Accredited Drug Testing offers comprehensive hair follicle drug evaluations in Paxtonville, Pennsylvania. If a hair drug or alcohol test is necessary, Accredited Drug Testing excels in hair assessments and boasts centers across all cities Nationwide ready to administer a test. Typically, 1.5 to 2 inches of head or body hair is required. These tests scrutinize drugs, alcohol/ETG, or other tailored options.
Recently, drug evaluation methods have increasingly integrated hair follicle testing. This approach is favored by numerous employers, courts, and Substance Abuse experts over the traditional urine test. Hair follicle screening is employed by organizations with strict drug-use policies, judicial systems, and probation requirements. Its major advantage is a significantly prolonged detection span of drug use, generally up to 90 days, with supervised specimen collection, making tampering nearly impossible. Nevertheless, for detecting drug use within a 5-day window, urine testing remains the most precise.

Considered a robust approach for detecting drug and alcohol consumption, hair testing offers a comprehensive, extended insight into substance use by preserving biomarkers within the developing strands. The collection of hair near the scalp can reveal substance usage history for up to three months. The sampling process is straightforward, challenging to tamper with, and convenient for transport.
A 1.5-inch closest-to-scalp hair specimen, consisting of approximately 200 strands (similar in size to a #2 pencil), yields around 100mg of hair, which serves as the optimal quantity for both screening and subsequent confirmation. For EtG-related tests, additional or more extensive testing involving over 10 panels, a 150mg sample is advisable. It's suggested to measure this using a jeweler's scale. If scalp hair is unavailable, an equivalent weight of body hair can be used. The term 'head hair' specifically refers to scalp hair, whereas 'body hair' includes all other hair types (e.g., facial, axillary, etc.).
Process Overview
Laboratory processing of a drug test comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the introductory step of organizing a sample within a laboratory's framework. This step includes ensuring the sample's secure sealing and shipment, assigning a random Laboratory Accessioning Number (LAN), and filling in any missing information not covered by an electronic chain of custody system.
Screening acts as a preliminary evaluation for misuse of drugs. Even though Screening is economically efficient for excluding drug use in numerous samples, a positive result must be confirmed for legal proceedings. Presumptive positive samples require a follow-up confirmation.
For samples indicated as presumptively positive during Screening, additional hair is retrieved from the original sample to prepare for Extraction. In this procedure, drug extraction from hair occurs at significantly lower concentrations compared to other methods (like urine or oral fluid), attributing to the complexity of hair drug analysis.
Confirmation of any initial positive screening is conducted through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptive positive are washed prior to confirmation as necessary. The entire workflow from Accessioning through Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and in alignment with ISO / IEC 17025 standards.

Limitations:
Note: The term "hair follicle tests" is commonly used, though actual analysis is performed on the hair strand rather than 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.
