Accredited Drug Testing offers extensive hair follicle drug assessments in West Contra Costa, California. Our facilities are widespread across the nation, allowing easy access for hair drug and alcohol testing. For a typical hair test, at least 1.5 to 2 inches of hair is needed from the scalp area. Hair testing accommodates detection of various substances, including drugs and alcohol, with specialized options available.
The popularity of hair follicle drug testing has increased significantly recently. Organizations, legal entities, and addiction counselors increasingly prefer hair tests over traditional urine assessments. Hair follicle testing is favored by firms maintaining strict no-drug policies, judicial systems, and those under probation. Its key advantage is a far longer detection window for substance usage, typically covering up to 90 days, with an observed collection process, making it nearly impossible to tamper with. Yet, for identifying recent drug use within five days, urine tests remain the most accurate choice.

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.
Hair testing is now acknowledged as a robust method for identifying drug and alcohol consumption. This technique offers a lengthy record of alcohol and drug usage by embedding biomarkers within the strands of growing hair. When taken near the scalp, it offers a detection window of up to about three months for both alcohol and drugs. The collection process for hair is straightforward; it's somewhat resistant to tampering and is convenient to transport.
Obtaining a 1.5-inch sample of roughly 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp produces 100mg of hair, which is the optimal quantity for both screening and verification. For EtG, additional tests, and/or tests exceeding 10 panels, it's advisable to collect 150mg of the sample. We suggest measuring the sample with a jeweler’s scale. In the event scalp hair is not available, an equivalent quantity of body hair can be collected. When we reference head hair, it pertains solely to scalp hair. Body hair denotes all other types (facial, axillary, etc.).
Process Overview
There are four primary steps in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of integrating a sample into a lab’s system. This step verifies that the sample was correctly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data input not handled by an electronic chain of custody.
Screening is a preliminary rapid assessment for drugs of misuse. Although Screening is a cost-efficient way to rule out drug use in most samples, any positive screen needs to be validated to be admissible in a court setting. Any samples that return a presumptive positive result in Screening necessitate an additional confirmation.
Should a sample test presumptively positive in the Screening stage, additional hair is retrieved from the initial sample and readied for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute.
Positive screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptive positive are washed before confirmation as needed. Every step in the laboratory process from Accessioning to Confirmation is scrutinized according to both the CAP (College of American Pathologists) Hair designation and the accreditation of ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite often being called "hair follicle tests", the test targets 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.
