In Sonora, California, Accredited Drug Testing offers comprehensive hair follicle drug screening. Whether you require a drug or alcohol assessment, our expertise in hair testing is unmatched, with facilities available across all cities in the nation. Typically, 1.5 to 2 inches of hair is needed from the crown or body. These tests can detect drugs, alcohol/ETG, and offer other tailored options.
The hair follicle method has become a preferred choice for drug testing in recent years. Employers, legal systems, and substance abuse experts increasingly opt for hair tests over traditional urine tests. Companies with strict anti-drug policies, courts, and probation situations frequently utilize these assessments. The chief advantage is their ability to detect drug usage over a 90-day span, making them nearly foolproof, although urine tests remain best for detecting recent use within five days.

Hair testing is recognized as an effective technique for identifying drug and alcohol usage. Hair retains a prolonged record of alcohol and drug intake by capturing biomarkers within the strands' fibers as they grow. A sample sourced near the scalp can offer a detection span of about three months for alcohol and other drugs. Hair collection is straightforward, somewhat resistant to tampering, and convenient to send.
A 1.5-inch sample of roughly 200 hair strands, equivalent to the size of a #2 pencil, close to the scalp provides 100mg, the optimal amount for screening and verification. For EtG, add-ons, and tests exceeding 10 panels, a 150mg specimen is advisable. It's suggested to use a jeweler’s scale to measure the specimen. If scalp hair is not available, a comparable amount of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses other hair types such as facial or axillary.
Process Overview
The lab processing of a drug test outcome comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is introduced to the lab's system by confirming proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any additional data tasks not managed by an electronic chain of custody system.
Screening conducts a preliminary assessment for drugs of abuse. Though Screening is an economical method to exclude drug usage in most samples, a positive result needs verification to stand in court. Samples presumed positive in Screening need a follow-up confirmation.
If Screening indicates a possible positive, extra hair is extracted from the original specimen for the Extraction phase. Drugs are isolated from hair in much lower concentrations compared to other techniques (e.g., urine or oral fluid), which makes hair drug screening particularly arduous.
Any positive Screening result is confirmed through GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing before the confirmation step as required. The entire lab process, from Accessioning to Confirmation, is examined under the CAP (College of American Pathologists) Hair guidelines and accredited to ISO / IEC 17025 standards.

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.
