Hair Follicle Drug Testing - Rayne, LA

What it is, How it works

Hair testing has emerged as a potent resource for identifying drug and alcohol consumption. Hair captures an extended timeline of drug and alcohol presence by embedding biomarkers within the strands of hair as it grows. When obtained near the scalp, hair can offer roughly a 3-month timeframe for detecting drugs and alcohol. Hair collection is straightforward, fairly resistant to tampering, and convenient for shipment.

A sample measuring 1.5 inches with roughly 200 hair strands (comparable to a #2 pencil's size) nearest to the scalp yields around 100mg of hair, which is the optimal quantity for assessment and confirmation. For EtG, supplementary tests, and/or analyses exceeding 10 panels, it's advisable to gather 150mg of the sample. Using a jeweler’s scale is recommended for weighing the specimen. If scalp hair isn't accessible, an equivalent volume of body hair can be collected. When mentioning head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (like facial or axillary hair).

Process Overview

The laboratory processing of a drug test result involves four essential stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the preliminary integration of a sample into the laboratory’s system. This process includes ensuring that the sample was securely sealed and correctly delivered, generating a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry omitted by an electronic chain of custody system.

Screening is an initial rapid assessment for substances of abuse. While Screening efficiently excludes drug usage for numerous samples, a positive screening necessitates confirmation for court admissibility. Any samples identified as presumptively positive during Screening must undergo further confirmation.

When a sample is deemed presumptively positive at the Screening phase, additional hair is separated from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair at far lower concentrations than with other methods (for example, urine or oral fluid), making hair drug screening one of the most challenging methodologies to execute.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with a presumptive positive result are appropriately cleansed before confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which offer a shorter detection duration.
• Difficult to deceive: Cheating a hair drug test is extremely challenging, thereby rendering the results more reliable.
• Supplies historical context: They can illustrate a pattern of drug use over a span of time, beyond merely recent consumption.

Limitations:

• Inability to detect recent use: Detecting drugs in hair takes about 5-7 days following consumption.
• Expense: Hair drug tests usually cost more than other drug testing approaches.
• Result variability: Elements like hair color and personal differences in hair growth rate can alter drug metabolite concentrations in hair.

Note: Often called "hair follicle tests", these tests actually examine 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.
