In Freeport, Pennsylvania, Accredited Drug Testing provides thorough hair follicle drug screening. Specializing in hair testing, we have centers across the nation ready to conduct these tests. Typically, 1.5 to 2 inches of head or body hair is required. Our testing options include screening for drugs, alcohol/ETG, and custom protocols.
Recent trends in drug testing favor the hair follicle method. Organizations like employers, courts, and substance abuse specialists increasingly choose this method over conventional urine tests. Ideal for zero-tolerance policies, hair tests offer up to 90 days of detection, monitored collection, and are hard to tamper with. However, for recent drug use within five days, urine testing remains precise.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing stands as an effective method for identifying drug and alcohol consumption. Hair retains a longer history of substance usage by capturing biomarkers within the hair strand's fibers. When hair is collected near the scalp, it offers a detection range that can extend up to 3 months for identifying alcohol and other drugs. Hair collection is straightforward, not easily tampered with, and convenient to transport.
A sample measuring 1.5 inches with roughly 200 hair strands (around the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the ideal amount for screening and confirmation. For EtG, additional tests, and/or panels beyond 10, a specimen size of 150mg is advisable. It is suggested to measure the specimen using a jeweler’s scale. In cases where scalp hair is not available, an equivalent portion of body hair can be used. "Head hair" refers specifically to scalp hair only, while "body hair" encompasses all other types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory’s system. This step includes confirming the proper seal and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entries not covered by an electronic chain of custody system.
Screening serves as a preliminary assessment for drug use. Though Screening effectively excludes drug usage across most samples, a positive screen necessitates confirmation to be admissible in court. Samples that preliminarily test positive in Screening require further confirmation.
Upon a presumptive positive result in the Screening phase, additional hair is extracted from the initial specimen for the Extraction process. Here, drugs are isolated from hair at significantly lower concentrations than with other methods (e.g., urine or oral fluid), highlighting why hair drug testing is notably challenging to conduct.
Confirmation of any positive screening is carried out through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo necessary washing prior to confirmation. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests", the test specifically analyzes the hair strand rather than the hair 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.
