Hair Follicle Drug Testing - Lebeau, LA

What it is, How it works

Hair analysis is recognized as an effective means for detecting drug and alcohol consumption. Hair retains a chronological record of alcohol and other substances by capturing biomarkers in the hair strand as it grows. When obtained near the scalp, hair can reveal drug and alcohol use within a roughly 3-month period. Collection of hair is straightforward, relatively tamper-proof, and easy to send.

A 1.5-inch segment containing around 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred amount for analysis and validation. For EtG, add-ons, or panels exceeding 10, a sample of 150mg is advised. It is best to measure the sample using a jeweler’s scale. If scalp hair cannot be used, an equivalent quantity of body hair may be substituted. References to head hair signify only scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test outcome consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is integrated into a lab’s system. This step ensures the sample was packaged and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and includes any extra data entry absent from an electronic chain of custody system.

Screening conducts an initial rapid evaluation for drug use. Although Screening efficiently rules out drug use in most samples, successful legal acceptance requires a positive screen to be validated. Any samples flagged as presumptively positive during Screening necessitate further verification.

If a sample is flagged as presumptively positive in Screening, additional hair is extracted from the initial sample for preparation in the Extraction phase. At this stage, drugs are extracted from hair at significantly lower levels than alternative methods (e.g., urine or oral fluid), which makes hair drug testing a challenging procedure to execute.

Validation of any positive screening results is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive are cleansed before confirmation as needed. The entire lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 criteria.

Benefits of hair drug testing:

• Extended detection range: Hair drug testing can identify drug usage up to 90 days, compared to urine tests, which have a more limited detection period.
• Difficult to manipulate: Cheating on a hair drug test is quite challenging, enhancing the accuracy of results.
• Offers historical perspectives: The test can illustrate a pattern of substance use over time, not just recent usage.

Drawbacks:

• Inability to detect recent usage: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug testing tends to be pricier than other drug evaluation methods.
• Inconsistent outcomes: Variables like hair color and personal differences in hair growth can affect the concentration of drug metabolites in hair.

Note: Despite often being called "hair follicle tests", the analysis pertains to the hair strand 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.
