Hair Follicle Drug Testing - Litroe, LA

What it is, How it works

The use of hair testing has become recognized as an effective method for identifying drug and alcohol consumption. Hair acts as a long-term record of substance use, capturing biomarkers within the hair strand as it grows. By collecting hair near the scalp, it is possible to obtain a detection period of up to roughly 3 months for alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.

Gathering a 1.5-inch segment of approximately 200 strands of hair (comparable in size to a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal sample for both testing and verification. For tests including EtG, additional panels, or those exceeding 10 panels, a specimen weighing 150mg is advisable. We suggest using a jeweler’s scale to measure the specimen. If scalp hair is not available, an equivalent amount of body hair may be used. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other types of hair (such as facial or axillary hair).

Process Overview

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

Accessioning refers to the initial stage of introducing a sample into a laboratory's system. This process includes ensuring the sample was sealed and transported correctly, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data entry that is not supplied by an electronic chain of custody system.

Screening conducts a preliminary and rapid assessment for substances of abuse. While this approach offers a cost-effective way to dismiss drug use in most cases, any positive findings from Screening must be validated for court admissibility. Samples that show presumptive positivity during Screening require a secondary confirmation.

Should a sample be presumptively positive at the Screening stage, more hair is extracted from the original specimen for preparation in the Extraction stage. During Extraction, drugs are drawn from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which accounts for the heightened complexity of conducting hair drug screenings.

Confirmation of any positive screening outcome is performed through GC/MS, GC/MS/MS or LC/MS/MS techniques. Prior to confirmation, all samples flagged as presumptively positive undergo wash procedures as necessary. The comprehensive laboratory sequence from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair designation and accreditation standards of ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, unlike urine tests with a briefer detection span.
• Challenging to manipulate: The complexity of undermining a hair drug test results in more reliable findings.
• Offers historical insight: This test can reveal a pattern of drug consumption over time, rather than merely recent use.

Limitations:

• Lacks recent use detection: Drugs require about 5-7 days to become traceable in hair.
• Expense: Hair drug tests tend to be pricier compared to other drug testing techniques.
• Result nuances: Variables like hair color and individual differences in hair growth can impact drug metabolite levels in hair.

Note: Although often called "hair follicle tests," the test actually evaluates 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.
