In Pine Grove, California, Accredited Drug Testing offers comprehensive hair follicle drug testing services. Our expertise in hair testing extends across all our centers nationwide. A hair length of 1.5 to 2 inches is essential for testing, though body hair can also be used. From drugs and alcohol/ETG to other options, we provide tailored hair test analyses.
Recently, the preference for hair follicle drug tests over traditional methods has risen. Required by employers, courts, and Substance Abuse professionals, these tests counter standard urine analyses. Such tests suit zero-tolerance employers, courts, and probation situations. Key advantages include a longer drug detection period—up to 90 days—and an observed, hard-to-tamper collection process. However, urine tests remain the go-to for recent drug use detection within five days.

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 testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a history of alcohol and other drugs by embedding biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair can present up to a roughly 3-month detection duration for alcohol and other drugs. Hair collection is straightforward, somewhat resistant to adulteration, and convenient to transport.
A 1.5-inch section consisting of around 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional testing, and/or analyses exceeding 10 panels, a 150mg specimen is suggested. It is advisable to weigh the sample using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent amount of body hair can be collected. "Head hair" specifically refers to scalp hair only, whereas "body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
There are four primary stages in the lab processing of a drug test sample: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the foundational processing of a sample within a lab's framework. This step involves ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and filling out any additional data entry not encompassed by an electronic chain of custody system.
Screening serves as an initial rapid assessment for drugs of misuse. While Screening is an economical method to eliminate drug usage in most samples, a positive screen necessitates confirmation for court admissibility. Samples that test presumptively positive in Screening require further confirmation.
If a sample tests as potentially positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. Here, drugs are drawn from hair in lower concentrations compared to other methods (e.g., urine or oral fluid), explaining why hair drug screening is the most intricate methodology to apply.
Positive screening results are verified via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed to be positive are washed as necessary before confirmation. The complete lab process from Accessioning to Confirmation undergoes review per both the CAP (College of American Pathologists) Hair guidelines and accreditation to ISO / IEC 17025 standards.

Note: Although commonly termed as "hair follicle tests", the actual analysis focuses on the hair strand and 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.
