Accredited Drug Testing provides comprehensive hair follicle drug screening services in South Chesconessex, Virginia. Specializing in hair drug tests, our centers are located nationwide. Require a hair or alcohol test? Typically, 1.5 to 2 inches of crown or body hair suffices. Hair tests can determine the presence of drugs, alcohol/ETG, or custom hair testing solutions.
The prevalence of hair follicle drug testing has surged recently. More employers, legal entities, and substance abuse experts prefer hair drug tests over traditional urine tests. They're ideal for organizations with zero-tolerance drug policies, legal settings, and probation scenarios. A major advantage is the prolonged detection period, usually up to 90 days, with observed sample collection, reducing tampering risk. Yet, for detection within 5 days, urine tests remain the gold standard.

Hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair offers a prolonged history of substance use by encapsulating biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair can present up to an estimated 3-month detection period for substances. Hair is straightforward to gather, somewhat challenging to tamper with, and simple to send.
A 1.5-inch piece containing about 200 hair strands (roughly the width of a #2 pencil) closest to the scalp yields 100mg of hair, the prime sample for both screening and confirmation. For EtG, additional checks, or tests exceeding 10 panels, 150mg of the hair specimen is suggested. It's advisable to measure the specimen using a jeweler’s scale. If scalp hair is lacking, an equivalent portion of body hair may be gathered. When discussing head hair, it pertains solely to scalp hair. Body hair includes all other hair kinds (facial, axillary, and so forth).
Process Overview
The primary phases involved in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary handling of a sample within a laboratory’s framework. This involves confirming that the sample was appropriately sealed and dispatched, allocating a unique LAN (Laboratory Accessioning Number), and completing any further data input absent from an electronic chain of custody mechanism.
Screening entails an initial rapid assessment for substances of abuse. Although Screening is a budget-friendly approach to exclude drug consumption in most cases, a positive screen needs validation to be permissible in legal contexts. Any samples tentatively positive in Screening necessitate a subsequent confirmation.
Should a sample yield a presumptively positive outcome during Screening, additional hair is extracted from the initial sample and gets ready for Extraction. Here, substances are extracted from hair at a notably lower concentration compared to other techniques (e.g., urine or oral fluid), thereby rendering hair drug testing as the toughest technique to conduct.
Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation as needed. The entire lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair specification and accredited by ISO / IEC 17025 standards.

Note: While often termed "hair follicle tests", the analysis primarily targets the hair strand and not the follicle beneath 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.
