Accredited Drug Testing provides comprehensive hair follicle drug testing services in Readfield, Maine. For those in need of hair drug or alcohol testing, our specialization in hair testing and a vast network of centers across the nation make it convenient to schedule a hair test. Typically, you need 1.5 to 2 inches of hair from your head or other body parts. Hair samples can be tested for drugs, alcohol/ETG, or tailored testing options.
Over the past years, drug testing methods have increasingly incorporated hair follicle drug testing. This shift is driven by employers, legal institutions, and substance abuse experts who now prefer hair tests over traditional urine tests. Hair follicle tests are favored by zero-tolerance employers, judicial systems, and probationary services due to their extensive detection window of up to 90 days and monitored collection, making cheating nearly impossible. However, for detecting recent drug use, urine tests remain the most precise option.

Hair testing has become recognized as an effective means for detecting drug and alcohol consumption. Hair captures a historical record of substance use by encapsulating biomarkers within the growing hair strand fibers. When extracted near the scalp, hair offers a detection window for alcohol and other drugs extending up to roughly three months. Hair is easy to collect, challenging to tamper with, and convenient to transport.
A 1.5-inch segment consisting of approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp produces 100mg of hair, which is the optimal quantity for screening and confirmation. For EtG, additional testing, or analyses above 10 panels, a sample size of 150mg is suggested. We recommend using a jeweler’s scale for weighing the specimen. If scalp hair is not available, an equivalent quantity of body hair may be used. References to head hair specifically pertain to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The four essential stages in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial handling of a sample in a laboratory’s system, which involves confirming proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not provided by an electronic chain of custody system.
Screening is a preliminary assessment for substances of abuse. While Screening is an economical method for ruling out drug use in most samples, a positive screen must be validated to be legally valid. Samples that show a presumptive positive in Screening require a subsequent confirmation.
If Screening indicates a presumptive positive, more hair is extracted from the initial sample for Extraction. During this phase, hair undergoes drug extraction at a notably lower concentration than in other testing methods (e.g., urine or oral fluid), thereby making hair drug screening the most challenging methodology to execute.
Validation of any positive screening outcome is carried out using GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives are cleansed prior to confirmation as necessary. The complete lab process, from Accessioning to Confirmation, undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and accreditation aligns with ISO / IEC 17025 criteria.

Limitations:
Note: Despite often being labeled as "hair follicle tests," the analysis is conducted on the hair strand, excluding 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.
