Applications of Chuangxing Model RDTD19H Trace Hair Drug Detector
As a key component of the National Key R&D Program of the 13th Five-Year Plan for Research on Technologies and Equipment for Drug Interdiction and Drug User Control , the trace hair drug detection technology has been developed through dedicated research and technological breakthroughs by the R&D team of Jinan Chuangxingweier Electronic Technology Co., Ltd., which successfully created the trace rapid hair drug detector.
Chuangxing's trace rapid hair drug detector adopts quantum dot fluorescence detection technology. Featuring simple operation, easy portability and convenient sampling, it enables non-invasive testing with no risk of pathogen infection and is adaptable to various testing environments. The entire detection process takes no more than 10 minutes, which greatly improves the efficiency and accuracy of drug testing work and makes up for the shortcomings of existing urine and saliva testing methods in drug detection.
Chuangxing's trace rapid hair drug detector not only provides technical support for public security and anti-drug authorities in determining drug addiction, but also monitors the treatment efficacy and detoxification progress of addicts, offering technical backing for community drug rehabilitation and recovery work. In accordance with relevant legal provisions such as the Measures for the Determination of Drug Addiction (Decree No. 115 of the Ministry of Public Security and the Ministry of Health), a "determination of drug addiction" shall be conducted for suspected drug abusers. This determination refers to the process by which public security organs or entrusted drug rehabilitation medical institutions judge whether a drug user is addicted and the severity of the addiction through biological sample testing, collection of drug use evidence, and assessment of physiological, psychological and mental symptoms and signs.
Q: Why is trace hair drug detection technology regarded as an advanced technology for identifying the severity of drug addiction? A: In the practice of anti-drug and drug rehabilitation work, saliva, urine and other bodily fluids are the most common samples for drug testing. However, the intermediate metabolites of drugs remain in bodily fluids for a relatively short period—for example, 24 hours in saliva, 48 hours in urine and 24 hours in blood. Additionally, technical limitations such as variations in drug metabolites and the sensitivity of qualitative detection methods allow some drug abusers to evade inspections and law enforcement by temporarily ceasing drug use selectively. In contrast, hair, as a statutory biological testing sample, has incomparable advantages.
Chuangxing's Model RDTD19H trace rapid hair drug detector is a quantitative and qualitative rapid detection and analysis instrument developed by Jinan Chuangxingweier Electronic Technology Co., Ltd. It can complete a single test within 10 minutes and detect substances such as methamphetamine, amphetamine, MDMA, ketamine, morphine, cocaine and cannabis in hair samples.
Q: Why can hair testing detect drug abuse? A: Dense capillaries surround hair follicles. Drugs or pharmaceutical substances present in the blood enter the scalp hair follicles during hair growth and are immobilized by the keratin in hair. Hair containing such substances grows above the scalp surface in approximately 3 to 5 days. As hair grows outward at a relatively constant rate, this mechanism allows for inference of the type, timing and dosage of drug abuse—this is the significance of "trace" detection.
Q: What are the applications and clinical significance of hair detection technology? A: Trace hair drug detection technology has unique advantages, including a long detection window, comprehensive information on drug abuse, as well as corruption-resistant, easy-to-collect, easy-to-preserve samples that allow for repeated sampling. Among these, the long detection window is the most prominent advantage: hair length can reflect drug use over several weeks to months, with a maximum detectable drug use history of 3 to 6 months. When combined with urine detection technology, it enables a comprehensive evaluation of a subject's drug abuse status, meeting the needs of anti-drug and drug rehabilitation work.
Hair testing technology for drug abuse has been recognized by the Society of Hair Testing (SOHT) and clearly specified in national standards including the Forensic Authentication Technical Specifications and the Provisions on Drug Testing Procedures . Laboratory test results of biological samples such as urine and hair are deemed expert evidence, serving as strong proof for identifying drug use behavior.
In addition, this instrument can distinguish between single-substance and polydrug abuse. It enables comprehensive diagnostic analysis in combination with clinical pathophysiological symptoms, achieving the goal of precise treatment for addicts.
