Accredited Drug Testing provides comprehensive hair follicle drug testing services in Ontario, California. Accredited Drug Testing excels in hair testing and offers testing centers throughout the country that can conduct a hair test, whether for drug or alcohol detection. Generally, 1.5 to 2 inches of hair from the head or body is sufficient, allowing analysis for drugs, alcohol/ETG, or other tailored testing options.
Recently, the approach to drug screening has increasingly favored hair follicle drug tests. A growing number of employers, legal authorities, and Substance Abuse professionals opt for these over traditional urine tests. Hair follicle drug tests are favored by organizations with strict anti-drug policies, as well as courts and individuals on probation. Their key advantage lies in detecting drug use for up to 90 days, under a monitored collection, making deception nearly impossible. While for identifying recent drug use within 5 days, urine tests remain accurate.

Hair analysis is increasingly recognized as a significant means for detecting substance use. Unlike other methods, hair captures a long-standing record of alcohol and drug use by embedding biomarkers within the fibers of its growing strands. When a sample is taken near the scalp, it can provide a detection period of up to three months for substances. Collecting hair is straightforward, it's relatively resistant to tampering, and can be easily mailed.
A sample size of 1.5 inches consisting of approximately 200 hair strands (comparable to a #2 pencil's thickness) closest to the scalp yields 100mg of hair, which is optimal for screening and verification. For tests involving EtG, add-ons, or more than 10 panels, a 150mg hair specimen is suggested. It's advisable to weigh the sample with a jeweler’s scale. If scalp hair isn't accessible, an equivalent quantity of body hair can be utilized. References to head hair pertain specifically to scalp hair, while body hair encompasses all other types (like facial or axillary hair).
Process Overview
The laboratory processing of drug test results includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into the laboratory's system. This consists of ensuring the sample was properly sealed and transported, generating a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent in an electronic chain of custody arrangement.
Screening serves as an initial rapid assessment for substances of abuse. Although Screening is a cost-effective strategy to exclude drug use in most samples, a confirmed positive is essential for legal admissibility. Samples appearing presumptively positive during Screening mandate further confirmation.
In cases where Screening results are presumptively positive, additional hair is selected from the initial sample and prepared for Extraction. This phase involves extracting drugs at notably lower concentrations from the hair compared to other methodologies (e.g., urine or oral fluid), which is why conducting hair drug screening is particularly challenging.
Confirmation for any positive Screening result is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing as necessary. The entire laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation as well as accreditation in accordance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests", the analysis is conducted on the hair strand itself, 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. 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.
