Hair Follicle Drug Testing - Wilmore, PA

What it is, How it works

Hair testing is recognized as a potent method for identifying the use of alcohol and drugs. Hair captures a comprehensive history of drug and alcohol use by embedding biomarkers in its growing fibers. When collected near the scalp, hair can offer approximately a 3-month detection window for alcohol and various drugs. It is easy to collect, difficult to tamper with, and straightforward to ship.

A sample of 1.5 inches of around 200 strands of hair (roughly the size of a #2 pencil) nearest the scalp would yield 100mg of hair, which is the optimal sample size for analysis and verification. For EtG, additional tests, or evaluations beyond 10 panels, 150mg of the sample is preferred. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is not available, a comparable amount of body hair can be collected. References to head hair pertain solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four fundamental stages in the laboratory processing of a drug test include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into a laboratory system. This step involves ensuring the sample was securely sealed and appropriately shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any further data input not supplied by an electronic chain of custody system.

Screening consists of an initial rapid assessment for drugs of abuse. Although Screening is an economical approach to dismiss drug use in most samples, positive screens require confirmation to be valid in legal contexts. Any samples that appear positive in Screening demand secondary confirmation.

Should a sample appear positive in the Screening phase, additional hair is extracted from the original sample for Extraction. In this phase, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most intricate method to execute.

Verification of any positive screen result is performed through GC/MS, GC/MS/MS or LC/MS/MS. All samples presumed positive are cleansed before confirmation as necessary. The entire laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can recognize drug use for as long as 90 days, unlike urine tests which have a shorter span.
• Challenging to deceive: Cheating a hair drug test is notably difficult, ensuring more reliable results.
• Chronological data provision: It offers a timeline of drug use over time, rather than simply recent consumption.

Limitations:

• Inability to detect immediate use: It requires about 5-7 days for drugs to become apparent in hair.
• Expense: Hair drug tests tend to be more costly than alternative drug testing techniques.
• Result variability: Characteristics such as hair color and personal hair growth differences can impact the level of drug metabolites detected in the hair.

Note: While commonly known as "hair follicle tests", the analysis is conducted on the hair strand itself and not the follicle located 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.
