For those requiring tests for drugs or alcohol, Accredited Drug Testing excels in hair analyses with designations across cities nationwide ready to administer tests. Typically, 1.5 to 2 inches of head or body hair suffice for our analyses. Hair testing can assess for drugs, alcohol/ETG, or be customized further.
In recent developments, hair follicle drug tests have gained preference over traditional methods. Numerous employers, judicial bodies, and Addiction Specialists now mandate hair over urine tests. Employers adhering to zero-tolerance principles, judiciary requirements, and probation stipulations increasingly rely on hair follicle tests. Its prime advantage is an extended detection span of up to 90 days, under supervised collection, making deception nearly impossible. However, urine tests remain most accurate for instances within 5 days of use.

Hair testing is increasingly acknowledged as a robust method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug intake by embedding biomarkers within the strands of developing hair. When harvested near the scalp, hair can reveal a detection period of up to around three months for alcohol and drugs. Hair collection is straightforward, less prone to tampering, and easily transportable.
A 1.5-inch portion comprising roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, or those exceeding 10 panels, a sample of 150mg is advisable. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair cannot be obtained, a similar amount of body hair may be used. "Head hair" refers specifically to scalp hair, while "body hair" includes other types (facial, axillary, etc.).
Process Overview
The laboratory process for determining drug test results encompasses four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial integration of a sample into a laboratory's framework, including verifying the sample's proper sealing and shipment, assigning it a unique random LAN (Laboratory Accessioning Number), and completing additional data not covered by an electronic chain of custody system.
Screening involves an initial swift evaluation for substance abuse. While Screening efficiently rules out drug use in most samples, a positive result must be confirmed for court validity. Presumptively positive samples in Screening necessitate a secondary confirmation.
Should a sample appear positive from Screening, more hair is extracted from the original specimen for the Extraction phase. Here, drugs are isolated from hair at substantially lower concentrations than other methodologies (e.g., urine or oral fluid), making hair drug screening one of the most intricate techniques to execute.
Verification of any positive Screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples presuming positivity undergo pre-confirmation washing as appropriate. The entire lab procedure from Accessioning to Confirmation undergoes review following both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.

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.
