In West Sierra, California, Accredited Drug Testing provides comprehensive hair follicle drug testing. If you're seeking a hair drug or alcohol evaluation, we specialize in hair testing with centers available in all cities across the nation to administer these tests. A hair test requires 1.5 to 2 inches of hair, which can be sourced from your head or body, for drugs, alcohol/ETG, or other tailored testing.
Recently, hair follicle drug tests are increasingly favored for drug testing. Various employers, courts, and substance abuse experts demand hair tests over traditional urine tests. Employers enforcing zero-tolerance policies, judicial systems, and probation clients find these tests beneficial due to their extended drug detection period, up to 90 days, and collection in supervised settings. Despite this, for drug detection within recent 5 days, urine tests remain the reliable option.

Hair tests have become recognized as an effective method for detecting substance use. Hair captures a comprehensive history of alcohol and drug usage by embedding indicators within the strands as they grow. When taken near the scalp, hair can offer approximately a three-month detection period for substances. The collection process is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (similar in diameter to a #2 pencil) near the scalp provides about 100mg, which is the optimal amount for testing. For EtG, additional tests, or analyses beyond 10 panels, a 150mg specimen is advised. We suggest weighing the sample on a jeweler's scale. If scalp hair is inaccessible, a comparable quantity of body hair is an alternative. When mentioning head hair, it specifically means scalp hair. Body hair encompasses other types such as facial or axillary hair.
Process Overview
The process of analyzing a drug test consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into the lab’s system. This phase involves checking the integrity of the sealed and shipped sample, allocating a random LAN (Laboratory Accessioning Number), and completing any missing data entry not supplied by an electronic chain of custody system.
Screening acts as a preliminary examination for substances of abuse. Although screening is an economical way to dismiss drug presence in most samples, a positive finding must be verified to be valid in legal scenarios. Samples yielding presumptive positives during Screening require further verification.
In cases of a presumptive positive result in the Screening stage, additional hair is isolated from the initial sample and prepared for Extraction. During this stage, substances are extracted at much lower concentrations compared to other methods (e.g., urine or saliva), making hair drug testing a highly complex methodology.
Any positive screening results proceed to Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed prior to confirmation, as needed. The full laboratory workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair protocols and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests," the analysis examines 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. 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.
