Hair Follicle Drug Testing - Garrett, TX

What it is, How it works

Hair analysis has gained recognition as a potent method for identifying drug and alcohol consumption. By embedding biomarkers within the fibers of growing hair strands, hair offers a prolonged account of alcohol and drug presence. When sampled near the scalp, hair provides a detection span of up to three months for alcohol and substances. It's straightforward to gather, challenging to tamper with, and simple to transport.

A hair sample of 1.5 inches consisting of around 200 strands (analogous to a #2 pencil's width) near the scalp produces 100mg, deemed an optimal sample for both screening and validation. For EtG, supplementary, and/or tests exceeding 10 panels, a collection of 150mg is advisable. Utilize a jeweler’s scale to weigh the specimen. If head hair isn’t attainable, an equivalent quantity of body hair can be used. "Head hair" specifically denotes scalp hair. "Body hair" includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test outcome involves four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning embodies the primary processing of a specimen into the lab's system. This phase consists of confirming proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and filling in any absent data not available through an electronic chain of custody system.

Screening entails an initial rapid assessment for substances of abuse. While Screening effectively rules out drug consumption in most samples, a positive screen demands verification for legal admissibility. Samples that are presumptively positive during Screening necessitate further confirmation.

If Screening shows a presumptive positive, additional hair is sourced from the original sample for Extraction. During Extraction, drugs are isolated from hair at notably lower concentrations than other techniques (such as urine or oral fluid), rendering hair drug screening the most intricate technique to execute.

Confirmation of any positive screen results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, every presumptively positive sample undergoes cleansing as required. The entire cycle from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 quality standards.

Advantages of hair drug testing:

• Extensive detection duration: Hair tests can recognize drug use for up to 90 days, surpassing the shorter span of urine tests.
• Tough to manipulate: The difficulty in compromising a hair drug test enhances the accuracy of the results.
• Provides historical insight: Displays a pattern of drug consumption over time, unlike merely indicating recent use.

Limitations:

• Unable to detect immediate use: It generally takes about 5-7 days for drugs to become noticeable in hair.
• Expense: Hair drug assessments typically incur more costs than other testing approaches.
• Result variations: Elements like hair color and personal differences in hair growth can impact drug metabolite concentration within hair.

Note: Commonly termed as "hair follicle tests", the examination actually assesses 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.
