Hair Follicle Drug Testing - Bancroft, LA

What it is, How it works

A crucial method for detecting drug and alcohol consumption, hair testing is highly regarded in its field. Hair strands, as they grow, embed biomarkers along their fibers, offering a substantial timeline of alcohol and drug history. If samples are obtained near the scalp, hair testing can reveal substance use within a window of up to three months. It's notable for being easy to collect, hard to tamper with, and convenient to transport.

Collecting a sample of 1.5-inches consisting of roughly 200 hair strands, akin to the width of a #2 pencil, close to the scalp will yield approximately 100mg of hair, which is ideal for screening and confirming test results. For higher-capacity panels, such as those including EtG or over 10-panel tests, 150mg of hair is preferred. Utilizing a jeweler's scale for specimen weighing is recommended. Should scalp hair be unavailable, equivalent amounts of body hair can be utilized. When discussing head hair, it exclusively pertains to scalp hair, while body hair encompasses all other types (including facial and axillary hair).

Process Overview

The processing of drug testing in a laboratory includes four primary phases: Accessioning, Screening, Extraction, and Confirmation.

In the Accessioning phase, a sample is initially processed into the lab's system. This step involves checking that the sample was appropriately sealed and shipped, allocating a unique LAN (Laboratory Accessioning Number), and completing any further data entry not managed by an electronic chain of custody system.

During the Screening process, an initial assessment for drugs of abuse is conducted. Screening is an economical approach for ascertaining drug use absence in most samples; however, positive screening results require confirmation to be courtroom-acceptable. Samples that show presumptive positivity in Screening need secondary confirmation.

Should a sample be presumptively positive during the Screening phase, more hair is collected from the initial batch for the Extraction stage. At this juncture, drugs are drawn from hair at concentrations lower than those in other methods, such as urine or oral fluid, making hair drug screening among the most challenging methodologies.

Confirmation of positive screening results utilizes GC/MS, GC/MS/MS, or LC/MS/MS systems. Presumptive positives undergo washing as necessary before confirmation. The entire sequence from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation by ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have the ability to identify drug consumption over a 90-day period, unlike urine tests with shorter detection ranges.
• High resistance to tampering: Cheating a hair drug test is notably challenging, thus ensuring high result precision.
• Historical insight: It offers a timeline of substance use over several weeks, not just recent activities.

Limitations:

• Inability to detect recent usage: Drugs require approximately 5-7 days to become detectable in hair.
• Expense: Hair drug testing tends to be more costly than other testing options.
• Result variation: Hair color and personal hair growth variations can influence drug metabolite concentrations in hair.

Note: This method is commonly mischaracterized as "hair follicle tests", although it specifically analyzes 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.
