Recently, the preference for drug testing methods has leaned more towards hair follicle drug tests. Many employers, judicial systems, and Substance Abuse specialists are opting for hair drug tests over the traditional urine tests. Hair follicle drug tests are chosen by employers with strict no-drug-use rules, courts, and those on probation. The key advantage of a hair follicle drug test is its longer drug detection window of up to 90 days, collected under direct supervision, and is extremely difficult to tamper with. However, for drug usage detection in the past 5 days, urine tests remain the most reliable.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing is now recognized as an effective method for detecting alcohol and drug consumption. Hair retains a prolonged history of substances by capturing biomarkers in its fibers as it grows. When cut near the scalp, hair testing can offer up to a 3-month detection period for drugs and alcohol. It's easy to gather hair, somewhat resistant to tampering, and convenient to transport.
An ideal sample comprises a 1.5-inch piece from about 200 strands of hair (approximately pencil size) cut nearest to the scalp, equaling 100mg, fitting for screening and thorough analysis. For EtG, extra tests, and/or panels over 10, a 150mg sample is suggested. We advise using a jeweler’s scale for specimen weight verification. If scalp hair isn't available, collect a comparable amount of body hair. When mentioning head hair, we mean scalp hair alone, while body hair includes all other hair variations (facial, axillary, etc.).
Process Overview
The drug testing lab procedure encompasses four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample’s initial processing into the lab system. This includes ensuring the sample's sealing and correct shipment, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any additional data input not supplied by an electronic custody system.
Screening is an initial rapid assessment for substance abuse. While it's a budget-friendly method to discard most samples for drug usage, court-admissible samples need a confirmed positive screen. Any screening-positive samples require secondary confirmation.
Should a sample be positive in Screening, additional hair is taken from the first sample and prepped for Extraction. In this phase, substances are retrieved from hair at lesser concentrations compared to other methods (e.g., urine, saliva), which explains the complexity of hair drug screening.
Confirmation for any positive screening involves GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples needing a confirmation are washed as warranted. The lab's complete process from Accessioning to Confirmation gets a review under both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. 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.
