Hair Follicle Drug Testing - Lime, OR

What it is, How it works

Hair testing is regarded as a robust method for identifying drug and alcohol consumption. It offers an extended history of substance use by encasing markers within the fibers of the growing hair. When taken near the scalp, hair can indicate drug and alcohol usage for up to around three months. The collection of hair is straightforward, challenging to tamper with, and convenient to send.

A 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil) near the scalp will yield 100mg, which is an ideal sample for evaluation and verification. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is preferable. Using a jeweler's scale to weigh the specimen is advised. If scalp hair isn’t an option, a comparable portion of body hair may be used. References to head hair imply scalp hair solely, while body hair encompasses other types (facial, axillary, etc.).

Process Overview

The laboratory examination of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage of managing a sample within a lab's framework, including the verification of its proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent in an electronic chain of custody system.

Screening serves as the preliminary rapid assessment for drugs of abuse. Although Screening is cost-efficient for ruling out drug use in most samples, any positive screen must undergo confirmation to be valid in legal settings. Samples that are presumed positive in Screening require further validation.

For samples showing a presumptive positive in the Screening stage, more hair is extracted from the initial sample and processed for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than other methods (like urine or oral fluid), making hair drug screening the most complex method to perform.

The Confirmation of positive screening outcomes is executed with GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are washed before confirmation if necessary. The complete lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Unlike urine tests, hair drug tests can reveal drug use for up to 90 days.
• Challenging to deceive: Cheating a hair drug test is notably difficult, enhancing result accuracy.
• Records past usage: It can illustrate a pattern of substance use over an interval, not just recent consumption.

Limitations:

• Recent use detection: Drugs become noticeable in hair after approximately 5-7 days.
• Expense: Hair drug tests usually incur higher costs compared to alternative techniques.
• Result variability: Hair color and individual differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Commonly called "hair follicle tests," the test examines the hair strand rather than 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.
