Accredited Drug Testing provides comprehensive hair follicle drug assessments in Calverton Park, Missouri. If a hair drug or alcohol analysis is required, Accredited Drug Testing excels in hair testing, with facilities in all cities nationwide equipped to conduct hair tests. Hair from the crown or body (1.5 to 2 inches) is typically required. Hair evaluations can detect drugs, alcohol/ETG, and other tailored options.
In recent times, hair follicle drug testing has become more prevalent in drug screening protocols. Numerous employers, legal entities, and substance abuse experts now specify hair drug tests over conventional urine tests. Employers, courts, and probation cases adopt hair tests for strict zero-tolerance policies. The significant advantage is a detection window of up to 90 days, performed under observation and is near-impossible to falsify. Urine tests, however, remain precise for recent drug use within 5 days.

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a historical record of alcohol and drugs by embedding biomarkers within the strands of hair as it grows. When taken from near the scalp, hair can reveal a detection period of up to roughly three months for alcohol and drugs. It is straightforward to collect, relatively hard to tamper with, and convenient to mail.
A 1.5-inch segment consisting of approximately 200 hairs (comparable to the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, which is the ideal amount for both screening and confirmation. For EtG, additional tests, and/or tests surpassing 10 panels, a 150mg sample is advised. It's beneficial to measure the sample on a jeweler’s scale. Should scalp hair not be present, a comparable quantity of body hair can be used. Here, head hair denotes only scalp hair, while body hair encompasses other hair types (facial, underarm, etc.).
Process Overview
The key steps in the lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the first processing phase when a sample is integrated into the lab’s system. This step includes confirming proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and entering supplementary data not available via an electronic chain of custody system.
Screening involves a preliminary swift assessment for drugs of abuse. Though Screening offers a cost-effective solution to exclude drug use in most samples, any positive finding must be confirmed for court acceptance. Samples testing presumptively positive during Screening necessitate subsequent confirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample for Extraction. Here, drugs are removed from the hair at a concentration level much lower than other techniques (e.g., urine or oral fluid), highlighting why hair drug testing is most challenging.
Confirmation of any positive screening outcome is done through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that presumptively tested positive undergo washing prior to confirmation as required. The entire lab procedure from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair criteria and 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.
