We provide testing facilities Nationwide, including every city, to conduct hair tests efficiently. Typically, hair lengths of 1.5 to 2 inches from the head or body are sufficient. The analysis can include drugs, alcohol/ETG, or other tailored options.
Recently, hair follicle drug tests have become more prevalent in substance evaluation. Employers, judicial systems, and Substance Abuse experts now prefer hair tests over traditional urine screenings. These tests are favored by entities enforcing zero-tolerance drug policies and by people on probation. The main advantage is their extended detection duration, up to 90 days, collected under supervision, and is remarkably tamper-proof. For recent drug use within 5 days, urine tests remain most accurate.

Hair testing is recognized as an effective method for identifying drug and alcohol use. Hair provides a comprehensive timeline of substance use by capturing biomarkers inside the developing hair fibers. If gathered near the scalp, hair can offer a detection range of up to three months for substances. It is easy to collect hair, difficult to tamper with, and simple to transport.
A 1.5-inch segment of around 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp produces 100mg of hair, an optimal amount for analysis. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advisable. We suggest using a jeweler's scale to ensure accuracy. If scalp hair is unavailable, a similar quantity of body hair may be obtained. When mentioning head hair, we refer specifically to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four essential phases in processing a drug test result in the lab consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary entry of a specimen into the lab’s system. This entails verifying the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and handling any supplementary data entry absent from an electronic chain of custody system.
Screening involves a preliminary evaluation for illegal substances. Although Screening is a cost-effective measure to exclude drug use in most samples, a positive screen must be validated to be court-admissible. Samples that are potentially positive in Screening necessitate additional confirmation.
If a sample tests potentially positive during Screening, additional hair is extracted from the initial sample and prepped for Extraction. In this phase, substances are drawn from hair at much lower concentrations than alternate methods (such as urine or oral fluid), which is why hair drug screening is the most complex technique to conduct.
Confirmation of any positive screening outcome is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All potentially positive samples undergo washing prior to confirmation when necessary. The complete lab process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although sometimes called "hair follicle tests", the examination targets the hair strand rather than the hair 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.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
