Accredited Drug Testing in Centerville, Pennsylvania offers comprehensive hair follicle drug testing services. Whether you need a test for drugs or alcohol, our specialty lies in hair testing. We have numerous centers across all cities Nationwide ready to conduct these tests. Generally, you'll need 1.5 to 2 inches of hair, either from your head or body, which can be analyzed for drugs, alcohol/ETG, or other personalized testing methods.
Recently, hair follicle drug testing has gained popularity over other methods. Many organizations, such as employers, courts, and substance abuse experts, prefer hair testing over the typical urine test. This method is particularly favored by employers with zero-tolerance policies, judicial systems, and probationary individuals. The primary advantage of hair testing is its extended drug detection period, up to 90 days, carried out in a monitored environment and nearly impossible to tamper with. However, for detecting recent substance use within the last 5 days, urine tests are still considered most precise.

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair retains evidence of alcohol and drug use within the fibers of the hair shaft, providing a lengthy history of substance intake. When collected near the scalp, hair offers approximately a 3-month detection period for alcohol and drugs. Collection is straightforward, manipulation is challenging, and transport is uncomplicated.
A 1.5-inch hair sample comprising approximately 200 strands (similar in size to a #2 pencil) positioned nearest the scalp yields 100mg, which is an optimal sample size for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, 150mg of the sample is advisable. It's advisable to weigh the sample using a jeweler’s scale. In cases where scalp hair is unavailable, a comparable amount of body hair is suitable. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other varieties (facial, axillary, etc.).
Process Overview
The core steps in lab drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the sample's initial processing within a lab’s setup, ensuring proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent from an electronic chain of custody system.
Screening performs a preliminary check for abuse substances. While cost-effective for ruling out drug use in most samples, a positive screen requires confirmation to be legally valid. Presumptively positive samples in Screening necessitate further confirmation.
For samples with presumptive positives in Screening, additional hair is extracted from the original sample and prepped for Extraction. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), thus making hair drug screening the most intricate method to execute.
Confirmation of any positive screen result employs GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed pre-confirmation as necessary. The complete lab process, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Limitations:
Note: Despite being termed "hair follicle tests", the focus is on analyzing 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.
