Accredited Drug Testing offers comprehensive hair follicle drug assessments in Chesterton, Indiana. For those requiring hair or alcohol evaluations, we specialize in this area and have facilities Nationwide capable of conducting hair tests. Typically, 1.5 to 2 inches of hair from the head crown or body is necessary. Hair evaluations can screen for substances, alcohol/ETG, or be tailored for special requirements.
Recently, the preference for drug assessments has evolved to favor hair follicle testing. Many employers, judicial systems, and addiction specialists prefer it over traditional urine testing. Companies with strict drug-free mandates, legal entities, and those on probation utilize hair follicle screenings. These tests offer an extended detection window up to 90 days, involve supervised collection, and are challenging to tamper with. However, for recent substance use within 5 days, urine tests remain more precise.

Hair testing is regarded as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and illicit substances by retaining biomarkers within the fibers of each maturing hair shaft. When obtained from the scalp area, hair offers nearly a 3-month detection timeline for substances like alcohol and drugs. The collection process is straightforward, somewhat resistant to tampering, and convenient for transport.
A 1.5-inch segment consisting of roughly 200 hair strands (about equivalent to a #2 pencil's thickness) near the scalp yields 100mg of hair, which is the preferred sample size for both screening and verification. For EtG, additional testing, and/or those above 10 panels, a 150mg sample is suggested. Using a jeweler's scale to weigh the sample is advisable. Should scalp hair be unavailable, a similar quantity of body hair can be used. The term head hair exclusively refers to scalp hair, while body hair encompasses all other hair types (face, axillary, etc.).
Process Overview
The laboratory analysis of drug test samples includes the following four stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is first entered into the lab's system. This process confirms the proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not covered by an electronic chain of custody system.
Screening provides an initial cursory investigation for drugs of abuse. Although it's a cost-effective method for excluding drug use in most cases, positive screenings require confirmation for legal acceptance. Thus, any samples indicated as positive in this phase need subsequent verification.
In instances where a sample returns a presumptive positive result during Screening, additional hair is taken from the original sample for the Extraction phase. Here, drugs are extracted from the hair at significantly lower concentrations compared to other methods (e.g., urine or saliva tests), adding to the complexity of hair drug testing.
Confirmation for a positive screening outcome employs techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive specimens undergo washing before confirmation if needed. The full laboratory process, from Accessioning to Confirmation, is scrutinized under CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although frequently called "hair follicle tests", the examination targets the hair strand, not the follicle under the skin.

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.
