Accredited Drug Testing provides thorough hair follicle drug testing services in Arrow Point, Missouri. For individuals needing a hair drug or alcohol test, Accredited specializes in hair analysis, with centers nationwide capable of conducting these tests. Typically, 1.5 to 2 inches of hair from the head's crown or body suffice. These tests analyze substances like drugs and alcohol/ETG, among other options.
The use of hair follicle drug tests has increased recently as a method for drug testing. Employers, courts, and substance abuse specialists often require hair tests rather than urine tests. These tests are favored by employers with no-drug policies, the judicial system, and probation services. Their advantage is a longer detection window, up to 90 days, performed under supervision, which is difficult to meddle with. However, for detecting recent use within five days, urine tests remain the most accurate.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. It offers a prolonged record of substances due to the embedding of biomarkers within the strands during hair growth. When sampled near the scalp, hair can indicate drug and alcohol use up to roughly three months prior. Collecting hair is straightforward, it's challenging to tamper with, and it's convenient to send for analysis.
A sample measuring 1.5 inches comprising about 200 hair strands (comparable to the diameter of a #2 pencil) taken nearest to the scalp results in a 100mg hair yield, which is ideal for both preliminary and confirmatory testing. For EtG, additional tests, or tests beyond 10 panels, a 150mg sample is advisable. Using a jeweler’s scale for specimen weight estimation is suggested. Should scalp hair be unavailable, a similar quantity of body hair can be collected. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (such as facial or axillary hair).
Process Overview
The key stages in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially entered into the laboratory's workflow. This step involves ensuring the sample was properly sealed and transported, assigning it a random LAN (Laboratory Accessioning Number), and performing any supplementary data entry not handled by an electronic chain of custody system.
Screening is a preliminary check for substances of abuse. Although it is an economical approach to exclude drug use in the majority of cases, a positive result from Screening requires confirmation to be legally defensible. Samples that test positive in Screening necessitate a confirmatory test.
If Screening indicates possible drug presence, more hair is extracted from the original sample for further preparation in the Extraction stage. In this phase, drugs are extracted at a much lower concentration than other methods (like urine or oral fluid), which makes hair drug screening particularly challenging.
Positive Screening results go through Confirmation using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleansed before confirmation as required. The entire process from Accessioning to Confirmation is verified under both the CAP (College of American Pathologists) Hair guidelines 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.
