Accredited Drug Testing provides comprehensive hair follicle drug tests in Hanford, California. For those in need of a hair or alcohol test, Accredited Drug Testing is an expert in hair analysis with testing locations nationwide. Typically, 1.5 to 2 inches of hair from the head or body is required. Hair tests can screen for drugs, alcohol/ETG, or other tailored testing options.
Recently, hair follicle drug testing has become a more common approach in drug testing protocols. Many workplaces, judicial systems, and substance abuse professionals now prefer hair tests over the standard urine tests. These tests are ideal for employers enforcing zero-tolerance drug policies, courts, and probation programs. The main advantage of hair testing is its extensive drug-use detection period of up to 90 days, with minimal chance of manipulation. However, urine tests remain the best method for detecting drug use within the last 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 analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair presents a lengthy record of consumption by capturing biomarkers within the hair's expanding fibers. Samples taken near the scalp can reveal up to a three-month tracking period for alcohol and other substances. Hair is straightforward to gather, somewhat resistant to tampering, and convenient to transport.
A strand segment of 1.5 inches consisting of roughly 200 hairs (comparable to a #2 pencil in thickness) adjacent to the scalp will provide 100mg of material, an optimal amount for testing and verification. For EtG, supplement tests, and analyses beyond ten panels, 150mg of the sample is suggested. We advise the use of a jeweler's scale for weighing the sample. If there's no scalp hair, a similar quantity of body hair can be collected. References to head hair pertain solely to scalp hair. Conversely, body hair encompasses other hair types (facial, axillary, etc.).
Process Overview
The lab processing of a drug test result encompasses four major phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the first-stage processing of a specimen into a laboratory framework. This process involves ensuring the sample was securely sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and handling any extra data input absent in an electronic chain of custody system.
Screening serves as an initial brief examination for substance abuse. Though cost-efficient for ruling out drug presence in most specimens, a positive screening necessitates confirmation for court admissibility. Samples showing presumptive positives in Screening require additional verification.
For samples presumed positive at the Screening step, further specimen is prepared for Extraction. Here, drugs are retrieved from hair at substantially lower concentrations than other methods (such as urine or oral fluid), underscoring hair testing as the most challenging technique to execute.
GC/MS, GC/MS/MS or LC/MS/MS techniques are utilized for Confirmation of any positive screening outcomes. All samples indicating presumptive positives undergo washing before confirmation as needed. The complete laboratory workflow from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 guidelines.
Advantages of hair drug testing:
Limitations:
Note: Commonly dubbed "hair follicle tests", the procedure evaluates the hair strand, not the 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. 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.
