Hair Follicle Drug Testing - Commerce, TX

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting substance use related to drugs and alcohol. It retains a comprehensive record of drug and alcohol use by embedding biomarkers within the fibers of the hair as it grows. When hair is taken from near the scalp, it offers a detection span of up to three months for alcohol and drugs. The collection process is straightforward, tampering is challenging, and shipping is convenient.

A sample size of 1.5 inches, consisting of roughly 200 strands of hair (approximately the diameter of a #2 pencil), yields 100mg, which is the optimal amount for testing and confirmation. In cases requiring EtG add-ons or tests beyond 10 panels, a specimen weighing 150mg is advisable. It's suggested to measure the sample on a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be used. The term "head hair" is specific to scalp hair, while "body hair" encompasses all other hair types (such as facial and axillary hair).

Process Overview

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

Accessioning relates to the preliminary processing of a sample within a laboratory’s system, encompassing verification of the sample's proper sealing and shipping, allocation of a random LAN (Laboratory Accessioning Number), and completing any remaining data entry absent from the electronic chain of custody system.

Screening serves as an initial rapid assessment for the presence of drugs. Though a cost-effective measure for eliminating drug use in most samples, confirmed positive tests are essential for legal acceptability. Samples yielding presumptive positives in Screening necessitate further confirmation.

For specimens identified as presumptively positive in Screening, additional hair is extracted from the initial sample and prepped for the Extraction phase. During this stage, drugs are isolated from the hair at considerably low concentrations, in contrast to other methods like urine or saliva testing, underscoring why hair drug screening is notably challenging.

For a confirmed positive result post-screening, technologies such as GC/MS, GC/MS/MS, or LC/MS/MS are employed. Any samples initially testing positive undergo washing before the confirmation stage, as required. The entire laboratory procedure from Accessioning to Confirmation is conducted adhering to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug testing can identify drug usage for as long as 90 days, whereas urine tests offer a briefer detection period.
• Challenging to manipulate: Hair drug tests are difficult to alter, ensuring more reliable results.
• Historical data provision: Supplies a chronological depiction of drug use over time, not merely recent use.

Limitations:

• Limited recent use detection: Drugs require approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests tend to be costlier compared to other drug testing approaches.
• Result variability: Aspects like hair color and individual hair growth rates may influence drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests," the test evaluates the hair strand itself and 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.
