In Grand River, Iowa, Accredited Drug Testing provides comprehensive hair follicle drug testing services. For those needing drug or alcohol hair testing, our centers nationwide are equipped for such procedures. Typically, 1.5 to 2 inches of hair from the head or body is required for analysis. These tests can identify drugs, alcohol/ETG, or other specific testing needs.
Recently, hair follicle drug testing has become a prevalent method for substance analysis. It is preferred by employers, judicial systems, and Substance Abuse experts over the traditional urine test. Employers implementing zero-tolerance policies, courts, and those on probation favor this method. Its main advantage is the extended detection window of up to 90 days, with a supervised collection process reducing tampering. Urine tests, however, are the most accurate for detecting usage within the last 5 days.

Hair testing is now perceived as a robust method for identifying drug and alcohol consumption. Hair offers a comprehensive record of alcohol and other drugs by capturing biomarkers within the fibers of the developing hair strand. When extracted near the scalp, hair delivers up to around a three-month detection span for alcohol and various drugs. Hair is easy to collect, relatively hard to manipulate, and straightforward to send.
A 1.5-inch segment consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp will yield 100mg, which is the optimal sample for both screening and verification. For EtG, additional analyses, and/or examinations beyond 10 panels, a 150mg sample is suggested. It is advised to measure the sample on a jeweler’s scale. If scalp hair isn't present, the same quantity of body hair is acceptable. When speaking of head hair, we solely mean scalp hair. Body hair refers to all other types (e.g., facial, axillary, etc.).
Process Overview
The key elements in a laboratory's drug test result assessment include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary stage of introducing a sample into a lab's system. This step involves checking if the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and adding any additional data that isn’t available from an electronic chain of custody framework.
Screening offers a quick initial assessment for drug abuse. Although Screening is a budget-friendly method to exclude drug usage in most samples, a positive screen must be verified for court admission. Any samples testing presumptively positive during Screening need a follow-up validation.
Should a sample test presumptively positive in Screening, additional hair from the initial sample is extracted and processed for Extraction. Here, drugs are extracted from hair at concentrations much lower than other techniques (for example, urine or oral fluid), which makes hair drug screening challenging.
Positive screening results confirmation is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples returning presumptive positives undergo washing before confirmation. The entire lab procedure from Accessioning to Confirmation is scrutinized in accordance with both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation 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.
