Accredited Drug Testing offers comprehensive hair follicle drug evaluations in Ross Valley, California. For hair-based drug or alcohol assessments, Accredited Drug Testing excels in this domain, ensuring our centers nationwide are equipped for hair-based evaluations. Typically, 1.5 to 2 inches of head or body hair is sufficient. Hair tests can identify drugs, alcohol/ETG, or other tailored options.
In recent times, drug testing approaches increasingly incorporate hair follicle analysis. Various employers, judicial systems, and Substance Abuse specialists mandate hair drug tests over traditional urine tests. Hair follicle tests are favored by employers with stringent drug policies, judicial authorities, and probation officers. The major advantage lies in its extended detection window of up to 90 days, conducted with observed collection, rendering cheating almost impossible. For recent drug use within 5 days, urine tests remain the gold standard.

Hair analysis is now recognized as an effective method for identifying substance and alcohol usage. It provides a long-term record of alcohol and other substances by embedding biomarkers within the hair's growing strands. When gathered near the scalp, hair can reveal up to a three-month history for detecting alcohol and other substances. The collection process is straightforward, the sample is relatively tamper-proof, and it is easy to transport.
A 1.5-inch section of roughly 200 hairs (approximately the thickness of a #2 pencil) taken nearest to the scalp yields 100mg, which is ideal for both initial screening and validation. For EtG, additional tests, or tests exceeding 10 panels, a 150mg sample is preferred. It's advised to measure the specimen using a precision scale. If head hair is unattainable, an equivalent volume of body hair can be used. Head hair refers exclusively to scalp hair, whereas body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The key processes in lab analysis of drug test samples include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary preparation of a sample within a lab's system. This step ensures the sample is properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data recording not covered by an electronic chain of custody.
Screening is an initial swift check for substance abuse. Although cost-efficient for eliminating drug use in most samples, a positive result in Screening must be validated to be accepted legally. Any presumptive positive samples during Screening need a further confirmation.
If a sample tests presumptively positive during Screening, an additional hair portion is retrieved from the original sample and prepped for Extraction. Here, substances are isolated from hair at much lower concentrations versus other techniques (e.g., urine or oral samples), making hair drug testing a challenging procedure.
Confirmation of positive Screening outcomes is conducted using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples presumed positive must undergo a cleansing process prior to confirmation. The complete lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation 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.
