Accredited Drug Testing provides comprehensive hair follicle drug assessments across Watsonville, California. Specializing in hair-based examinations, our centers, located in cities nationwide, facilitate these tests. Typically, 1.5 to 2 inches of scalp or body hair is required. Options for analyzing drugs, alcohol/ETG, or other tailored examinations are available.
In recent years, hair follicle testing has increasingly become part of drug testing practices. Many employers, the judiciary, and addiction specialists favor hair tests over traditional urine tests. This method is employed by zero-tolerance policy companies, legal systems, and probationary individuals. The primary advantage is an extended detection window of up to 90 days, with a monitored collection process that is tough to tamper with. Yet, for recent drug activity within 5 days, urine tests remain most effective.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair analysis is now regarded as a potent method for uncovering drug and alcohol usage. Hair retains a comprehensive history of alcohol and drugs by embedding biomarkers within the hair strand as it grows. If hair is gathered near the scalp, it can offer a roughly 3-month window for detecting alcohol and drugs. Collecting hair is straightforward, it's relatively hard to tamper with, and it's simple to dispatch.
A 1.5-inch section of around 200 hair strands (comparable to a #2 pencil's width) nearest to the scalp yields 100mg of hair, deemed the optimal amount for both screening and confirmation. For EtG, additional tests, or those above 10 panels, 150mg of the sample is suggested. It's advisable to weigh the sample with a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair can be collected. When discussing head hair, we mean only scalp hair. Body hair encompasses any other hair types (like facial, axillary, etc.).
Process Overview
The key stages in processing a drug test in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary processing of a sample into a lab’s system. This step ensures the sample was sealed and shipped correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary data entry lacking in an electronic chain of custody system.
Screening involves a preliminary rapid check for drugs. Despite being cost-effective for ruling out drugs in most samples, positive Screening results must be confirmed for court validity. Any samples that show positive markers in Screening require further confirmation.
In instances where Screening suggests a positive result, additional hair is obtained from the initial sample for Extraction. Drugs are extracted from hair at notably lower concentrations than with other methods (e.g., urine or oral fluid), making hair drug analysis particularly challenging.
Confirmation of positive screening results is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples marked as presumptive positives are cleansed before confirmation when necessary. The comprehensive lab procedure from start to finish is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 certification.
Advantages of hair drug testing:
Limitations:
Note: Though often termed "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the skin.

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.
