Hair Follicle Drug Testing - Sheshebee, MN

What it is, How it works

Seen as a rigorous method, hair testing effectively identifies drug and alcohol consumption. Hair strands retain a timeline of alcohol and drug use by embedding biomarkers into the hair's fibers. Collected near the scalp, hair offers an extended detection window, around 3 months for substances like alcohol and drugs. Hair samples are straightforward to gather, hard to tamper with, and simple to transport.

A 1.5-inch section comprising roughly 200 hair strands (comparable in size to a #2 pencil) nearest the scalp yields 100mg of hair, optimal for both screening and verification. For EtG, add-ons, and tests exceeding 10 panels, 150mg is suggested. Utilizing a jeweler's scale is advised for specimen weighing. If scalp hair isn't accessible, a corresponding quantity of body hair is acceptable. When discussing head hair, it specifically means scalp hair. Body hair includes other hair types (facial, axillary, etc.).

Process Overview

The laboratory process of deriving a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample first enters the laboratory’s system. This process involves verifying the proper sealing and shipping of the sample, generating a unique LAN (Laboratory Accessioning Number), and completing any supplemental data entry missing from an electronic chain of custody.

Screening entails an initial rapid assessment for potential drug abuse. Screening effectively rules out drug use in most samples economically, but positive screenings require confirmation for legal admissibility. Samples showing presumptive positives in Screening necessitate subsequent verification steps.

If the Screening phase suggests a positive result, additional hair is extracted from the original sample and readied for Extraction. This phase involves isolating drugs from hair at considerably lower concentrations than methods like urine or oral fluid, highlighting why hair drug screening is the most challenging method to execute.

Verification of positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation when needed. The lab's entire process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Hard to falsify results: Cheating a hair drug test is extremely challenging, ensuring more reliable outcomes.
• Historical insight: Offers an overview of drug use over time, not solely recent consumption.

Limitations:

• Misses immediate use: Detecting drugs in hair takes about 5-7 days.
• Higher cost: Generally, hair drug tests incur greater expenses than alternative drug testing techniques.
• Result variability: Elements like hair color and personal hair growth differences can influence drug metabolite concentrations in the hair.

Note: Commonly called "hair follicle tests", the analysis concerns the hair strand itself, not the underlying hair 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.
