In Soledad, California, Accredited Drug Testing offers comprehensive hair follicle testing services. Specializing in both drug and alcohol hair tests, our centers are located across all U.S. cities. It's essential to have 1.5 to 2 inches of hair, taken from the head or body for testing. These analyses include screenings for drugs, alcohol/ETG, and other tailored options.
Over the last few years, hair follicle drug testing has become a more prevalent method. Employers, judicial systems, and substance abuse professionals often prefer this over traditional urine tests. This method serves employers with strict no-drug policies, and is also used by courts or probationary supervision. One major advantage is its extended detection timeframe, up to 90 days, making it hard to manipulate. Yet, for identifying recent drug use in the last 5 days, urine tests remain the most precise.

Hair analysis is regarded as a potent method for discovering substance and alcohol consumption. Hair captures long-term markers of alcohol and other substances by embedding biomarkers within the strands. When collected near the scalp, hair offers up to roughly a 3-month detection period for alcohol and other substances. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch segment of roughly 200 hair strands (about the girth of a #2 pencil) nearest to the scalp offers 100mg of hair, the optimum sample for testing and validation. For EtG, extensions, and/or tests exceeding 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is unavailable, an equivalent amount of body hair can be used. When discussing head hair, we are referring solely to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing of a specimen into a lab’s system. This encompasses verifying the specimen was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not provided by an electronic chain of custody system.
Screening is an initial rapid check for substances of abuse. While Screening is a cost-effective method to exclude substance use on most samples, a positive screen needs confirmation to be valid for legal proceedings. Any samples that are tentatively positive during Screening require a secondary affirmation.
If a sample tests tentatively positive at the Screening stage, additional hair is taken from the initial sample to prepare for Extraction. In this phase, drugs are extracted from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to conduct.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation if necessary. The entire laboratory procedure from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often called "hair follicle tests", the analysis is conducted on 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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
