Hair Follicle Drug Testing - Hazel Dell, WA

What it is, How it works

Hair analysis has emerged as an effective method for detecting drug and alcohol consumption. Hair records a comprehensive history of alcohol and drug use by embedding biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can reveal up to a three-month detection period for alcohol and drugs. Collection is straightforward, tampering with samples is difficult, and they are convenient to transport.

A sample measuring 1.5 inches and consisting of approximately 200 hair strands (roughly the thickness of a #2 pencil) near the scalp provides an ideal 100mg sample size for both screening and confirmation. For EtG, additional tests, and panels beyond 10, a 150mg sample size is preferable. It's advisable to weigh the specimen with a jeweler’s scale. In cases where head hair isn't available, an equivalent quantity of body hair can be collected. 'Head hair' refers specifically to scalp hair, while 'body hair' includes all other types (such as facial or axillary hair).

Process Overview

The laboratory processing of drug test results consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage of integrating a sample into a laboratory’s system. This process involves checking the sample's seal and shipping condition, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by the electronic chain of custody.

Screening provides a preliminary examination for drugs of abuse. While Screening is an economical method for excluding drug use in most samples, a positive result requires confirmation for legal admissibility. Samples with presumptive positive results in Screening necessitate a secondary verification.

In cases of presumptive positive results during Screening, additional hair is extracted from the initial specimen and subjected to Extraction. In this phase, drugs are extracted from hair at concentrations lower than with other methods (such as urine or oral fluid), underscoring the complexity of hair drug screening.

Confirmation of positive Screening results is performed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positive findings are thoroughly washed prior to confirmation as required. The complete process from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation, adhering to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests reveal drug use for up to 90 days, unlike urine tests with shorter detection spans.
• High security against tampering: The difficulty in falsifying hair drug tests results in greater accuracy.
• Historical drug use insight: Hair tests provide data on drug use patterns over time, beyond recent use.

Limitations:

• Inability to detect recent use: Drugs become identifiable in hair only after approximately 5-7 days.
• Higher cost: Hair drug testing is generally more costly compared to alternative methods.
• Result variability: Factors like hair color and individual hair growth differences influence drug metabolite concentration in hair.

Note: Commonly known as "hair follicle tests," this method examines 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.
