Hair Follicle Drug Testing - Lutak, AK

What it is, How it works

Hair examination is increasingly recognized as a significant method for identifying drug and alcohol consumption. Hair retains a historical record of alcohol and other substances by embedding biomarkers in the fibers of the hair as it grows. When obtained near the scalp, hair can offer an approximately 3-month window for detecting alcohol and other substances. Collecting hair is straightforward, somewhat challenging to tamper with, and convenient to transport.

A 1.5-inch section consisting of roughly 200 strands of hair (approximately the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the preferred amount for assays and verification. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is suggested. Utilizing a jeweler’s scale for weighing the specimen is advised. If scalp hair is absent, an equivalent amount of body hair can be gathered. "Head hair" pertains only to scalp hair, while "body hair" denotes all other hair categories (facial, axillary, etc.).

Process Overview

The four fundamental stages of laboratory testing for a drug analysis result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial incorporation of a sample into a lab’s protocol. This process includes confirming that the sample was properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data input not provided by a digital chain of custody system.

Screening allows for a preliminary assessment for drug misuse. Although Screening is cost-efficient for excluding drug use in most samples, a positive result requires confirmation to be valid in a legal context. Any samples exhibiting presumptive positivity in Screening must undergo secondary verification.

Should a sample show presumptive positivity during the Screening stage, additional hair is extracted from the primary specimen to ready it for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other techniques (such as urine or oral fluid), highlighting why hair drug screening is the most challenging method to execute.

Verification of any positive screening finding is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleansing before confirmation if necessary. The comprehensive lab process from Accessioning to Confirmation undergoes scrutiny according to the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug use for up to 90 days, unlike urine assessments which have a lesser detection duration.
• Resistance to deception: It is notably challenging to deceive a hair drug assessment, thereby enhancing the result's reliability.
• Historical usage data: It offers a pattern of drug consumption over a timeframe, rather than just recent use.

Limitations:

• Lacks detection of recent use: It requires roughly 5-7 days for drugs to be detectable in hair.
• Expense: Hair drug assessments generally incur higher costs compared to other testing methodologies.
• Result variability: Elements such as hair color and personal variations in hair growth can impact drug metabolite concentration in the hair.

Note: Though commonly termed "hair follicle tests," the analysis involves the hair strand itself, 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.
