Hair Follicle Drug Testing - Coulee Dam, WA

What it is, How it works

Hair analysis is recognized as an effective method for detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and drug use by encasing biomarkers within the growing hair fiber. When collected near the scalp, hair can reveal a detection timeframe of up to about 90 days for alcohol and drugs. The collection of hair is easy, not easily tampered with, and straightforward to transport.

A 1.5-inch snippet, consisting of roughly 200 strands of hair (the approximate thickness of a #2 pencil) taken from near the scalp, yields 100mg of hair, which is the optimal sample size for both screening and confirmation. For tests like EtG, additional panels, or those above 10 panels, a 150mg specimen is advised. Measuring the specimen on a jeweler's scale is recommended. If scalp hair is not an option, a comparable amount of body hair might be used. By head hair, we mean scalp hair specifically, whereas body hair includes all other types (such as facial and axillary hair).

Process Overview

The laboratory processing of a drug test result includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a sample into a lab's system, verifying proper seal and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and finishing any extra data entry not covered by an electronic chain of custody system.

Screening serves as an initial rapid assessment for substances of abuse. It's a budget-friendly approach to exclude drug use in the majority of samples; however, a positive screen needs confirmation for legal admissibility. Any screen results that are presumptively positive require further secondary confirmation.

For samples that test presumptively positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. In Extraction, drugs are drawn from hair at significantly lower concentrations than those in other testing methods (e.g., urine or saliva), contributing to the complexity of hair drug testing.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptively positive samples are washed before confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests detect drug use for up to 3 months, unlike urine tests with a shorter detection period.
• Hard to manipulate: Cheating on a hair drug test is exceedingly difficult, enhancing result accuracy.
• Historical insight: It showcases drug use trends over time, beyond recent use alone.

Limitations:

• Cannot trace recent use: A period of roughly 5-7 days is required before drugs become noticeable in hair.
• Expense: Hair drug tests are typically pricier than other testing methods.
• Result variations: Hair color and personal hair growth differences can influence drug metabolite concentration in the hair.

Note: Commonly termed "hair follicle tests", the examination targets the hair strand instead of the scalp-embedded hair follicle.

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.
