Accredited Drug Testing provides comprehensive hair follicle drug tests in Rockville, Missouri. Whether you require a hair drug or alcohol test, Accredited Drug Testing excels in hair testing, with centers located nationwide, ready to carry out hair tests. Typically, you need 1.5 to 2 inches of head or body hair. Hair tests evaluate drugs, alcohol/ETG, or other tailored testing options.
Recently, drug testing methods increasingly incorporate hair follicle drug tests. Employers, legal systems, and substance abuse specialists often prefer hair tests over standard urine tests. Employers enforcing zero-tolerance drug policies use these tests, as do courts and individuals on supervision. A significant advantage of hair tests is the extended drug detection window, up to 90 days, making it hard to deceive. For detecting recent drug use within 5 days, urine tests remain the most precise.

Hair testing has become recognized as a robust method for identifying drug and alcohol usage. Hair captures a comprehensive history of alcohol and other substances by embedding biomarkers in the developing hair fibers. Collected near the scalp, hair can reveal up to a 3-month detection period for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch segment, roughly 200 strands of hair (comparable to the thickness of a #2 pencil) closest to the scalp provides 100mg, which is the optimal amount for screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg specimen is advised. It's suggested to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be acquired. Scalp hair refers exclusively to the hair on the head. All other hair types (facial, axillary, etc.) are categorized as body hair.
Process Overview
The primary steps in processing a drug test in a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a specimen into the laboratory’s system. This involves ensuring the sample was correctly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and completing any additional information entry not included by an electronic chain of custody.
Screening consists of a preliminary quick test for substance abuse. While Screening is an economical method to exclude drug use on most samples, a positive result must be verified to be court-admissible. Any samples with a presumptive positive result in Screening require further confirmation.
Should a specimen show a presumptive positive in the Screening phase, additional hair is drawn from the primary sample and readied for Extraction. During this step, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to perform.
Confirmation of any positive screening is executed via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the 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.
