Hair Follicle Drug Testing - Church Point, LA

What it is, How it works

Hair analysis has emerged as a robust method for identifying usage of drugs and alcohol. Hair offers an extended timeline of alcohol and drug consumption by capturing biomarkers within the hair strand's fibers as it grows. When taken near the scalp, hair can represent up to a three-month detection period for both alcohol and drugs. It is straightforward to collect, somewhat resistant to tampering, and convenient to send off.

A segment of hair measuring 1.5 inches from around 200 strands (equivalent to a #2 pencil) drawn from close to the scalp will yield 100mg of hair, which is the optimal amount for both screening and verification. For EtG, additional tests, or tests exceeding 10 panels, a specimen of 150mg is advised. Using a jeweler’s scale for measuring the sample is recommended. In cases where scalp hair cannot be obtained, a comparable amount of body hair will suffice. When we mention head hair, we specifically mean scalp hair only. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result consists of four major steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves bringing a sample into a lab's workflow system. Tasks include confirming that the sample is sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.

Screening is an initial assessment to identify drugs of abuse. Though Screening is cost-efficient in ruling out drug usage in most samples, any positive findings need confirmation for court admissibility. Samples with a presumptive positive in Screening need secondary verification.

If a sample yields a presumptive positive in Screening, additional hair is extracted from the original specimen for the Extraction step. Here, drugs are extracted from hair at far lower concentrations than in alternative methods (e.g., urine or oral fluid), which makes hair drug screening one of the most arduous methodologies.

Positive screening results are validated using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleansed before verification where necessary. The entire process from Accessioning through to Confirmation is conducted under the guidance of the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can note drug consumption over 90 days, unlike urine tests which show shorter detection durations.
• Difficulty with manipulation: Hair drug tests are notably hard to manipulate, resulting in reliable results.
• Shows historical consumption: Provides patterns of drug usage over time, not just recent activities.

Limitations:

• Cannot identify recent consumption: Takes around 5-7 days for drugs to be traceable in hair.
• More expensive: Hair drug tests typically cost more than other testing approaches.
• Variability in results: Elements like hair color and personal differences in hair growth can influence drug metabolite levels in the hair.

Note: Often called "hair follicle tests", the analysis actually pertains to the hair strand, 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.
