Accredited Drug Testing offers comprehensive hair follicle drug assessments in Lancaster, Virginia. For those requiring a hair drug or alcohol evaluation, we specialize in such tests, with facilities across the nation ready to handle them. Typically, 1.5 to 2 inches of hair on the head or body are necessary. Hair analyses can be customized for drugs, alcohol/ETG, and other specific testing needs.
Recently, employing hair follicle drug evaluation has become more prevalent in drug testing methods. Many employers, legal entities, and substance abuse professionals are opting for hair drug assessments over the common urine tests. Employers with strict drug-free policies, courts, and probation-supervised individuals often use these tests. A key advantage is the long drug detection window of up to 90 days, obtained during observed collection, making it hard to falsify results. Yet, for recent drug use within a 5-day window, urine tests remain the most accurate.

Hair testing is considered a robust method for identifying drug and alcohol use. The hair captures a prolonged record of alcohol and drug intake by embedding biomarkers within the growing hair strand's fibers. When cut close to the scalp, hair can reveal substance use for up to approximately 3 months. The collection of hair is straightforward, less prone to tampering, and simple to transport.
A 1.5-inch sample of roughly 200 hair strands (similar in size to a #2 pencil) near the scalp provides 100mg of hair, ideal for testing and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg of hair is advisable. We suggest using a jeweler's scale for weighing the hair sample. If hair from the scalp is unavailable, a similar amount of body hair can be used. "Head hair" refers specifically to scalp hair, whereas "body hair" includes all other hair types (like facial or axillary hair).
Process Overview
The core stages in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves introducing a sample into a laboratory’s system. This step includes inspecting that the sample was sealed and transported correctly, issuing a random LAN (Laboratory Accessioning Number), and performing any data entry missing from an electronic chain of custody system.
Screening is a preliminary rapid analysis for substances of abuse. While a cost-efficient method to eliminate drug use among most samples, a positive screen necessitates further confirmation to be valid in judicial scenarios. All samples with presumptive positive results in Screening require secondary verification.
If a sample is presumptive positive during Screening, additional hair is extracted from the original sample and readied for Extraction. During Extraction, drugs are extracted from hair at a much lower concentration than with other techniques (like urine or oral fluid), highlighting the complexity of hair drug testing.
Any positive results from screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are cleansed before confirmation as required. The entire testing procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and is compliant with ISO / IEC 17025 standards.

Limitations:
Note: Although commonly called "hair follicle tests", the test analyzes the hair strand rather than the follicle under 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. 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.
