Accredited Drug Testing offers comprehensive hair follicle testing in Parkfield, CA. For individuals requiring drug or alcohol assessments via hair samples, Accredited Drug Testing excels in this area with centers available nationwide. Typically, it requires 1.5 to 2 inches of hair, though body hair can also be used. The tests encompass drugs, alcohol/ETG, and other tailored testing needs.
Over the past few years, the trend has shifted toward hair follicle testing as the preferred method for drug screening. Employers, courts, and substance misuse professionals now favor hair tests over traditional urine tests due to their effectiveness. These tests are ideal for zero-tolerance workplaces, the legal system, and probationary cases. Their major advantage lies in a prolonged detection window, up to 90 days, collected under direct supervision, making deceit nearly impossible. Nonetheless, for recent usage within five days, urine testing remains more precise.

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 now recognized as an effective method for identifying drug and alcohol consumption. Hair carries a comprehensive record of alcohol and drug intake by holding onto biomarkers within the hair's growing fibers. When taken near the scalp, hair can offer a detection timeframe of nearly three months for both alcohol and drugs. Hair sampling is straightforward, relatively tamper-resistant, and convenient for shipping.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp, yields 100mg of hair, the preferred quantity for both screening and verification. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the specimen is advised. It is suggested to use a jeweler’s scale for weighing the sample. If scalp hair isn't accessible, a proportional quantity of body hair could be collected. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The four primary phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial sample processing within a lab's system. This phase ensures the sample was correctly sealed and shipped, a random LAN (Laboratory Accessioning Number) is given, and any additional information not input via an electronic chain of custody system is completed.
Screening consists of an initial rapid assessment for substance abuse. Despite Screening being an economical method to dismiss drug use in most samples, a positive screen must be verified to be court-acceptable. Samples that are presumably positive during Screening mandate a subsequent confirmation.
Should a sample indicate a presumptive positive in the Screening phase, further hair is obtained from the initial sample for Preparation for Extraction. During this step, drugs are isolated from the hair at much lower concentrations than alternative methods (e.g., urine or oral fluid), making hair drug analysis the most challenging methodology to execute.
Verification of any positive Screen outcomes occurs via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized according to both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 criteria.

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.
