Hair Follicle Drug Testing - New Llano, LA

What it is, How it works

Hair testing is now recognized as a robust method for identifying drug and alcohol consumption. It offers a comprehensive timeline of alcohol and drug use by embedding biomarkers within the hair fibers as they grow. When hair is gathered close to the scalp, it can indicate drug and alcohol presence for up to about three months. Hair collection is straightforward, less prone to tampering, and convenient for transport.

A sample of 1.5 inches consisting of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg, which is optimal for screening and confirmation. For EtG, add-ons, or panels exceeding 10 tests, 150mg is preferable. It's advisable to weigh the hair sample using a jeweler’s scale. If scalp hair isn't accessible, an equivalent amount of body hair can be used. When mentioning head hair, we're specifically referring to scalp hair. Body hair denotes all other types (like facial and axillary hair).

Process Overview

The laboratory process for drug testing includes four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning begins with the sample’s entry into a laboratory's system. This step ensures the sample was sealed and shipped correctly, assigns a random Laboratory Accessioning Number (LAN), and fulfills any necessary data entry absent from an electronic chain of custody system.

Screening performs a swift initial assessment for drug presence. While Screening is a cost-saving measure for negating drug use in most samples, a positive result must be confirmed to hold legal weight. Samples testing presumptively positive during Screening require a follow-up confirmation.

Upon a positive result at the Screening phase, additional hair is retrieved from the primary sample for Extraction. This stage isolates drug compounds from hair at a lower concentration than other techniques like urine or oral fluid testing, which makes hair drug screening notably challenging.

Confirmation of a positive screen employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any samples flagged as presumptively positive are cleansed as necessary before confirmation. An exhaustive review of the laboratory process from Accessioning to Confirmation is conducted under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection timeframe: Hair drug tests uncover drug use up to 90 days, unlike urine tests which have limited detection duration.
• Challenging to manipulate: Cheating with hair drug testing is arduous, thus yielding more precise outcomes.
• Historical analysis: It reveals drug usage trends over time, not just recent activity.

Limitations:

• Inability to detect recent use: Drugs take about 5-7 days to be traceable in hair.
• Expense: Hair drug tests typically incur more costs compared to other drug testing means.
• Result variability: Drug metabolite concentrations in hair can differ due to factors like hair color or individual hair growth variations.

Note: The term "hair follicle tests" is misleading; analysis is performed on the hair strand, not the subcutaneous 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. 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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
