In Thermalito, California, Accredited Drug Testing provides comprehensive hair follicle drug testing. Specializing in such assessments, our centers are nationwide, ready to conduct hair tests. Hair on the crown measuring 1.5 to 2 inches—or elsewhere on the body—can be used. These tests can check for drugs, alcohol/ETG, or other tailored hair testing needs.
Recently, hair follicle drug testing has gained prominence in drug testing methods. Employers, courts, and substance abuse experts often favor it over traditional urine tests. This method is popular with zero-tolerance workplaces, legal systems, and probation monitoring, primarily due to its extended detection period, lasting up to 90 days, and the challenging nature of falsifying results. That said, for recent drug use within five days, urine tests remain the gold standard.

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 has emerged as an effective instrument for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug markers within the strands of the growing hair. When gathered near the scalp, hair can offer approximately a 3-month detection timeframe for both alcohol and drugs. Hair is easy to collect, challenging to tamper with, and straightforward to transport.
A 1.5-inch segment comprising about 200 hair strands (about the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample size for analysis and verification. For EtG, additional tests, and/or more than 10 panels, 150mg of hair is advised. We recommend using a jeweler’s scale to weigh the hair. If scalp hair isn't available, a similar quantity of body hair can be used. Head hair refers specifically to scalp hair. Body hair includes all other hair categories (facial, axillary, etc.).
Process Overview
The primary stages in the lab handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into a lab's database. This involves checking that the sample was sealed and delivered securely, assigning a random LAN (Laboratory Accessioning Number), and completing any leftover data entry absent from an electronic chain of custody system.
Screening involves an initial rapid assessment for drugs of abuse. Although Screening is an economical means to dismiss drug use in most samples, a positive result needs confirmation to be court-admissible. Any samples flagged as presumptively positive during Screening must undergo additional confirmation.
Should a sample be deemed presumptively positive in the Screening phase, more hair is taken from the original sample for Extraction. This phase involves extracting drugs from hair at a significantly reduced concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Confirmation of any positive screening finding is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as presumptive positive are cleaned before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation undergoes review per both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While often called "hair follicle tests", the test itself examines the hair strand rather than 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.
