Accredited Drug Testing provides comprehensive hair follicle drug testing in Concord, Missouri. For those needing hair drug or alcohol tests, our expertise lies in hair testing, available at centers nationwide. At least 1.5 to 2 inches of hair from the crown of the head or body suffices in most instances. Tests can detect drugs, alcohol/ETG, or offer custom hair testing solutions.
In recent times, drug testing methods have increasingly adopted hair follicle drug tests. More employers, courts, and substance abuse experts demand this over traditional urine tests. Hair tests are favored by zero-tolerance policy employers, courts, and probationers due to their longer drug use detection window, typically up to 90 days. Conducted under observation, it's difficult to tamper with, yet for recent 5-day drug use, urine tests remain most accurate.

Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair captures a comprehensive history of substances by embedding biomarkers within the fibers of the hair shaft as it grows. A sample collected near the scalp can yield approximately a 3-month detection timeline for various substances. Hair is easy to procure, challenging to tamper with, and convenient to mail.
A sample measuring 1.5 inches of around 200 hair strands (comparable to a #2 pencil in thickness) situated nearest the scalp provides 100mg of hair, which is ideal for examination and validation. For EtG, additional tests, or panels exceeding 10, a total of 150mg of hair is suggested. It is advised to measure the sample using a jeweler’s scale. Should head hair be unavailable, an equal volume of body hair can be used. Head hair refers exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome encompasses the following four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial phase where a sample is logged into a laboratory’s framework. This step includes ensuring the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional data input absent from an electronic chain of custody system.
Screening entails a rapid preliminary assessment for substance abuse. Although Screening is a cost-efficient approach to eliminating drug use from most samples, a positive result must be verified to stand up in legal settings. All samples that test presumptive positive during Screening necessitate further validation.
Should a sample yield a presumptive positive during Screening, supplementary hair is extracted from the main sample for the Extraction process. In Extraction, drugs are derived from hair at substantially lower concentrations than other procedures (e.g., urine or oral fluid), rendering hair drug testing the most intricate process to undertake.
Confirmation of a positive screen is executed through GC/MS, GC/MS/MS, or LC/MS/MS methods. Before confirmation, all samples that test presumptive positive are cleansed as deemed necessary. The complete laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair criteria and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed as "hair follicle tests", the evaluation itself examines the hair strand rather than the follicle beneath the scalp

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.

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.
