Offering a comprehensive hair follicle drug testing service in Lynn, Indiana, Accredited Drug Testing is the go-to for hair drug or alcohol tests. Our expertise in hair analysis is matched by our testing centers operating in cities all over the country. Typically, 1.5 to 2 inches of hair from the head or body suffices for testing. Our hair tests are flexible, capable of detecting drugs, alcohol/ETG, or being customized according to varying needs.
Hair follicle drug testing has grown increasingly common recently, supplanting more traditional urine tests as the preferred choice among employers, courts, and Substance Abuse experts. Organizations with zero-tolerance drug policies, as well as courts and probation supervisors, are turning to this method. Its key advantage is the extended detection window, offering up to 90 days of drug use history. The sample collection process is observed, minimizing chances of deception. However, for drug use within the past 5 days, urine tests maintain superior accuracy.

Hair testing is recognized as a potent means for identifying drug and alcohol consumption. The hair captures a historical record of substances by embedding biomarkers within the hair strand as it grows. When obtained close to the scalp, hair offers a detection window of up to roughly three months for alcohol and other drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A specimen with a length of 1.5 inches consisting of approximately 200 hair strands (equivalent to a #2 pencil's thickness) closest to the scalp delivers 100mg of hair, the ideal quantity for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. We suggest assessing the specimen's weight with a jeweler’s scale. If scalp hair is absent, a similar amount of body hair may be obtained. Whenever head hair is mentioned, it refers specifically to scalp hair. Body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The four key phases in the lab analysis of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed within a lab’s system. This step ensures the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any needed data entry not covered by an electronic chain of custody system.
Screening involves a rapid preliminary assessment for drugs of abuse. While it's a budget-friendly approach to eliminate drug usage in the majority of samples, a positive screen must be verified for legal admissibility. Any samples showing presumptive positives during Screening need a secondary verification.
Should the sample be presumptively positive during the Screening phase, additional hair is taken from the original specimen and made ready for Extraction. Here, drugs are extracted from hair at a significantly lower concentration than in other methods (such as urine or oral fluid), making hair drug testing one of the most challenging methods to execute.
GC/MS, GC/MS/MS or LC/MS/MS is used to confirm any positive screening results. All presumptive positive samples undergo washing before confirmation when necessary. The entire laboratory process, from Accessioning through Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.

Note: Despite often being called "hair follicle tests", this test evaluates the hair strand itself and not the follicle under 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!
