Hair Follicle Drug Testing - Prospect, MD

What it is, How it works

Hair testing is recognized as an effective method for identifying the use of drugs and alcohol. Hair captures a long-term record of substances by trapping biomarkers within the strands as they grow. When taken from near the scalp, hair offers a detection window of up to roughly three months for alcohol and various drugs. Hair collection is straightforward, hard to tamper with, and simple to transport.

A 1.5-inch portion from around 200 strands closest to the scalp will yield approximately 100mg of hair, ideal for screening and confirmation. For tests such as EtG, add-ons, or more than 10 panels, a 150mg sample is preferred. We advise measuring the specimen with a jeweler's scale. If scalp hair cannot be obtained, an equivalent amount of body hair is suitable. By head hair, we mean only the scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

Laboratory processing of a drug test comprises Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample within a lab’s framework. This includes ensuring the sample’s seal and shipment were intact, issuing a random LAN (Laboratory Accessioning Number), and fulfilling any remaining data entry not managed by an electronic chain of custody system.

Screening entails a quick preliminary check for drugs of abuse. While cost-effective in ruling out drug usage for most samples, a positive screen must be verified for court admissibility. Any samples testing positive in Screening must undergo secondary confirmation.

If Screening tests result in a presumptive positive, additional hair is extracted from the initial sample for Extraction. In Extraction, drugs are removed from the hair at lower concentrations than with other methods (e.g., urine or oral fluid), making hair drug testing the most challenging to conduct.

Confirmation of positive Screening results occurs using GC/MS, GC/MS/MS, or LC/MS/MS. All positive samples are thoroughly washed before confirmation if necessary. The laboratory process from Accessioning to Confirmation is reviewed against both the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can trace drug use for up to 90 days, unlike the urine tests with shorter detection periods.
• Hard to manipulate: Cheating a hair drug test is nearly impossible, enhancing result accuracy.
• Offers historical insights: Provides a timeline of drug use over time, rather than only recent usage.

Limitations:

• Limits in detecting recent usage: Drugs take about 5-7 days before becoming detectable in hair.
• Higher costs: Hair drug tests usually cost more than other drug testing methods.
• Result variability: Factors like hair color and individual growth differences can alter drug metabolite concentration in hair.

Note: Although often called "hair follicle tests", the examination is on the hair strand, not the follicle itself under the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

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.
