Accredited Drug Testing provides extensive hair follicle drug assessments in Fredericksburg, Pennsylvania. For anyone requiring a hair-based drug or alcohol screening, we are experts in this field with multiple testing sites across the nation and locally available. Generally, 1.5 to 2 inches of head or body hair is needed for the examination. These tests can detect drugs, alcohol/ETG, or be tailored for specific requirements.
Recently, hair follicle drug testing has gained popularity as a preferred method. This approach is now commonly mandated by employers, judicial systems, and addiction specialists, replacing traditional urine tests. Hair testing appeals to those enforcing strict no-drug-use policies due to its extended detection period, typically lasting up to 90 days. This method is supervised, making it nearly impossible to manipulate. Despite its advantages, urine tests remain optimal for identifying recent drug use within the last 5 days.

Hair testing is now regarded as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged history of substances by embedding biomarkers within the strands as they develop. When cut close to the scalp, hair can reveal drug and alcohol use over a period of up to roughly three months. Collection is straightforward, tampering is somewhat challenging, and shipping is convenient.
An ideal screening and confirmation sample consists of a 1.5-inch portion containing roughly 200 strands, akin to the thickness of a #2 pencil, and yields 100mg of hair. For EtG, additional tests, and any test exceeding 10 panels, 150mg is advisable. Using a jeweler’s scale for accuracy is suggested. Should scalp hair be unavailable, a similar quantity of body hair may be collected. "Head hair" pertains specifically to scalp hair, whereas "body hair" refers to all other kinds (such as facial and axillary).
Process Summary
The laboratory processing of a drug test result entails four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating the sample into a lab’s system. This step confirms that the sample remains sealed and properly transported, assigns a random LAN (Laboratory Accessioning Number), and completes any manual data entry not covered by an electronic chain of custody system.
Screening serves as an initial assessment for substance abuse. While economical and effective for ruling out drug presence in most cases, court-admissible results necessitate confirmation of any positive findings. Samples flagged as presumptively positive during screening require further confirmation.
If presumptive positivity is indicated in Screening, additional hair from the original sample is utilized for Extraction. This phase involves retrieving drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which explains the complexity of hair drug testing.
Positive results from Screening undergo confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed positive are cleansed before confirmation if necessary. The complete lab protocol from Accessioning to Confirmation is conducted under the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
Hair drug testing offers these benefits:
Challenges:

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.
