Accredited Drug Testing provides comprehensive hair follicle drug analysis in Markham, Illinois. For those needing a hair drug or alcohol screening, our expertise lies in hair testing with centers available across all cities nationwide. Generally, 1.5 to 2 inches of hair from the crown or body can be used. Hair tests are employed for drugs, alcohol/ETG, or other personalized options.
Recently, the use of hair follicle drug testing has increased. Employers, courts, and substance abuse professionals often opt for hair tests over standard urine tests. Hair tests are favored by employers with strict drug policies, legal systems, and those on probation. The main advantage of hair testing is a longer drug detection window, lasting up to 90 days, and its collection is observed and difficult to manipulate. However, for drug use in the past 5 days, urine tests remain most accurate.

Hair analysis is recognized as an effective method for detecting the consumption of drugs and alcohol. The fibers of growing hair strands retain biomarkers, offering an extended historical view of substance use. When hair is harvested near the scalp, it provides a detection timeframe of up to roughly three months for substances. Hair collection is straightforward, hard to tamper with, and simple to ship.
A 1.5-inch length comprising roughly 200 hair strands (approximately the size of a #2 pencil) closest to the scalp accumulates 100mg of hair, which is the perfect amount for both screening and confirmation. For EtG, additional testing, and/or panels exceeding 10, a 150mg sample is advisable. It's recommended to gauge the sample's weight with a jeweler’s scale. In the absence of scalp hair, a matching amount of body hair can be used. Reference to head hair pertains strictly to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
Processing a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary entry of a sample into a laboratory’s system. This stage ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any essential data input not documented by an electronic chain of custody.
Screening executes an initial, expeditious assessment for controlled substance use. While screening provides a cost-efficient means of negating drug use in a large portion of samples, a positive result needs confirmation for legal validity. Any screening-indicated positive samples necessitate secondary verification.
Should a sample test positive during Screening, additional hair is extracted from the original sample for further Extraction. At this juncture, drugs are drawn from hair at notably lower concentrations compared to other methods (e.g., urine or saliva), thus rendering hair drug screening a particularly challenging technique to perfect.
Confirmation of any positive screening is undertaken via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo washing before confirmation if required. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and attests to ISO / IEC 17025 standards.

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!
