Hair Follicle Drug Testing - Vinton, LA

What it is, How it works

Hair testing is regarded as a potent instrument for identifying drug and alcohol usage. Hair offers a prolonged timeline by capturing biomarkers within the strands' fibers as they grow. When gathered near the scalp, hair can reveal alcohol and other drugs for a detection period of roughly 3 months. Collection is straightforward, hard to tamper, and simple to transport.

A sample of 1.5 inches, comprising roughly 200 strands of hair (similar to a #2 pencil's diameter), close to the scalp, would yield 100mg of hair, the optimum amount for screenings and confirmations. For EtG, add-ons, and/or assessments beyond 10 panels, 150mg is advised. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair cannot be used, an equivalent amount of body hair can be taken. Referring to head hair implies scalp hair specifically. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result encompasses four core procedures: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary procedure of introducing a sample into a lab's system. This involves affirming the sample's proper sealing and dispatch, assigning a random LAN (Laboratory Accessioning Number), and filling in any additional data not captured by an electronic chain of custody system.

Screening offers a preliminary scan for drugs of abuse. Though it's a cost-efficient means to eliminate drug use in most samples, a positive screening requires confirmation to be court-admissible. Any presumed positive samples during Screening need secondary validation.

Should a sample be deemed presumptive positive during Screening, further hair is extracted from the original specimen and readied for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations than those in other methods (e.g., urine or oral fluid), underscoring why hair drug screening is immensely challenging to execute.

Any positive screening outcomes are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The entire lab process from Accessioning to Confirmation is inspected under the scrutiny of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standard accreditations.

Benefits of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug use up to 90 days, unlike urine testing which has a shorter detection span.
• Resistance to tampering: Manipulating a hair drug test is extremely tough, enhancing the accuracy of results.
• Chronological data: It can depict a pattern of drug consumption over duration, rather than recent usage alone.

Drawbacks:

• Incapable of identifying recent use: Drugs become traceable in hair approximately 5-7 days post-use.
• Costly: Hair drug testing often incurs more expense than other testing techniques.
• Result variations: Factors such as hair color and personal hair growth differences can impact drug metabolite concentration in hair.

Note: Commonly termed as "hair follicle tests", the test assesses the hair strand, not the scalp's hair follicle.

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.
