Hair follicle drug tests have become more prevalent in recent years as a preferred method for drug detection. Employment sectors, judicial systems, and addiction specialists increasingly opt for hair tests over traditional urine tests. These tests are favored by entities enforcing zero-tolerance drug policies due to their extended detection window, which spans up to 90 days, is collected under direct supervision, and resists tampering. Nonetheless, urine tests remain most precise for detecting recent drug use within a five-day period.

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 analyses have emerged as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged history of substance use by encasing biomarkers within its growing strands. When gathered near the scalp, hair can provide nearly a 3-month detection period for alcohol and drugs. Hair collection is straightforward, it's quite challenging to tamper with, and it's easy to transport.
A 1.5-inch section consisting of about 200 hair strands (around the thickness of a #2 pencil) closest to the head yields 100mg, the optimal amount for testing and confirmation. For EtG, additional testing, and/or examinations exceeding 10 panels, 150mg of the sample is advisable. Utilizing a jeweler’s scale to weigh the sample is recommended. In the absence of head hair, an equivalent quantity of body hair can be obtained. When discussing head hair, we refer exclusively to scalp hair. Body hair encompasses all other kinds such as facial and axillary hair.
Process Overview
The key phases in the laboratory assessment of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning manages the initial integration of a specimen into a lab system. This process checks that the sample was sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data entry that isn’t covered by an electronic custody chain.
Screening is a preliminary fast assessment for drugs of abuse. While Screening is cost-efficient for excluding drug use in most samples, a positive outcome requires a confirmation to be valid in legal settings. Any samples with preliminary positive results in Screening must undergo secondary confirmation.
For samples testing positive during the Screening phase, additional hair is separated from the original sample and prepared for Extraction. In this phase, drugs are extracted from hair at noticeably lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug analysis is considered one of the most intricate testing techniques.
Confirming any positive Screening outcomes is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation, if necessary. The entire lab process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation as well as adherence to ISO / IEC 17025 standards.

Note: While frequently termed "hair follicle tests", the assessment is conducted on the hair strand, not on the follicle beneath the scalp

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.
