Located in Twin Peaks, California, Accredited Drug Testing offers comprehensive hair follicle drug testing services. Whether it's hair drug or alcohol testing you need, our specialty is hair testing, with locations across the nation. Testing requires 1.5 to 2 inches of hair, either from the crown or body in many cases. Hair tests can detect drugs, alcohol/ETG, or be customized for other testing needs.
The use of hair follicle drug testing has become increasingly common in recent times. More employers, judicial systems, and substance abuse experts are opting for hair tests over traditional urine tests. This method is preferred by employers with zero-tolerance policies, court systems, and probation individuals. Unlike urine testing, hair tests offer a 90-day detection window, are collected under supervision, and are extremely difficult to tamper with. For detecting recent drug use in the last 5 days, urine tests still provide the most precise results.

Hair testing is increasingly viewed as an effective means of detecting drug and alcohol usage. Hair acts as a repository for long-term histories of alcohol and drug use by capturing biomarkers within the strands as they grow. Collected near the scalp, hair can offer an approximate detection period of three months for both alcohol and substances. Hair is straightforward to collect, relatively challenging to tamper with, and convenient to transport.
A 1.5-inch sample comprising approximately 200 hair strands (similar in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the preferred specimen for both screening and confirmation. For EtG, additional panels, and/or tests exceeding 10 panels, a 150mg specimen is advised. It's suggested to measure the specimen using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair can be gathered. References to head hair pertain solely to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The primary steps in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial introduction of a sample into a lab's system. This step ensures the sample was sealed and transported correctly, assigns a random Laboratory Accessioning Number (LAN), and completes any missing data entry not already filled in by an electronic chain of custody system.
Screening consists of a preliminary quick assessment for drugs of abuse. While it provides a cost-effective method to eliminate drug use in most samples, a positive screen must be confirmed for court admissibility. Any samples that test presumptively positive in Screening require a subsequent confirmation.
If a sample tests positive at the Screening stage, additional hair is extracted from the original specimen and readied for Extraction. During this phase, drugs are extracted from hair at much lower concentrations compared to other methods (such as urine or oral fluid), making hair drug testing the most intricate method to execute.
Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that test presumptively positive are washed before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though often called "hair follicle tests", the testing processes analyze 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
