Accredited Drug Testing offers comprehensive hair follicle drug assessments in Willow Street, Pennsylvania. If a hair drug or alcohol analysis is required, Accredited Drug Testing excels in such diagnostics, with facilities in cities across the Nation capable of conducting hair analyses. Typically, 1.5 to 2 inches of hair from the head or body can be used. Hair assessments may detect drugs, alcohol/ETG or include other bespoke hair analysis options.
In the past few years, hair follicle drug testing has increasingly been employed in drug testing methods. Many employers, judicial systems, and Substance Abuse experts request a hair drug test over a conventional urine test. Companies with zero-tolerance drug policies, the courts, and individuals on probation often rely on hair follicle tests. The main advantage of this test is its extended drug detection period, up to 90 days, obtained through an observed process, making it nearly impossible to falsify. Yet, for appraising drug use within the last 5 days, a urine test remains the most 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 is regarded as a significant method for detecting drug and alcohol consumption. Hair ensures a long-term record of alcohol and other drugs by embedding biomarkers within the strands of the hair as it grows. When sourced near the scalp, hair can offer a detection timeframe of nearly 3 months for alcohol and other drugs. Hair is easy to collect, somewhat challenging to tamper with, and simple to transport.
A sample size of 1.5 inches consisting of approximately 200 hair strands (akin to the diameter of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal sample for testing and validation. For EtG enhancements and/or tests exceeding 10 panels, 150mg of the specimen is advised. It is suggested to measure the specimen using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be gathered. When referring to head hair, we specifically mean scalp hair. Body hair denotes any other hair types (facial, axillary, etc.).
Process Outline
The key four steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into a lab's system. This process encompasses the verification that the sample was securely sealed and dispatched correctly, assigning a unique LAN (Laboratory Accessioning Number), and finishing any supplementary data entry not furnished by an electronic chain of custody system.
Screening consists of a preliminary swift assessment for drugs of abuse. Although Screening is an economical approach to exclude drug usage in most samples, a positive screening requires confirmation to be acceptable in legal settings. Samples identified as presumptively positive in Screening necessitate a further confirmation.
If a sample is marked presumptively positive in the Screening stage, additional hair is extracted from the primary specimen and readied for Extraction. In this phase, drugs are extracted from hair at considerably lower concentrations than in other procedures (e.g., urine or oral fluid), contributing to hair drug screening being regarded as the most intricate methodology.
Verification of any positive screening outcome is conducted through GC/MS, GC/MS/MS or LC/MS/MS. All samples deemed presumptively positive are cleansed prior to confirmation as deemed necessary. The full laboratory process, from Accessioning to Confirmation, is conducted under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Benefits of hair drug testing:
Disadvantages:
Note: Though frequently termed as "hair follicle tests", the test evaluates the hair strand, not the hair follicle positioned under 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.
