Hair Follicle Drug Testing - Frenier, LA

What it is, How it works

Hair analysis has emerged as a significant instrument for detecting drug and alcohol consumption. By encapsulating biomarkers within the fibers of a growing hair strand, hair offers an extended history of alcohol and drug use. When collected near the scalp, hair can indicate drug and alcohol use for up to a 3-month duration. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.

A strand sample measuring 1.5 inches with about 200 hairs (similar in thickness to a #2 pencil) close to the scalp yields 100mg of hair, ideal for screening and confirmation. For EtG, add-ons, or tests above 10 panels, a specimen weighing 150mg is advisable. It is recommended to use a jeweler’s scale for weighing. If scalp hair cannot be obtained, a comparable quantity of body hair may be utilized. When referring to head hair, this specifically means scalp hair. Body hair refers to any other hair type (such as facial or axillary).

Process Outline

The primary stages in processing a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab’s system, ensuring the sample is properly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and completing any uninput data that an electronic chain of custody system might not cover.

Screening involves a rapid initial assessment for drugs of abuse. Although Screening can economically eliminate suspicion for most samples, a positive result must be confirmed for legal admissibility. Any samples marked as presumptively positive in Screening require a confirmatory check.

For samples deemed presumptively positive during Screening, additional hair from the original specimen is extracted for further analysis. This stage involves drug extraction from hair at substantially lower concentrations compared to alternative methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute.

Confirmation of positive screening results is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any sample flagged as presumptive positive undergoes washing before confirmation if necessary. The entire laboratory process, encompassing Accessioning to Confirmation, is examined under the CAP (College of American Pathologists) Hair designation and complies with ISO/IEC 17025 accreditation standards.

Benefits of hair drug analysis:

• Extended detection period: Hair drug analysis can trace drug use up to 90 days, unlike urine analysis which identifies recent use with shorter windows.
• Resilience against tampering: Hair drug tests are hard to manipulate, ensuring more reliable results.
• Chronological usage data: It charts drug usage over time, unlike tests that only spot recent consumption.

Drawbacks:

• Inability to identify recent use: It typically takes about 5-7 days before drugs become apparent in hair.
• Expense: Hair tests tend to be pricier compared to other testing techniques.
• Result variability: Aspects like hair color and personal differences in hair growth can influence metabolite concentrations in hair.

Clarification: Despite often being labeled as "hair follicle tests", this test evaluates the hair strand, not the follicle under 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.
