leads to some variability, for example the intra donor variability that can be seen in Fig.6. This currently limits the ability to provide a quantitative test result based on a fingerprint, and will be explored in future work. However, the data presented here shows that in spite of this, it is possible to distinguish between touch and ingestion of cocaine in a drug testing scenario. The fingerprint test promises results in less than two minutes, saving time in testing cocaine use.
Can I fail a drug test?
Urine tests can occasionally return false-positive drug test results. Eating certain foods that contain the chemical compounds used in prescription or illicit drugs can cause a person to fail a drug test. Eating poppy seeds, for example, can technically throw up a red flag for suspected opioid use.
Two sets of fingerprints were taken from participants, both before and after they thoroughly washed their hands. The same process was then used to collect samples from a pool of non-users who had touched street cocaine. The DSR-Plus is a key part of our end-to-end fingerprint-based drug testing solution which, used in conjunction with the fingerprint Drug Screening Cartridge, provides a convenient initial drug screening test. We also offer a laboratory confirmation test using the Fingerprint Collection Kit for Laboratory Analysis, when a confirmed result is required in the event of a positive screening test. Mass per fingerprint of cocaine and benzoylecgonine detected in the fingerprints from 28 non-drug users, collected as presented and measured using paper spray mass spectrometry.
If a test shows non-negative at screening stage, a fingerprint-based laboratory confirmation service is available to identify the exact metabolite or analyte present and give expert opinion for any action that needs to be taken. Simply take another two sets of samples using the fingerprint collection kit for laboratory analysis. The researchers compared the results of their fingerprint assay against the more commonly used saliva test to see if there was agreement between them. Prior drug testing methods using fingerprints have only been able to demonstrate that a person had touched the substance, but not whether they had actually used the drug. But usually lab-based drug screening from start to finish typically takes 24 – 48 hours.
Amphetamines and their major metabolites, including 4-hydroxynorephedrine, are weakly basic low molecular weight compounds, and thus are able to diffuse through cell membranes relatively easily and can ultimately be found in sweat. Different drugs are metabolized by the body in a variety of ways, generating a plethora of metabolites, some of which are excreted through the sweat glands.

If a financial institution is SEC-regulated instead of FDIC-regulated, they are required to submit fingerprints directly to a Self-Regulatory Office for pre-employment fingerprint-based background checks. Our experienced teams handle the court record checks by going straight to the source (whether on-site at the courthouse) or through appropriate technology. For employment and education verifications, we will determine if the information is available in an approved database or will go directly to the source. Other data sources will depend on the searches requested as part of the background check. “The results from our coroner service trials also clearly demonstrate how our non-invasive fingerprint screen is simple to use, hygienic and offers an ideal complementary screening approach for the growing number of sectors that require a rapid and flexible drug test.” Its use in coroner mortuaries demonstrates the value of the system, which is also being used in drug rehabilitation centres and workplaces.
What does it mean when you test negative for a drug test?
A negative result on an initial drug test indicates that no evidence of drug use or misuse was detected in the urine sample. This may be because the patient hasn't used the specific drugs tested, because the patient last used the drug outside of its detection window, or because of problems in conducting the drug test.
Consistent with the work of Ismail et al. using LC-MS21, cocaine is detected at elevated levels in the patient samples compared with the “environmental” level. The fact that the “street cocaine” line is higher than the “cocaine powder” line is explained by the fact that these samples were taken immediately after contact with street cocaine, whereas for cocaine powder, samples were taken 3 hours after contact. For either situation, no clear distinction between ingestion and contact can be made on the basis of cocaine detection alone, even after the patient has washed their hands. Whilst previous work has explored the possibility of using a fingerprint to distinguish between cocaine ingestion and environmental exposure, there is currently no data on whether recent contact with cocaine can be distinguished from cocaine use.

Fingerprints have long been used by law enforcement to identify specific individuals. Thanks to innovations in technology, fingerprint testing can also be used to detect the presence of drugs. The technology, developed at the University of East Anglia, can detect extremely low amounts of amphetamines, cannabis, cocaine and opiate drugs from the sweat of a single fingerprint. The sample is taken in just 5 seconds and can be analyzed in 10 minutes using a portable device. A single fingerprint can distinguish whether someone has recently touched cocaine or actually ingested it. This test can be completed in less than 2 minutes, far quicker than blood tests, and could be used for forensic investigations or drug testing.
Mass spectral analysis was performed in positive electrospray mode with analysis performed in multiple reaction monitoring mode with a minimum of two MRM transitions selected for each analyte. The study set-up involved taking the specialized fingerprints from persons who were in treatment at drug rehabilitation facilities, as well as a control group of non-drug users. The subjects also followed a protocol to wash their hands before their fingerprints were taken on the special paper. As part of the process, the specific chemicals utilized also created a unique fingerprint of the subjects, as the ridges of the fingerprint were linked to the identity of the donor. Enterprise Advantage offers worldwide employment background checks via a configurable online system giving you consistency of processes and visibility into your program worldwide.

The accuracy for THC, BZE, MOR and AMP was 98.7%, 94.7%, 96.0% and 93.3%, respectively, at the cut-offs of 190 pg/fingerprint for THC, 90 pg/fingerprint for BZE, 68 pg/fingerprint for morphine and 80 pg/fingerprint for amphetamine. They also took fingerprints from 26 people at a drug rehabilitation clinic who reported taking cocaine in the past 24 hours. It’s important to select a drug test that best meets your company’s drug policy requirements, as different test methods have different windows of detection. Several types of lateral flow assays exist with minor differences in their details of the operation. Generally, cellulose or paper-based material is used to support a mixed layer of molecules that will form complementary pairs with the analytes of interest in a sample.
All full-time instructional, non-instructional, administrative and temporary instructors must take a drug test. The applicant must appear at one of the approved location sites prior to the expiration date noted on the general Drug Test Authorization form. Failure to comply with the expiration date requirement will result in disqualification of employment eligibility or any further consideration for employment by Miami-Dade County Public Schools for a three year period. Harrow Council in the UK has https://sober-home.org/ successfully trialied a drug-test technology that uses fingerprints alone. They have also added a fingerprint identification step to the process, which in a real-world application would ensure the sample came from the person meant to take the test. “It can detect cocaine and metabolites of which is further proof that cocaine has gone through the body and is excreted,” said lead researcher Catia Costa, a researcher at the University of Surrey in the United Kingdom, in an interview with CNBC.
