Accredited Drug Testing offers comprehensive hair follicle drug testing services in Gilroy, California. For those needing a hair drug or alcohol test, Accredited Drug Testing specializes in hair testing and provides testing centers across all cities nationwide to conduct these tests. Typically, 1.5 to 2 inches of hair from the head's crown or the body is required. Hair tests can detect drugs, alcohol/ETG, or offer other tailored options.
Recently, hair follicle drug testing has become a more common method for conducting drug screenings. Employers, courts, and Substance Abuse professionals often choose this method over the traditional urine test. Hair follicle drug testing is favored by employers with zero-tolerance drug policies, court requirements, and probation terms. The key advantage of hair follicle testing is the extended detection period, which can reach up to 90 days. Additionally, the collection process is monitored, making it almost impossible to cheat. However, for detecting drug use in the preceding five days, the urine test remains the most accurate.

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair serves as a comprehensive record of alcohol and drug use by capturing biomarkers within the strands as they grow. When collected near the scalp, hair can offer roughly a three-month timeframe for detecting alcohol and drugs. Hair is easy to gather, relatively resistant to tampering, and straightforward to transport.
A 1.5-inch hair sample, consisting of approximately 200 strands closest to the scalp, will yield 100mg of hair, which is the optimal amount for preliminary and confirmatory tests. For EtG, additional analyses, or tests exceeding 10 panels, a specimen of 150mg is advisable. It is suggested to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, a comparable quantity of body hair can be collected. When mentioning head hair, it specifically refers to scalp hair. Body hair includes all other types of hair (e.g., facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result entails four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing phase of a sample within a laboratory’s system. This phase encompasses ensuring the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry not supplied by an electronic chain of custody system.
Screening involves an initial cursory examination for drugs of abuse. While Screening is a cost-efficient method to exclude drug usage in the majority of samples, any positive Screening must be validated for it to be legally admissible. Any samples that are presumptively positive during Screening necessitate a secondary confirmation.
Should a sample test presumptively positive in the Screening stage, more hair is extracted from the initial specimen and prepared for the Extraction phase. In this step, drugs are removed from hair at much lower concentrations than alternative methods (e.g., urine or oral fluid), which is why hair drug screening is the most complex method to execute.
Confirmation of any positive Screening outcome is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation when needed. The entire laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Note: Although frequently called "hair follicle tests", the test actually examines 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.
