Hair Follicle Drug Testing - Couchwood, LA

What it is, How it works

Hair analysis is regarded as an effective means for identifying substance use, including drugs and alcohol. Hair retains evidence of alcohol and drug usage over time by trapping markers within the fibers of the growing hair shaft. Collected near the scalp, hair can reveal up to a three-month record of substance use. It is easy to collect, challenging to tamper with, and straightforward to send.

A hair section measuring 1.5 inches and comprising approximately 200 strands (roughly the thickness of a #2 pencil) taken from the scalp yields around 100mg, which is the ideal quantity for testing and verification. For EtG, additional tests, or those exceeding 10 panels, a 150mg sample is suggested. Utilizing a jeweler’s scale to weigh the sample is advised. If no scalp hair is available, an equivalent amount of body hair can be used. When mentioning head hair, we mean scalp hair exclusively, whereas body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The process of handling a drug test result in the lab includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the initial input of a sample into the lab's system. This step guarantees the sample's proper sealing and shipment, assigns a random Laboratory Accessioning Number (LAN), and completes any remaining data entry absent in an electronic chain of custody setup.

Screening provides a fast initial assessment to detect potential drug abuse. While it is a cost-efficient method to exclude drug misuse in most cases, any positive outcomes must be confirmed to hold up in legal proceedings. Presumptive positives in Screening necessitate a second confirmation.

In cases of presumptive positives identified during Screening, additional hair is extracted from the initial sample and readied for Extraction. This stage involves isolating drugs from hair at much lower concentrations than other techniques (such as urine or oral fluid), making hair drug testing one of the most complex methods to execute.

Confirmation of positive screening results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing before confirmation as necessary. The full lab process, from Accessioning to Confirmation, is guided by the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can reflect drug consumption for up to 90 days, in contrast to urine tests with shorter detection durations.
• Challenging to manipulate: Cheating on a hair drug test is exceptionally difficult, enhancing result accuracy.
• Provides a usage timeline: It can reveal a pattern of drug use over time, beyond just recent consumption.

Limitations:

• Inability to detect recent consumption: It requires about 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests typically cost more than alternative testing methods.
• Result variability: Factors like hair color and individual growth rates can impact drug metabolite concentrations in hair.

Note: Commonly called "hair follicle tests," the assessment targets 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.
