Hair Follicle Drug Testing - Biorka, AK

What it is, How it works

Hair testing is now regarded as an effective method to identify drug and alcohol consumption. Hair offers a comprehensive history of substance use by encapsulating biomarkers within the hair shaft's fiber structure. When collected near the scalp, hair can reveal drug and alcohol usage over a period of up to about 3 months. The collection process for hair is straightforward, somewhat resistant to tampering, and simple to send.

A 1.5-inch segment comprising roughly 200 strands of hair (about the same size as a #2 pencil) near the scalp provides 100mg of hair, an ideal quantity for both screening and validation. For EtG, add-ons, and tests beyond the standard 10 panels, a 150mg sample is suggested. We advise measuring the sample on a jeweler’s scale. If scalp hair isn’t available, a similar amount of body hair can be used. When discussing head hair, we mean only the hair on the scalp. Body hair refers to all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory procedures for processing a drug test result consist of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary processing of a sample into a lab’s system. This step verifies the sample's proper sealing and shipment, assigns it a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.

Screening is a preliminary and rapid assessment for drugs of abuse. Despite being a cost-efficient method to eliminate drug use in most samples, a positive screen necessitates confirmation to be considered valid in legal contexts. Samples that show a positive result in Screening need further confirmation.

If a sample tests positive during Screening, additional hair is taken from the original sample for the Extraction phase. During this stage, substances are retrieved from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluids), which makes hair drug screening one of the most challenging testing methods.

Confirmation of any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS. Any samples initially testing positive are treated to a wash before confirmation, if required. The whole process from Accessioning to Confirmation is examined following the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug screening can identify drug use for up to 90 days, compared to the shorter detection range of urine tests.
• Hard to manipulate: Cheating in hair drug tests is highly challenging, resulting in more reliable outcomes.
• Detailed usage history: It provides a timeline of drug use over an extended period, unlike tests that only detect recent use.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug screenings are typically costlier than other drug testing techniques.
• Result variability: Elements like hair color and personal differences in hair growth can influence drug metabolite concentrations within the hair.

Note: The term "hair follicle tests" is often used inaccurately, as the test examines the hair strand, not the follicle under 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.
