Hair Follicle Drug Testing - Lafourche, LA

What it is, How it works

Utilizing hair analysis has emerged as an effective approach for identifying drug and alcohol consumption. Hair records prolonged substance history by embedding biomarkers within the hair strand's fibers as it grows. If taken near the scalp, hair can indicate up to roughly a 3-month window for alcohol and drug detection. The collection is straightforward, poses challenges for tampering, and is simple to transport.

A 1.5-inch cutting of around 200 hairs (comparable to a #2 pencil's thickness) from the scalp yields 100mg of hair, ideal for both screening and confirmation. For EtG additions, or tests beyond 10 panels, 150mg of hair is advised. We suggest using a jeweler’s scale for measurement. Should scalp hair be inaccessible, an equivalent portion of body hair is acceptable. Here, head hair relates to scalp hair specifically. Whereas, body hair encompasses other types (facial, axillary, etc.).

Process Overview

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

Accessioning signifies the initial incorporation of a sample into the lab’s framework. This entails ensuring the sample's seal and shipment integrity, allocating a random LAN (Laboratory Accessioning Number), and filling in additional data not covered by an electronic chain of custody system.

Screening entails an initial rapid screening for drugs of abuse. Though cost-efficient for excluding drug usage in most specimens, any positive screening result necessitates confirmation to be viable in judicial settings. Samples testing presumptively positive during Screening require further verification.

Presumptively positive samples in the Screening phase undergo further hair extraction from the original sample for Extraction. This phase involves extracting drugs from hair at a substantially lower concentration than alternative methods (e.g., urine or saliva), explaining why hair drug analysis is the most intricate technique.

Confirmation of any positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples are cleansed before confirmation as necessary. The overarching lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair status and ISO/IEC 17025 accreditation benchmarks.

Advantages of hair drug testing:

• Extended detection window: Hair drug analysis identifies drug use for up to 90 days, surpassing the shorter detection span of urine tests.
• Difficult to deceive: Hair drug tests are highly resistant to manipulation, enhancing result accuracy.
• Delivers historical insights: Offers a pattern of drug consumption over time, not just recent activity.

Limitations:

• Incapable of recent use detection: Drugs become detectable in hair after approximately 5-7 days.
• Price: Hair drug analysis is usually more costly than other testing methods.
• Result variability: Factors including hair color and individual growth rates can influence drug metabolite concentration in hair.

Note: Despite being commonly termed "hair follicle tests", the analysis targets 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
