At Accredited Drug Testing, we offer comprehensive hair follicle drug screening in Shaver Lake, California. If you're in need of a hair or alcohol test, our specialty in hair analysis is unmatched, with facilities nationwide. Typically, 1.5 to 2 inches of hair from the scalp or body is required. Our hair tests can be tailored for drugs, alcohol/ETG, or other specific purposes.
In the past few years, the preference for hair follicle drug testing over traditional methods has grown. Increasingly, employers, legal systems, and substance abuse counselors are opting for hair tests over the usual urine samples. Employers with strict anti-drug policies and courts often favor hair tests for their extended detection period—up to 90 days. While nearly cheating-proof and conducted under observation, urine tests are still preferred for recent drug use detection within the past 5 days.

Hair testing is recognized as a valuable method in identifying drug and alcohol consumption. It captures a long-term record of such substances by embedding biomarkers within the hair's fibers as it grows. When taken near the scalp, hair can reveal an alcohol and drug detection timeframe of up to roughly three months. It's easy to gather, relatively hard to tamper with, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil's thickness) closest to the scalp generates 100mg of hair, which is an optimal amount for testing and confirmation. For EtG, additional screens, and/or tests exceeding 10 panels, 150mg of hair is advised. Employ a jeweler's scale for weighing the sample. If scalp hair is absent, a comparable quantity of body hair can be utilized. References to head hair pertain solely to scalp hair. Body hair encompasses other hair types (facial, axillary, etc.).
Process Overview
The four critical stages in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary processing of a sample into the laboratory's system. This process confirms that the sample was securely sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data input not covered by an electronic chain of custody system.
Screening involves an initial rapid assessment for drug presence. While Screening is an economical approach to exclude drug usage in most samples, a positive result requires confirmation to be court-admissible. Samples that test presumptively positive during Screening necessitate further confirmation.
In the event of a presumptively positive result during Screening, additional hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are isolated from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), which explains why hair drug screening is more challenging to execute.
Confirmation of any positive Screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed prior to confirmation when necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and the accreditation 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.
