Accredited Drug Testing offers comprehensive hair follicle drug assessments in Glenallen, Missouri. For those requiring a hair-based drug or alcohol screening, Accredited Drug Testing's expertise lies in hair testing, and facilities are available across all cities Nationwide for conducting these tests. Typically, 1.5 to 2 inches of hair from the crown or elsewhere is necessary. Hair analyses can detect drugs, alcohol/ETG, among other tailored options.
In recent years, hair follicle testing has increasingly become a preferred method for drug screening. Widespread among employers, judges, and addiction specialists, hair-based drug tests often replace traditional urine tests. Such tests are favored by employers enforcing strict anti-drug policies, courts, and probation personnel. The major advantage lies in its extensive detection window of drug usage, often up to 90 days, collected under supervision, and minimally susceptible to tampering. Yet, for identifying drug use within the past 5 days, urine tests maintain their precision and reliability.

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. It offers an extensive timeline of alcohol and drug intake by capturing biomarkers in the hair strand as it grows. When sourced near the scalp, hair can provide a detection period of up to 3 months for alcohol and drugs. The hair collection process is straightforward, hard to tamper with, and convenient for shipping.
A sample measuring 1.5 inches with around 200 hair strands (similar to a #2 pencil thickness) taken closest to the scalp provides 100mg of hair, which is the optimal amount for evaluation and verification. For EtG, additional tests, and/or panels exceeding 10, a sample of 150mg is advisable. We suggest using a jeweler's scale to weigh the sample. In the absence of scalp hair, an equivalent amount of body hair can be utilized. When referencing head hair, it pertains solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The core stages in the lab procedure of a drug testing result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is processed into the lab’s system. This includes checking that the sample was appropriately sealed and sent, allocating a unique LAN (Laboratory Accessioning Number), and finalizing any extra data input not managed by an electronic chain of custody system.
Screening provides an initial rapid test for drugs of abuse. While it serves as a cost-efficient means to eliminate drug use in a majority of samples, a positive screening requires verification to hold up in legal proceedings. Samples that show presumptive positivity in Screening must undergo a follow-up confirmation.
If a sample indicates presumptive positivity during Screening, more hair is extracted from the initial sample and readied for Extraction. At this phase, drugs are extracted from hair at a lower concentration compared to other methods (e.g., urine or oral fluid), which contributes to hair drug screening being the most challenging method to execute.
Any positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation as necessary. Each step of the lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Note: Though commonly called "hair follicle tests", the procedure assesses the hair strand and not the follicle under 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.
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.
