Hair Follicle Drug Testing - Alleghany, VA

What it is, How it works

Hair testing is recognized as a potent means for detecting drug and alcohol consumption. Hair captures a long-term record of substances by holding biomarkers within the fibers of the growing strand. When gathered near the scalp, hair offers up to a 3-month window for detecting substances like alcohol. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.

A 1.5-inch segment of about 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal amount for screening and verification. For EtG, supplementary tests, and/or panel tests exceeding 10, 150mg of the sample is advised. It’s recommended to weigh the hair sample using a jeweler’s scale. If no scalp hair is present, an equivalent quantity of body hair can be used. References to head hair pertain to scalp hair only, whereas body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four key steps in laboratory processing of drug test results are Accessioning, Screening, Extraction, and Confirmation.

Accessioning relates to the primary processing of a sample in a laboratory’s framework. This includes confirming the proper sealing and receipt of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any further data input not covered by an electronic chain of custody system.

Screening pertains to an initial rapid evaluation for substances of abuse. While Screening is a cost-efficient method to exclude drug use in most samples, a positive result requires confirmation for court acceptability. Samples presumed positive during Screening necessitate secondary confirmation.

Should a sample test positive under Screening, additional hair is taken from the original sample for Extraction. In Extraction, substances are isolated from hair at notably lower concentrations than other methods (e.g., urine or oral fluid), highlighting why hair drug analysis is among the most challenging methods.

Confirmation of any positive results from screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positives are cleansed prior to confirmation as needed. The entire lab procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug usage up to 90 days, whereas urine tests have a shorter detection span.
• Hard to alter: It is exceedingly tough to compromise a hair drug test, enhancing result precision.
• Offers historical insights: It provides a drug use trend over time, not just short-term usage.

Limitations:

• Inability to detect recent usage: Drugs become noticeable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests generally cost more than alternative methods.
• Result variability: Aspects like hair color and individual growth rate can impact drug metabolite levels in hair.

Note: Despite being called "hair follicle tests", the analysis examines the hair strand, not the follicle beneath 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.
