Accredited Drug Testing provides comprehensive hair follicle drug assessments in Vesta, Virginia. If a drug or alcohol hair test is needed, Accredited Drug Testing specializes in these tests with centers nationwide. In most cases, 1.5 to 2 inches of crown or body hair is required. Hair assessments can reveal drug, alcohol/ETG usage, or other customized options.
In recent years, hair follicle drug assessments have become a more common method for drug detection. Many employers, courts, and substance abuse professionals favor hair over standard urine tests. Hair follicle assessments are ideal for organizations with strict no-drug policies, judicial systems, and probation participants. A primary advantage is a longer detection period, extending up to 90 days, with supervised sample collection making it nearly tamper-proof. For drug use within 5 days, urine tests remain most accurate.

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. By encapsulating biomarkers within the fibers of the growing strands, hair offers an extended record of substance use. When collected near the scalp, it can reveal about a 3-month usage period for both alcohol and drugs. Hair sampling is straightforward, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches with roughly 200 hair strands (approximately the thickness of a #2 pencil) near the scalp provides 100mg of hair, which is optimal for screening and confirming. For EtG, additional criteria, and/or tests exceeding 10 panels, a specimen of 150mg is advisable. We suggest using a jeweler’s scale to weigh the sample. In cases where scalp hair is not available, an equivalent quantity of body hair is acceptable. When we mention head hair, we specifically mean scalp hair, while body hair refers to all other types (facial, axillary, etc.).
Process Overview
The laboratory process for a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
In the Accessioning phase, the sample is initially processed into the laboratory’s system. This process involves confirming the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any needed data entry not covered by an electronic chain of custody system.
Screening serves as a preliminary check for substances of abuse. Although Screening is an economical method to dismiss drug use for most samples, any positive result must undergo confirmation to be permissible in legal proceedings. Any presumably positive Screening samples need a subsequent confirmation.
If a sample is presumed positive during the Screening phase, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are withdrawn from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex method to conduct.
GC/MS, GC/MS/MS, or LC/MS/MS techniques confirm any positive screening outcomes. All samples with presumptive positives are cleansed before confirmation as necessary. The full laboratory procedure, from Accessioning to Confirmation, is conducted under the CAP (College of American Pathologists) Hair designation and complies with the ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though commonly termed "hair follicle tests", the analysis is conducted on 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. 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.
