Accredited Drug Testing provides comprehensive hair follicle drug testing services in Tule Lake, CA. For those requiring a hair drug or alcohol screening, our expertise in hair testing is unmatched, offering nationwide centers ready to administer these tests. Typically, 1.5 to 2 inches of hair from the scalp or body is necessary for accurate results. Hair tests cover drugs, alcohol/ETG, along with other tailored options.
Recently, the inclination towards hair follicle drug testing as a preferred method has grown. Employers, court systems, and substance abuse professionals are increasingly favoring hair tests over traditional urine tests. This shift is due to the extended detection window of up to 90 days, conducted under supervision, virtually eliminating the possibility of tampering. However, for detecting recent drug use within a five-day span, urine tests remain the most precise choice.

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair holds a comprehensive history of alcohol and drug consumption by embedding biomarkers within the strands as they grow. Collecting hair near the scalp allows for a detection period of roughly three months for alcohol and drug use. Collecting hair is straightforward, relatively tamper-proof, and facile to transport.
A sample that is 1.5 inches long with approximately 200 hair pieces (comparable in width to a #2 pencil) from the scalp provides 100mg of hair, which is ideal for both assessment and verification. For EtG, additional tests, or tests exceeding 10 panels, it is suggested to have 150mg of the sample. It's advisable to measure the sample using a jeweler's balance. In the absence of scalp hair, a corresponding quantity of body hair can be taken. When mentioning head hair, it specifically means scalp hair. Body hair encompasses all other types of hair (such as facial, underarm, etc.).
Process Overview
The key stages in lab processing for a drug test outcome consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample's initial input into a lab's system. It includes confirming the sample's proper sealing and shipping, distributing a unique LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody protocol.
Screening conducts an initial rapid evaluation for drugs. Although Screening offers a cost-efficient solution for ruling out drug use on most samples, a positive screening result must be authenticated for legal acceptance. Samples showing presumptive positivity in Screening necessitate a secondary validation.
If a sample appears presumptively positive during Screening, additional hair is extracted from the starter sample and prepped for Extraction. This phase involves extracting chemicals from hair at a significantly reduced concentration relative to other methods (such as urine or saliva), highlighting why hair drug analysis is the most challenging methodology to execute.
Verification of a positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positive samples undergo washing in preparation for confirmation if required. The full lab procedure from Accessioning to Verification is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards certification.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests," the examination actually inspects 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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
