Accredited Drug Testing provides comprehensive hair follicle testing services in Weston, Pennsylvania. If you require testing for drugs or alcohol via hair samples, Accredited Drug Testing is the expert. We have facilities in cities across the country ready to conduct these tests. Typically, 1.5 to 2 inches of hair from the crown or body hair, where applicable, is required. These tests can determine the presence of drugs, alcohol/ETG, and can accommodate various tailor-made testing requirements.
Hair follicle drug testing has increasingly become part of the standard testing process in recent years. Employers, legal entities, and substance abuse professionals prefer hair drug tests over the conventional urine tests. Hair follicle testing suits organizations with strict no-drug policies, judicial systems, and individuals on probation. The prominent advantage of using a hair test is its extended detection period, usually up to 90 days, with observed sampling to prevent tampering. However, for detecting recent drug use (within the last 5 days), urine testing remains more accurate.

Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive history of substance use by locking biomarkers in the strands of growing hair. When collected near the scalp, hair can offer a detection span of up to 3 months for alcohol and other substances. Collecting hair is straightforward, somewhat resistant to tampering, and simple to transport.
A 1.5-inch sample comprising approximately 200 hair strands (around the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the ideal quantity for screening and confirmation. For EtG, additional panels, and/or tests exceeding 10 panels, a sample of 150mg is advised. Using a jeweler’s scale for weighing the sample is recommended. If scalp hair is unavailable, a similar quantity of body hair can be collected. When mentioning head hair, we refer solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
Laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory's workflow. This step includes verifying that the sample was sealed and sent correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.
Screening involves a preliminary check for drugs of abuse. While Screening is a cost-efficient method to eliminate drug usage in most samples, a positive screen must be confirmed to be valid in legal proceedings. Samples that are presumptively positive during Screening need a secondary confirmation.
If Screening results are presumptively positive, additional hair is taken from the initial sample and readied for Extraction. During this phase, drugs are extracted from hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging technique to perform.
Confirmation of any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as necessary. The entire lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

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.
