Hair Follicle Drug Testing - Crow Reservation, MT

What it is, How it works

Hair testing is now recognized as an effective means for detecting drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering a prolonged record of substance use. When extracted near the scalp, hair samples can detect alcohol and drugs for up to a quarter of a year. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches with around 200 hair strands (approximately the size of a #2 pencil) taken nearest to the scalp results in 100mg of hair, which is the optimal sample for evaluation. For EtG, additional tests, and analyses over 10 panels, 150mg of the sample is advised. It's recommended to measure the specimen using a jeweler’s scale. If scalp hair can't be obtained, an equivalent amount of body hair is acceptable. The term head hair specifically refers to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial processing of a sample into the laboratory’s system, which includes confirming proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry missing from an electronic chain of custody system.

Screening provides an initial assessment for drugs of abuse. While Screening offers a cost-effective method to exclude drug usage for most samples, a positive result requires confirmation to be court-admissible. Samples that show presumptive positive results in Screening need a secondary confirmation.

For samples showing presumptive positives in Screening, additional hair is extracted from the original sample for Extraction. Drugs are then extracted from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

To confirm any positive Screening result, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are employed. All samples that are presumptively positive are washed prior to confirmation, if necessary. From Accessioning to Confirmation, the entire laboratory process is evaluated in compliance with both the CAP (College of American Pathologists) Hair guideline and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which offer a shorter detection period.
• Cheating is challenging: Cheating on a hair drug test is extremely difficult, ensuring more reliable results.
• Offers historical insight: It can establish a drug use pattern over time, rather than detecting only recent use.

Limitations:

• Unable to reveal recent use: It takes roughly 5-7 days for drugs to be noticeable in hair.
• Expense: Hair drug tests generally cost more than other drug testing methods.
• Result variations: Hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests", these tests analyze the hair strand rather than the follicle below 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.
