Accredited Drug Testing provides comprehensive hair follicle drug screening services in Fairfield, Illinois. Whether you're in need of a hair drug or alcohol test, Accredited Drug Testing offers specialty hair testing, with Nationwide testing centers ready to conduct these assessments in any city. Generally, 1.5 to 2 inches of hair from the head's crown or body can be used. Hair tests may screen for drugs, alcohol/ETG, or other tailored testing options.
Recent trends in drug testing have favored hair follicle methods. Many employers, judicial systems, and Substance Abuse professionals now prefer hair drug tests to traditional urine samples. These tests support zero-tolerance policies in workplaces, courts, and probationary contexts. Hair follicle drug tests offer a key advantage: a longer detection window, usually up to 90 days, ensuring the samples remain secure and virtually tamper-proof. Nevertheless, for detecting very recent drug use within 5 days, urine tests remain the preferred standard.

Hair analysis is now recognized as a significant means for identifying substance intake. Hair offers a retrospective timeline by embedding chemical markers within its structure as it grows. Collected near the scalp, it can reveal approximately a three-month trace of alcohol and drugs. Hair collection is straightforward, hard to tamper with, and simple to transport.
A typical 1.5-inch hair sample, comprising about 200 strands akin to a #2 pencil, yields 100mg of hair, which is considered optimal for evaluations and confirmation. For EtG testing, add-ons, and/or screens exceeding 10 panels, a 150mg sample is preferred. It's advised to measure the specimen using a jeweler’s scale. In cases where head hair is lacking, a like quantity of body hair may be used. Head hair denotes only scalp hair, whereas body hair includes other types (facial, underarm, etc.).
Process Overview
The essential phases in lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the sample's initial entry into the lab’s system. This step ensures the sample was properly sealed and transported, allocates a random LAN (Laboratory Accessioning Number), and completes any pending data entry not covered by an e-chain of custody.
Screening offers a preliminary scan for substance abuse. Though Screening is an economical means to dismiss drug usage in the majority of samples, a positive outcome necessitates further verification for courtroom validity. All presumptive positives from Screening must undergo further confirmation.
A presumptive positive from the Screening phase leads to more hair being extracted from the original sample for Extraction. Here, drugs are retrieved from hair in lower amounts compared to other methods (e.g., urine or oral fluids), making hair drug screening one of the trickiest methods to execute.
Confirmation of a positive screen uses GC/MS, GC/MS/MS, or LC/MS/MS techniques. Every presumptive positive sample is cleansed before confirmation if required. The comprehensive lab process from Accessioning to Confirmation is overseen under CAP (College of American Pathologists) Hair qualification and accredited by ISO / IEC 17025 standards.

Note: Although often termed "hair follicle tests", the examination evaluates the hair strand and 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.

I needed a quick drug test for visitation with my children. I called at 6am they answered and set me up with a place a couple miles from my house to go get the test done, that was on Wednesday, I had the results on Friday afternoon and was able to see my kids on Saturday. Thank you for the help!
