In Freedom, California, Accredited Drug Testing provides comprehensive hair follicle drug examinations. Specializing in hair and alcohol testing, they offer testing centers across the nation, including every city. Typically, 1.5 to 2 inches of hair from the scalp or body is sufficient. The hair samples enable detection of drugs, alcohol/ETG, and custom testing options.
Recently, hair follicle drug tests have become increasingly prevalent. A growing number of employers, courts, and Substance Abuse experts prefer these tests over urine tests. Businesses with stringent drug policies, courts, and probation officers utilize hair tests, benefiting from their 90-day detection range and observed collection process, thereby minimizing chances of sample tampering. However, urine tests remain more accurate for evaluating recent drug use within a five-day period.

Hair analysis is increasingly seen as an effective method for detecting drug and alcohol consumption. The hair captures long-term data of substances by embedding biomarkers within its strands. Collecting hair near the scalp can offer up to an estimated 3-month detection period for alcohol and drugs. The collection process for hair is straightforward, tampering is somewhat challenging, and it is convenient to ship.
A sample of approximately 1.5 inches consisting of about 200 hair strands (equivalent to the diameter of a #2 pencil) taken from close to the scalp will yield 100mg of hair, which is the optimal amount for conducting screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg is the recommended sample size. We advise weighing the sample with a jeweler’s scale. If scalp hair cannot be obtained, a comparable amount of body hair can be used. References to head hair denote only scalp hair, while body hair includes all other types (such as facial and axillary).
Process Overview
The drug test result processing in a laboratory involves Accessioning, Screening, Extraction, and Confirmation as the primary stages.
Accessioning is the first step where a sample is incorporated into a laboratory’s system. It entails confirming the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and inputting any additional data absent from an electronic chain of custody system.
During Screening, a preliminary rapid test is performed to check for drug abuse. Although Screening is a cost-efficient mode to eliminate drug usage in a majority of samples, a positive result must be corroborated for legal admissibility. Samples deemed presumptively positive during Screening mandate further confirmation.
When a sample indicates a presumptive positive at the Screening level, additional hair from the original sample is set aside for Extraction. This phase involves retrieving drugs from hair at much lower concentrations than found in other methods like urine or oral fluid, establishing hair drug testing as the most complex methodology.
Confirmation of any positive Screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positive results undergo washing before confirmation when necessary. The entire procedure from Accessioning to Confirmation is scrutinized under the guidance of both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Note: Frequently referred to as "hair follicle tests", the examination is actually 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.
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.
