Hair Follicle Drug Testing - New Vienna, IA

What it is, How it works

Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. It captures a prolonged history of substance use by ensnaring biomarkers within the fibrous structure of hair strands. When sourced near the scalp, it can extend up to a roughly 3-month timeframe for detecting substances. Hair is straightforward to collect, challenging to tamper with, and convenient for transportation.

A sample measuring 1.5 inches, consisting of about 200 hair strands (comparable to a #2 pencil's thickness) closest to the scalp, yields 100mg, the optimal amount for both preliminary and confirmatory testing. For EtG, additional tests, or analyses surpassing 10 panels, 150mg is the advised quantity. We suggest using a jeweler’s scale for weighing the specimen. In the absence of scalp hair, an equivalent mass of body hair is permissible. 'Head hair' specifically refers to 'scalp hair,' while 'body hair' encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory assessment of a drug test involves four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial integration of a sample into the lab’s system. This involves checking that it was sealed and dispatched correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any non-electronic chain of custody data entry.

Screening offers a preliminary focus on detecting drugs of misuse. Although it is an efficient method to exclude drug use in most samples, a positive screen mandates confirmation for legal validity. Samples that suggest positive results during Screening require subsequent validation.

Should a sample indicate positive Screening results, additional hair from the primary specimen undergoes preparation for Extraction. This phase involves isolating drugs from hair in much smaller concentrations than other methods (such as urine or saliva), adding complexity to hair drug screening.

Any positive screening outcome is confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Samples that preliminarily test positive undergo a washing process prior to confirmation if necessary. From Accessioning to Confirmation, the procedure is conducted under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests identify drug usage up to 90 days, unlike urine tests with a shorter detection period.
• Cheating resistance: Cheating a hair drug test is exceptionally tough, enhancing result precision.
• Offers historical insight: It reveals a drug use trend over a timeline, rather than recent consumption alone.

Limitations:

• Inability to detect immediate use: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug testing tends to be costlier compared to other testing techniques.
• Result variability: Elements like hair color and personal hair growth variations may influence the drug metabolite concentration in the hair.

Note: Commonly termed as "hair follicle tests," the analysis actually examines the hair strand, not 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.
