Specializing in hair tests for drugs and alcohol, we have nationwide testing centers for your convenience. Generally, 1.5 to 2 inches of hair is required, and this method can be adapted for custom testing needs, including ETG.
These days, hair follicle drug testing has gained popularity. Employers, courts, and substance abuse specialists prefer this over traditional urine tests for its reliability. Hair tests are ideal for zero-tolerance policies, offering a detection window of up to 90 days which reduces the likelihood of manipulation. However, urine tests are most accurate for drug use within the past five days.

Hair analysis has emerged as an effective method for detecting alcohol and drug use. It offers a comprehensive history of substance intake by capturing biomarkers within the fibers of the growing hair strand. When collected near the scalp, hair can provide a detection period of up to three months for alcohol and drugs. Hair collection is straightforward, hard to tamper with, and easy to transport.
A 1.5-inch sample containing roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp results in about 100mg, the optimal amount for both screening and confirmation processes. For EtG, add-ons, or tests exceeding 10 panels, 150mg is suggested. A jeweler's scale is recommended to weigh the sample. If scalp hair is not available, an equivalent amount of body hair can be used. "Head hair" pertains only to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).
Process Overview
Laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the preliminary processing of a sample into a laboratory's system. This step entails ensuring the sample's proper sealing and shipping, assigning a random Laboratory Accessioning Number (LAN), and completing any necessary data entry not provided by an electronic chain of custody system.
Screening provides a preliminary check for drugs of abuse. Though cost-efficient for eliminating drug use in most samples, a positive screen must be confirmed to be legally valid. Samples with a presumptive positive in Screening require a secondary confirmation.
When a sample is presumptive positive during Screening, additional hair is extracted from the initial sample for Extraction. In this phase, drugs are isolated from hair at much lower concentrations compared to other methods (such as urine or oral fluid), making hair drug analysis the most complex to execute.
Confirmation of any positive screen results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation as required. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Note: Although commonly referred to as "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
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.
