Hair Follicle Drug Testing - Congruity, PA

What it is, How it works

Hair analysis has emerged as an effective method for detecting drug and alcohol consumption. Hair captures biomarkers within the strands, offering a historical record of substance use over an extended period. When collected near the scalp, hair can reveal evidence of alcohol and drug use for roughly three months. The process of collecting hair is straightforward, resistant to tampering, and convenient for transportation.

A 1.5-inch section of roughly 200 hairs (approximately the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, which is ideal for testing. For EtG, additional tests, and screenings exceeding 10 panels, a specimen weighing 150mg is advisable. We suggest using a jeweler’s scale for accuracy. If scalp hair is not accessible, a similar quantity of body hair should be obtained. "Head hair" refers exclusively to scalp hair, while "body hair" pertains to other types such as facial and axillary hair.

Process Overview

There are four principal stages involved in processing a drug test result in a lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning represents the preliminary step of entering a sample into the lab system. This step involves confirming the sample's integrity and proper shipment, generating a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not provided by an electronic chain of custody system.

Screening acts as an initial assessment for substances of abuse. Although Screening is an economical means to identify potential substance use in most samples, a positive result must undergo confirmation to be valid for legal purposes. Samples initially testing positive in Screening must be further confirmed.

Should Screening yield a presumptive positive result, additional hair from the original sample is prepared for Extraction. This phase extracts drugs from hair at lower concentrations compared to other testing methods (e.g., urine or saliva), making hair drug screening notably challenging.

Confirmation of a positive Screening outcome is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are thoroughly washed before confirmation as required. The comprehensive laboratory process, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection period: Hair drug tests reveal drug use for up to 90 days, surpassing the shorter timeframe of urine tests.
• Challenging to falsify: Hair drug tests are difficult to manipulate, enhancing result accuracy.
• Historical insight: The tests reveal drug use patterns over time, not merely recent consumption.

Limitations:

• Inability to detect recent use: Drugs typically become detectable in hair 5-7 days post-consumption.
• Expense: Hair drug tests generally incur higher costs than other methods.
• Result variability: Elements like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Although commonly called "hair follicle tests," the analysis focuses on 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.
