Accredited Drug Testing offers comprehensive hair follicle drug screening services in Port Hueneme, California. If a hair drug or alcohol test is required, Accredited Drug Testing focuses on hair testing, available in cities Nationwide with centers ready to conduct hair analyses. With 1.5 to 2 inches of head or body hair typically needed, hair tests can evaluate drugs, alcohol/ETG, or other tailored hair testing configurations.
The recent trend in drug testing emphasizes using a hair follicle drug test more commonly. This testing method is increasingly mandated by employers, judicial systems, and Substance Abuse experts, favoring it over traditional urine tests. Hair follicle drug tests are chosen by organizations enforcing zero-tolerance drug policies, legal bodies, and probation subjects. They offer an important advantage with longer detection periods, reaching up to 90 days. Collected consistently through a direct process, these tests are nearly tamper-proof. For assessing recent drug use, within a 5-day window, urine tests remain optimal.

Hair testing has emerged as an effective method for spotting drug and alcohol usage. By capturing biomarkers in hair fibers, hair offers a lasting account of alcohol and drug intake. When clipped near the scalp, hair provides roughly a three-month window for detecting substances. The collection process is straightforward, it's quite resistant to tampering, and it can be shipped with ease.
A 1.5-inch segment of about 200 hair strands (similar to a #2 pencil’s girth) near the scalp gives 100mg of hair, which is the perfect amount for both screening and confirmation. For tests beyond 10 panels, EtG, or add-ons, 150mg of the sample is suggested. We suggest using a jeweler’s scale to weigh the sample. If scalp hair isn’t an option, an equivalent amount of body hair may be used. Specifically, head hair refers to scalp hair exclusively. Body hair includes other hair types (facial, axillary, and so on).
Process Overview
The lab processing for a drug test result encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about initially integrating a sample into a lab’s system. This entails checking the sample's seal and shipment, assigning it a random LAN (Laboratory Accessioning Number), and completing any missed data entry not covered by electronic documentation systems.
Screening is an initial rapid assessment for drugs. It's a cost-effective approach for excluding drug usage in the majority of cases; however, a positive result here necessitates confirmation for court validity. Presumptive positives during Screening require further confirmation.
Should a sample yield a presumptive positive during Screening, additional hair is taken from the original sample to ready it for Extraction. This phase involves extracting drugs from hair at far lower concentrations than those found in methods like urine or oral fluid, underscoring the complexity of hair drug screening.
Confirmation of any positive screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if needed. The entire laboratory workflow from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair guidelines and meets ISO / IEC 17025 accreditation standards.

Note: Although commonly termed as "hair follicle tests", this test actually examines the hair strand and not 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. 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.
