Accredited Drug Testing provides thorough hair follicle drug testing services in Dunnigan, California. For those requiring a hair or alcohol test, Accredited Drug Testing excels in hair testing with facilities nationwide. Typically, 1.5 to 2 inches of hair from the crown or body is necessary. Hair tests can determine drug use, alcohol/ETG levels, or other tailored testing options.
Over the past few years, hair follicle drug tests have become increasingly preferred for drug screening. Organizations, legal systems, and substance abuse experts now favor hair tests over traditional urine analysis. These tests are especially useful for employers enforcing strict drug policies, legal bodies, and probation officers. Hair follicle drug tests boast a significant advantage—a detection span of around 90 days, with a supervised collection that is tough to manipulate. Nevertheless, urine tests remain the most precise for identifying recent usage within 5 days.

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 regarded as a potent method for identifying drug and alcohol consumption. Hair captures a long-term timeline of alcohol and drug use by embedding biomarkers in the strands of hair in growth. When gathered closely to the scalp, hair can offer up to a 3-month detection span for alcohol and drugs. Hair is easy to gather, moderately hard to tamper with, and convenient to transport.
A sample length of 1.5 inches containing about 200 strands (around the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, ideal for screening and validation. For EtG, extras, and/or tests exceeding 10 panels, a specimen of 150mg is suggested. We advise using a jeweler's scale for weighing. If scalp hair isn't available, a proportionate amount of body hair may be utilized. Head hair denotes scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The primary stages in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample within a lab's system. It entails ensuring the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any missing data not present via an electronic chain of custody.
Screening encompasses a preliminary rapid assessment for substance abuse. While Screening is a cost-efficient method to exclude drug use in most cases, a positive screen requires validation to be legally admissible. Presumptive positives in Screening need a secondary verification.
For samples with presumptive positives in the Screening phase, additional hair is extracted from the original sample for Extraction. In this phase, drugs are retrieved from hair at significantly reduced concentrations than other methods (e.g., urine or saliva), making hair drug testing the most challenging methodology.
Verification of any positive screen result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before verification as necessary. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 certification.
Advantages of hair drug testing:
Limitations:
Note: Despite being called "hair follicle tests", the analysis examines the hair strand and not the follicle beneath the skin.

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.
