Accredited Drug Testing provides comprehensive hair follicle drug screening services throughout East San Gabriel Valley, California. For those requiring a hair or alcohol test, our centers, conveniently located across all cities nationwide, specialize in hair testing. Typically, 1.5 to 2 inches of hair from the crown or other body areas is necessary. Our tests assess for drugs, alcohol/ETG, or can be tailored to specific needs.
In recent years, the approach to drug screening has increasingly incorporated hair follicle drug tests. Many employers, courts, and substance abuse professionals now prefer hair drug tests over traditional urine tests. Employers with zero-tolerance policies, judicial entities, and individuals on probation utilize these tests for their extended detection window of up to 90 days, the observed collection process, and their resistance to tampering. However, for detecting very recent drug use within the past five days, urine tests remain the most precise option.

Hair analysis is now widely regarded as an effective method for detecting substance usage, including drugs and alcohol. By capturing biomarkers within the fibers of the hair as it grows, hair offers an extended timeline of alcohol and drug history. When hair is clipped near the scalp, it can reveal up to a 3-month period for drug and alcohol detection. Hair is straightforward to gather, moderately resistant to tampering, and uncomplicated to transport.
A 1.5-inch hair segment consisting of around 200 strands (roughly akin to the thickness of a #2 pencil) near the scalp will yield 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, 150mg of hair specimen is advisable. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is unavailable, a similar volume of body hair can be retrieved. Note that when we refer to head hair, we specifically mean scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into the laboratory’s system. This phase includes verifying the sample's integrity in terms of sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and carrying out any additional data entry absent from an electronic chain of custody mechanism.
Screening constitutes an introductory rapid assessment for illicit substances. Despite being cost-effective for excluding drug use in most samples, a positive screen must face confirmation to be legally accepted. All samples that appear positive during Screening necessitate further confirmation testing.
In instances where Screening yields a presumptive positive outcome, additional hair is taken from the original sample for the Extraction stage. In this phase, drugs are isolated from hair at concentrations considerably lower compared to other methods (such as urine or oral fluid), which explains the complexity of hair drug screening.
Confirmation for any positive Screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples that tested presumptively positive are cleansed if required. The lab process from Accessioning to Confirmation undergoes thorough review in alignment with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

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.
