Accredited Drug Testing offers comprehensive hair follicle drug tests in Hickory Hill, Pennsylvania. Specializing in both hair drug and alcohol testing, we have Nationwide centers that conduct hair tests. Typically, at least 1.5 to 2 inches of hair from the crown or body is required. Hair tests can detect drugs, alcohol/ETG, and other specified options.
Over recent years, hair follicle testing has become a preferred drug test method. Many employers, courts, and Substance Abuse specialists now opt for hair tests over urine tests. These tests are useful for organizations enforcing zero-tolerance policies, courts, and those on probation. Notably, hair tests detect drug use over a 90-day period, are conducted under observation, and are hard to tamper with. However, for recent drug usage within 5 days, urine tests remain more precise.

Hair testing is widely recognized as an effective method for detecting drug and alcohol use. Hair offers a comprehensive timeline of alcohol and drugs by embedding biomarkers within the fibers of the growing strand. When taken near the scalp, hair can reveal drug and alcohol use over an approximate 3-month period. Hair collection is straightforward, fairly resistant to tampering, and simple to transport.
A sample consisting of a 1.5-inch length of roughly 200 hair strands (comparable to the size of a #2 pencil) nearest the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, add-ons, or tests involving more than 10 panels, a 150mg specimen is advisable. We suggest using a jeweler’s scale for weighing the sample. If scalp hair isn't available, an equivalent amount of body hair should be used. By "head hair," we mean scalp hair alone. "Body hair" refers to every other type (facial, axillary, etc.).
Process Overview
The laboratory processing for a drug test result comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial sample integration into a laboratory’s system. This process checks whether the sample was appropriately sealed and transported, allocates a random LAN (Laboratory Accessioning Number), and completes any extra data entry omitted by an electronic chain of custody system.
Screening conducts an initial rapid assessment for drugs of abuse. Screening provides a cost-effective method to dismiss drug use in most samples; however, for legal admissibility, a positive result requires confirmation. Any samples with a presumptive positive in Screening necessitate a subsequent confirmation.
Should a sample be presumptive positive at the Screening stage, additional hair is extracted from the original specimen and prepared for Extraction. In Extraction, drugs are retrieved from hair at much lower concentrations than in other methods (like urine or oral fluid), underscoring the complexity of hair drug screening.
Confirmation of positive screening results is performed using GC/MS, GC/MS/MS or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing if needed. The overall lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Limitations:
Note: While often called "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.
