In Progress, Pennsylvania, Accredited Drug Testing offers comprehensive services for hair follicle drug testing. Our expertise in hair and alcohol tests extends nationwide, with local centers equipped to execute these exams. For a hair test, you'll typically need 1.5 to 2 inches from your head or body. Specialized hair tests can detect drugs, alcohol, ETG, among other substances.
Hair follicle testing has become increasingly popular in recent times. It's now favored by employers, courts, and substance abuse professionals for its extended detection times compared to the traditional urine tests. Hair tests, often preferred due to their accuracy over a 90-day period, almost eliminate the chance for tampering. Yet, for recent usage within a few days, urine tests remain most precise.

Hair analysis has emerged as an effective instrument for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of alcohol and drug usage by capturing markers within the fibers of the developing hair thread. When cut near the scalp, hair can indicate up to a three-month period for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and simple to send.
A sample measuring 1.5 inches, consisting of roughly 200 hairs (about the size of a #2 pencil) adjacent to the scalp, yields 100mg of hair, which is an optimal amount for examination and verification. For EtG, additional tests, and panels exceeding 10, a 150mg specimen is advised. We suggest using a jeweler’s scale to measure the specimen weight. If scalp hair is not available, a comparable quantity of body hair is an alternative. References to head hair pertain to scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves incorporating the sample into a laboratory’s system. This encompasses checking that the sample is sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and performing any extra data input not covered by an electronic chain of custody.
Screening is a preliminary rapid assessment for abused substances. While Screening is cost-effective for excluding drug use in the majority of specimens, a positive screen must be verified for legal acceptability. Any samples indicating potential positive results during Screening must undergo further confirmation.
Should a sample appear positive during the Screening phase, additional hair is taken from the original sample for Extraction. This stage involves extracting drugs from hair at a lower concentration than other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to conduct.
Confirmation of any screening positivity is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleansed before confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation is evaluated under CAP (College of American Pathologists) standards for Hair and ISO / IEC 17025 certification.
Advantages of hair drug testing:
Limitations:
Note: The term "hair follicle tests" is misleading as the test analyzes 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.
