Accredited Drug Testing provides comprehensive hair follicle drug assessments in Lakeport, California. If a hair-based drug or alcohol test is required, we excel in hair testing and offer locations nationwide, including all cities, for hair tests. Generally, 1.5 to 2 inches of hair from the scalp or body is required. These tests can detect drugs, alcohol/ETG, or customized testing options.
Recently, the hair follicle drug test has become a favored method for conducting drug assessments. Numerous employers, judicial systems, and Substance Abuse experts now require hair drug testing instead of the traditional urine analysis. Hair tests are preferred by employers with zero-tolerance drug policies, the courts, and probationary services. The primary advantage is the extended detection window for drug usage, often up to 90 days, conducted under observation, and hard to manipulate. Nonetheless, for checking drug use within the past 5 days, urine testing remains the most accurate.

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.
Viewed as a potent method for identifying drug and alcohol consumption, hair testing uses the hair strand's fibers to capture drug and alcohol biomarkers, offering an extended overview. When collected near the scalp, hair can indicate drug and alcohol use over roughly a three-month period. The collection process is straightforward, challenging to tamper with, and facilitates easy shipping.
Gathering a 1.5-inch sample, roughly 200 strands (similar to a #2 pencil's thickness), closest to the scalp yields 100mg, which is the perfect amount for analysis and confirmation. For EtG, add-ons, and tests exceeding 10 panels, a sample size of 150mg is advisable. It's suggested to measure the sample with a jeweler's scale. In cases where scalp hair isn't accessible, a comparable quantity of body hair might be used. References to head hair pertain solely to scalp hair. Body hair encompasses other types like facial and axillary hair.
Process Overview
The procedure for processing a drug test result in the laboratory includes four key steps: Accessioning, Screening, Extraction, and Confirmation.
In the Accessioning phase, a sample is initially processed into the laboratory system, ensuring the sample seal and shipping were proper, assigning a unique LAN (Laboratory Accessioning Number), and completing additional data entry not supplied by an electronic chain of custody system.
In the Screening stage, a quick preliminary check detects substance misuse. Though Screening is a budget-friendly method to exclude drug usage in most samples, a positive result requires further confirmation for legal acceptability. Any samples that indicate a potential positive in Screening need secondary verification.
Should a sample show a potential positive during the Screening phase, more hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are extracted at remarkably lower concentrations than other methods (e.g., urine or oral fluid), which renders hair drug testing as the most challenging to conduct.
Confirmation of any positive screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Every sample that tests presumptively positive is cleansed before confirmation, as necessary. The entire laboratory process, ranging from Accessioning to Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards compliance.
Advantages of hair drug testing:
Limitations:
Note: Although occasionally termed "hair follicle tests", the analysis is conducted on the hair strand and not on the follicle beneath the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.
