A fingerprint drug test can detect heroin without taking blood



A fingerprint test developed at the University of Surrey can tell whether a person has taken heroin or not.

Using high-resolution mass spectrometry technology to detect heroin, 6-monoacetylmorphine (6-AM), and other class A-associated analytes, the technology can identify heroin traces on human skin, even if it does the case is washed their hands.

It is also wise enough to distinguish the degree of exposure of a person to the drug, whether it has used it, or shaken only the hand that dealt with it.

Researchers took fingerprints of ten people who had been treated in rehabilitation clinics in the last 24 hours and had taken heroin or cocaine. A fingerprint was collected from each finger of the right hand and participants were asked to wash their hands thoroughly with soap and water and then wear nitrile gloves for some time before releasing another set of fingerprints.

The same procedure was used It was used to collect samples from 50 people who were not drug users.

The technology was able to identify traces of heroin and 6-AM in the hands of participants who in a number of scenarios were not drug users ̵[ads1]1; whether they had touched it directly, touched it and then washed their hands or one's hand shaken another, who had come in contact with the drug.

This information was referenced with the data of drug users. Additional chemicals such as morphine, noscapine and acetylcodeine were present in the fingerprints of those who had actually taken heroin, as the drug is broken down in the body.

Blood tests are traditionally used to prove that someone has taken a medicine. However, these results indicate that this information could instead be obtained by a simple, non-invasive fingerprint test.

The researchers believe that this technology could be used to monitor compliance with prescription drugs.

Dr. Melanie Bailey, forensic lecturer at the University of Surrey, said: "Our team here at the University of Surrey believes that the technology we've developed makes our communities safer and shortens the path for those in need of their addictions to fight. We believe that the technology is also used in other areas, such as: As in the confirmation of whether a patient takes his medication. "
