Accredited Drug Testing offers comprehensive hair follicle drug testing services in Alexandria, Virginia. Whether you're in need of a drug or alcohol test, our expertise in hair testing extends nationwide with centers available in every city that can conduct these tests. Typically, 1.5 to 2 inches of hair from the crown or body is required for testing, which can detect drugs, alcohol/ETG, or be tailored for specific needs.
Recently, hair follicle drug tests have become a more common component of testing procedures. Employers, judicial systems, and substance abuse experts are increasingly opting for hair tests over urine tests. Hair tests are favored by employers for their zero-tolerance policies, as well as courts and probation officers, due to their extended detection period of up to 90 days, secure collection process, and resistance to tampering. However, urine tests remain preferred for determining recent drug use within the last five days.

Hair testing has emerged as a potent method for identifying drug and alcohol consumption. Hair acts as a record for long-term alcohol and drug use by capturing biomarkers within the fibers of the growing hair shaft. When taken near the scalp, hair can offer up to about a 3-month detection period for alcohol and drugs. Hair is easy to gather, somewhat tough to tamper with, and straightforward to transport.
A 1.5-inch sample of approximately 200 hair strands (around the width of a #2 pencil) nearest to the scalp will provide 100mg of hair, the ideal amount for both screening and confirmation. For EtG, additional tests, and/or panels above 10, a 150mg specimen is advised. It is suggested to measure the specimen on a jeweler’s scale. If scalp hair cannot be used, a similar amount of body hair may be collected. When discussing head hair, we mean scalp hair only. Body hair pertains to all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing of a sample into a lab’s system. This incorporates confirming that the sample was sealed and shipped correctly, generating a random LAN (Laboratory Accessioning Number), and completing any missing data entry not managed by an electronic chain of custody system.
Screening comprises an initial quick assessment for drugs of abuse. While Screening is an economical way to rule out drug usage in most samples, a positive screen must be confirmed for legal admissibility. Any samples with a presumptive positive in Screening need a further confirmation step.
If a sample exhibits a presumptive positive in the Screening stage, additional hair is retrieved from the original specimen and prepped for Extraction. In this stage, drugs are separated from hair at much lower levels than in other methods (e.g., urine or oral fluid), which is why hair drug screening is considered the most complex methodology to execute.
Confirmation of any positive screening result is completed through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are washed before confirmation when necessary. The entire lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the 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.
