Accredited Drug Testing offers comprehensive hair follicle drug testing services in Hornbrook, California. If you need a hair drug or alcohol test, our expertise in hair testing ensures accurate results, with facilities available in all cities Nationwide to conduct the test. For most cases, at least 1.5 to 2 inches of hair from the crown or body is needed. Hair tests can assess drugs, alcohol/ETG, or other personalized testing options.
Over recent years, drug testing methods have increasingly adopted hair follicle testing. Employers, judicial systems, and Substance Abuse professionals often favor hair drug tests over the traditional urine tests. Employers with zero-tolerance policies, courts, and probationers rely on hair follicle testing for its longer detection span, typically covering up to 90 days, through a monitored process—making it tough to tamper with. Yet, for substance use within five days, urine tests remain most precise.

Hair analysis is now acknowledged as an effective means for identifying drug and alcohol consumption. Hair acts as a chronic reservoir of alcohol and drugs by capturing biomarkers within the strands of growing hair. Collected near the scalp, it offers a detection range of about three months for substances. It is easy to gather, resistant to tampering, and straightforward to transport.
A 1.5-inch section of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for screening and confirmation. For EtG supplements, and/or tests beyond the ten-panel standard, it is suggested to use 150mg of the sample. We advise assessing the sample on a jeweler’s scale. If scalp hair isn't available, the same quantity of body hair may be used. When mentioning head hair, we specifically mean scalp hair. Body hair refers to any other hair sources (facial, axillary, etc.).
Process Overview
The primary steps within the lab analysis of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial intake of a sample into a lab’s framework. This includes verifying the sample's sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not supplied via an electronic chain of custody system.
Screening conducts a preliminary evaluation for drugs of misuse. Although it serves as a cost-effective means to dismiss drug use in the majority of samples, a positive screening requires confirmation for court acceptance. Samples presumed positive in Screening necessitate secondary confirmation.
If a sample tests as presumptively positive in Screening, additional hair is extracted from the original sample and prepared for Extraction. Drugs are retrieved from hair at concentrations significantly lower than in other methodologies (such as urine or oral fluid), which is why hair drug screening is one of the most challenging methods to perform.
Confirmation of any positive screening results is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation, as necessary. The complete lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Note: Often termed "hair follicle tests", the test 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.
