Hair Follicle Drug Testing - Destrehan, LA

What it is, How it works

Hair analysis is now recognized as an effective means of detecting substance use. It captures a comprehensive history of alcohol and drug exposure by storing biomarkers within the strands of hair as it grows. When sampled near the scalp, hair can offer around a 90-day detection period for both alcohol and drugs. It's straightforward to collect, challenging to tamper with, and simple to transport.

A 1.5-inch section comprising roughly 200 hairs (approximating a #2 pencil's girth) nearest the scalp will yield 100mg, which is optimal for both screening and confirmation. For EtG, additional analytes, or tests exceeding 10 panels, 150mg of hair is advised. Using a jeweler’s scale to weigh the sample is recommended. If head hair is unavailable, a comparable quantity of body hair may be used. References to head hair specifically mean scalp hair. Body hair includes all other types (such as facial, axillary, etc.).

Process Overview

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

Accessioning is the preliminary step of integrating a sample into a lab's system. This step verifies that the sample was correctly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and completes any necessary data entry absent from the electronic chain of custody system.

Screening is an initial assessment for drugs of abuse. Though Screening is an economical method for excluding drug intake in the majority of samples, a positive screen necessitates confirmation to be valid in legal proceedings. Samples with presumed positive results in Screening require additional verification.

If presumptive positives arise in the Screening phase, more hair is taken from the original sample for the Extraction stage. During Extraction, drugs are isolated from hair at lower concentrations than other methods (such as urine or oral fluid), which makes hair drug testing the most complex method to execute.

Confirmation of any positive found in Screening is achieved with GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples suspected as positive are cleansed as required. The entire process, from Accessioning to Confirmation, is subject to review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for as long as 90 days, compared to urine tests with shorter detection times.
• Hard to deceive: The integrity of hair drug tests is difficult to compromise, leading to more precise results.
• Offers usage history: It provides a timeline of drug use over time, not just recent consumption.

Limitations:

• Unable to detect very recent use: Drugs only become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests tend to be costlier than other testing methods.
• Result variability: Elements like hair color and individual growth rates may influence metabolite concentrations in hair.

Note: Referred to as "hair follicle tests", this analysis examines the 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing.
