In Duffield, Virginia, Accredited Drug Testing provides thorough hair follicle drug testing. If a hair drug or alcohol test is required, our expertise in hair testing and our extensive network of testing centers nationwide ensures availability. It generally requires 1.5 to 2 inches of hair from the head or body. Hair tests can be customized for drugs, alcohol/ETG, or other specific needs.
The preference for the hair follicle drug test has grown among drug testing methods recently. Employers, legal systems, and substance abuse experts often opt for hair testing over traditional urine tests. Hair follicle drug tests are favored by entities with zero-tolerance policies. Their main advantage is a longer detection window, usually up to 90 days, with reliable observation during collection, making them difficult to compromise. Nevertheless, recent drug use within 5 days is best evaluated with urine tests.

Hair testing is recognized as an effective method for identifying the use of drugs and alcohol. It retains biomarkers within the fibers of the hair strand as it grows, offering a prolonged account of substance usage. When taken from near the scalp, hair can relay up to a 3-month detection window for substances. It's easy to gather, challenging to taint, and simple to transport.
A sample measuring 1.5 inches with about 200 strands (comparable to a #2 pencil) nearest to the scalp yields 100mg of hair, which is ideal for testing and confirmation. For tests involving EtG, additional panels, and/or beyond 10 panels, it is advised to collect 150mg of hair. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair isn't an option, the equivalent quantity of body hair can be used. Head hair refers exclusively to scalp hair, while body hair encompasses other types (such as facial, axillary, etc.).
Process Overview
The drug testing laboratory process consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where the sample is entered into the laboratory system. This step includes checking that the sample was correctly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.
Screening conducts an initial rapid assessment for drugs of abuse. Although Screening is cost-effective and can rule out drug use in most cases, any positive result from Screening needs confirmation to be valid in legal scenarios. Samples with presumptive positive results during Screening need a second verification.
When a sample is presumptively positive in the Screening phase, more hair is extracted from the original specimen for the Extraction process. At this stage, drugs are pulled from hair at far lower concentrations than with other methodologies (e.g., urine or oral fluid), which makes hair drug testing the most challenging method to conduct.
Confirmation of positive results from Screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed to be positive get the required washing before confirmation. The full laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Limitations:
Note: While commonly called "hair follicle tests", the analysis actually involves the hair strand rather than the scalp's hair follicle.

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.
