Hair Follicle Drug Testing - Chetek, WI

What it is, How it works

Hair analysis has become recognized as a potent method for identifying drug and alcohol consumption. The fibers of the developing hair strand encapsulate biomarkers, offering a prolonged history of alcohol and substances. When obtained near the scalp, hair can present a detection period of up to around three months for alcohol and other drugs. Hair is straightforward to collect, somewhat challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches composed of about 200 hair strands (approximately the size of a #2 pencil) closest to the scalp yields 100mg, which is the preferred sample size for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advisable. It is recommended to weigh the specimen using a jeweler's scale. If scalp hair isn't accessible, an equivalent volume of body hair can be gathered. References to head hair pertain solely to scalp hair, while body hair references encompass all other forms of hair (facial, axillary, etc.).

Process Overview

The laboratory process for processing a drug test outcome encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary processing of a sample into a lab's system. This step confirms the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not accounted for by an electronic custodial chain system.

Screening is an initial rapid assessment for drugs of abuse. While cost-effective to exclude drug use in most samples, a positive screen requires confirmation for court admissibility. Samples that show presumptive positivity in Screening need a secondary confirmation.

If a sample shows presumptive positivity during the Screening phase, additional hair is extracted from the initial sample for the Extraction phase. In this process, drugs are distilled from the hair at a significantly reduced concentration compared to other methods (e.g., urine or oral fluid), showcasing why hair drug screening is the toughest method to conduct.

Confirmation of a positive screening outcome is performed employing GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are cleansed before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug assessments can identify drug use up to 90 days, unlike urine tests with a more limited detection window.
• Low likelihood of trickery: It is extremely challenging to manipulate a hair drug test, thereby enhancing result accuracy.
• Historical usage insight: It offers a timeline of drug usage, not merely recent consumption.

Limitations:

• Inability to detect recent usage: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug screenings tend to be pricier than alternative drug testing approaches.
• Result variability: Attributes like hair color and personal hair growth differences can influence metabolite concentrations within hair.

Note: Often tagged as "hair follicle tests", the analysis predominantly examines the hair strand, rather than 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.
