Accredited Drug Testing offers comprehensive hair follicle drug testing in Carroll Valley, Pennsylvania. For those requiring a hair drug or alcohol examination, we excel in hair testing with facilities available in every city across the U.S. A minimum of 1.5 to 2 inches of hair is needed from the crown or body. Hair tests can identify drugs, alcohol/ETG, or other tailored testing criteria.
Lately, hair follicle tests have increasingly been incorporated into drug screening routines. Many employers, courts, and Substance Abuse therapists now prefer hair tests over standard urine assessments. These tests support organizations with zero-tolerance policies, judicial systems, and probationers. Their key advantage is a longer detection span, reaching up to 90 days, ensuring an observed collection process and making deception nearly impossible. Nevertheless, urine analysis remains most reliable for spotting drug use within the past five days.

Hair testing is now a recognized method for identifying drug and alcohol consumption. Hair offers a comprehensive history of alcohol and drug usage by encapsulating biomarkers within the strands as they grow. When taken close to the scalp, hair can offer up to a 3-month detection period for alcohol and drugs. Hair is easy to gather, hard to tamper with, and straightforward to transport.
A 1.5-inch sample consisting of about 200 hair strands (akin to the thickness of a #2 pencil) nearest the scalp yields approximately 100mg, which is the optimal sample for both screening and confirmation. For EtG, supplementary tests, and tests beyond 10 panels, 150mg of hair is advised. The specimen should ideally be weighed using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be used. In our context, head hair means scalp hair exclusively, while body hair encompasses all other types of hair (such as facial and axillary).
Process Overview
The laboratory processing of a drug test result consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary stage where a sample is processed into the lab’s system. This stage involves checking that the sample is sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and entering any additional data not covered by an electronic chain of custody.
Screening acts as the first swift evaluation for substances of abuse. Though it serves as a cost-efficient method for dismissing drug use in most samples, a positive screening result will need confirmation to be valid in legal settings. Samples exhibiting presumptive positive outcomes in Screening must undergo a secondary confirmation.
Should a sample test presumptive positive during the Screening stage, more hair is extracted from the original specimen for the Extraction process. In this stage, substances are derived from hair at markedly lower concentrations compared to other methods (e.g. urine or oral fluid), making hair drug screening one of the most challenging techniques to implement.
Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples suggestive of positive results undergo washing before confirmation if necessary. The entire lab process from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation as well as meeting ISO / IEC 17025 standards.

Limitations:
Note: Although commonly called "hair follicle tests", the examination actually analyzes hair strands, not the follicles 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.
