In Hillsdale, Missouri, Accredited Drug Testing offers comprehensive hair follicle testing services. Whether for drugs or alcohol, our specialization in hair testing is backed by nationwide facilities ready to conduct such tests. Generally, 1.5 to 2 inches of hair from the head's crown or even the body can be used. Our tests cover a range of substances, including drugs and alcohol/ETG, with options for specialized analysis.
The trend in drug testing is increasingly favoring hair follicle tests over traditional methods. A growing number of employers, legal systems, and substance abuse experts prefer the hair test. It's particularly favored in zero-tolerance workplaces, for court mandates, or probationary checks. The main advantage is its ability to detect drug use over a longer span, up to 90 days, when collected under observation, making it tamper-proof. Yet for identifying very recent drug use, a urine test remains the most precise.

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the growing hair strand, hair serves as an archive for long-term alcohol and drug use. When hair is collected near the scalp, it provides an approximate 3-month detection window for substances. Collection of hair is straightforward, challenging to tamper with, and convenient to transport.
A sample of about 200 hair strands (around the size of a #2 pencil), measuring 1.5 inches closest to the scalp, yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, or those beyond 10 panels, a specimen weight of 150mg is suggested. It's advisable to weigh the specimen using a jeweler’s scale. If scalp hair isn't accessible, a comparable quantity of body hair is collected. Reference to head hair pertains solely to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The core stages in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab’s system. It involves ensuring that the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.
Screening entails a preliminary rapid test for drugs of abuse. Though cost-effective for ruling out drug usage in most samples, a positive screening result necessitates confirmation for legal admissibility. Samples with a presumptive positive result from Screening require further verification.
Should a sample show presumptive positivity in Screening, additional hair is taken from the initial specimen for Extraction. This phase involves extracting drugs from hair at lower concentrations than other methods (e.g., urine or oral fluid), thus making hair drug screening the most challenging methodology.
Confirmation of any positive screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation, as needed. The entire process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation 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.
