Hair Follicle Drug Testing - Wescosville, PA

What it is, How it works

Hair testing is now recognized as a robust method for identifying drug and alcohol consumption. Hair serves as an extended timeline of alcohol and drug intake by capturing biomarkers within the strands' fibers as they grow. When obtained near the scalp, hair offers a detection range of up to around three months for both alcohol and drugs. It is easy to collect, comparatively tamper-resistant, and straightforward to transport.

A 1.5-inch segment of about 200 hair strands (akin to the width of a #2 pencil) nearest to the scalp yields about 100mg of hair, which is the optimal quantity for diagnostic and confirmatory purposes. For EtG, additional tests, or tests exceeding 10 panels, it's advised to use 150mg of the sample. It's best to measure the sample on a jeweler’s scale. If scalp hair isn't accessible, an equivalent volume of body hair may be taken. When we mention head hair, we specify scalp hair exclusively. Body hair indicates all other varieties (facial, axillary, etc.).

Process Overview

The core phases involved in the laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial incorporation of a sample into a lab’s system. This step involves confirming the sample was suitably sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening constitutes an initial fast evaluation for substances of abuse. Though Screening offers an affordable way to dismiss drug intake in most samples, a positive outcome must be corroborated to be valid in court. Any samples testing presumptively positive during Screening need additional confirmation.

In cases where a sample proves presumptively positive in Screening, excess hair is retrieved from the starting sample and prepared for Extraction. During this phase, drugs are extracted from hair at much lower concentrations than other techniques (such as urine or oral fluid), contributing to hair drug monitoring being the most challenging methodology to execute.

Confirmation of any positive screening result takes place via GC/MS, GC/MS/MS, or LC/MS/MS. Throughout, all samples testing presumptive positive undergo washing as warranted before confirmation. The full laboratory procedure, from Accessioning to Confirmation, adheres to the scrutiny of both the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug tests can reveal drug consumption for as long as 90 days, unlike urine tests that have a shorter range of detection.
• Challenging to manipulate: It is particularly difficult to alter a hair drug test, ensuring more precise outcomes.
• Delivers historical insights: It can illustrate a pattern of drug consumption across a timeframe, rather than indicating just recent use.

Limitations:

• Incapable of unveiling immediate usage: Drugs take roughly 5-7 days to be visible in hair.
• Expense: Hair drug tests usually cost more than alternate drug testing methods.
• Result variations: Elements such as hair color and individual differences in hair growth may influence drug metabolite concentration in hair.

Note: While often described as "hair follicle tests," the analysis actually inspects 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.
