Accredited Drug Testing offers comprehensive hair follicle drug testing to those in Willows, California. For individuals requiring drug or alcohol analysis, our expertise in hair testing extends across multiple cities nationwide, with numerous centers ready to conduct these tests. While hair from the head is typically used, body hair of 1.5 to 2 inches can suffice. Hair analysis can detect drugs, alcohol/ETG, or be tailored for other testing needs.
Over recent times, drug testing procedures have increasingly incorporated hair follicle tests. Engaged by employers, legal bodies, and Substance Abuse professionals, hair drug tests are preferred over conventional urine tests. Employers with rigid anti-drug policies, courts, and those overseeing probation benefit from hair follicle tests due to their extended detection window of up to 90 days, with collection closely monitored to prevent tampering. However, for recent drug use within a five-day period, urine tests remain exceptionally accurate.

Hair testing is recognized as a significant tool for identifying drug and alcohol consumption. By trapping biomarkers in the fibers of actively growing hair strands, hair offers a prolonged historical record of alcohol and drug use. When taken near the scalp, hair can provide an approximate 3-month detection timeframe for alcohol and drug usage. Collecting hair is straightforward, tough to tamper with, and simple to transport.
A sample of 1.5 inches comprising roughly 200 hair strands (about the width of a #2 pencil) closest to the scalp gives 100mg of hair, which is the optimal quantity for screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is suggested. We advise weighing the sample using a jeweler’s scale. If scalp hair isn't available, an equivalent amount of body hair may be used. References to head hair mean only scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The primary steps involved in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into a lab's system by ensuring the sample is properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any needed data entry absent in an electronic chain of custody system.
Screening entails an initial rapid inspection for drugs of abuse. While Screening is a cost-effective method to rule out drug usage for most samples, a positive screen must be confirmed to be eligible for court use. Samples that are presumptive positive during Screening require subsequent confirmation.
If a sample shows a presumptive positive result in the Screening phase, additional hair is taken from the initial sample and readied for Extraction. Drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), which is why hair drug testing is the most complex method to conduct.
Confirmation of any positive screen result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptive positive samples are cleansed prior to confirmation if necessary. The entire lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
