In Teviston, California, Accredited Drug Testing provides comprehensive hair follicle drug testing services. If a hair drug or alcohol test is what you require, Accredited Drug Testing has expertise in hair testing, and offers testing facilities nationwide capable of performing such tests. Typically, 1.5 to 2 inches of hair from the scalp or body can be used. Hair tests can detect drugs, alcohol/ETG, or other tailor-made options.
In the past few years, hair follicle drug tests have become more commonplace in drug testing methodologies. Many employers, judicial systems, and Substance Abuse professionals are demanding hair drug tests as opposed to the traditional urine tests. Hair follicle testing is favored by employers with zero-tolerance drug policies, courts, and probationary individuals. The main advantage of hair follicle drug tests is the extended detection time for drug usage, which usually spans up to 90 days, collected in a supervised setting, making cheating almost impossible. However, for detecting very recent drug use within 5 days, urine tests remain the 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 analysis is regarded as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substances through biomarkers trapped in the strands as they grow. When taken near the scalp, a sample can provide insight into alcohol and drug use for up to approximately three months. Hair collection is straightforward, hard to tamper with, and simple to transport.
A 1.5-inch sample containing roughly 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg, which is optimal for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advocated. It's advisable to use a jeweler’s scale for weighing the sample. Should scalp hair be inaccessible, a comparable quantity of body hair may be gathered. When mentioning head hair, we imply scalp hair solely. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The drug testing process in laboratories involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with the incorporation of a sample into the laboratory system. This phase ensures proper sealing and shipment of samples, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data input absent from an electronic chain of custody system.
Screening provides a preliminary test for drugs of abuse. Though it is a cost-effective means to rule out drug usage in most samples, a positive result requires subsequent confirmation for legal admissibility. Presumptive positives from Screening necessitate an additional verification.
Presumptive positives identified during Screening are further analyzed through Extraction by retrieving more hair from the original specimen. Drugs are isolated at lower concentrations in hair compared to other methods (e.g., urine or saliva), making hair screening the most challenging form of testing.
Confirmation occurs through GC/MS, GC/MS/MS, or LC/MS/MS for positive screens. All presumptive positive samples undergo washing before confirmation as necessary. The full laboratory procedure, from Accessioning to Confirmation, is overseen under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Often termed "hair follicle tests", the analysis itself targets the hair strand rather than the hair 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.
