Hair Follicle Drug Testing - Howard, WI

What it is, How it works

Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. It captures long-term evidence of substance use by embedding biomarkers in the strands of growing hair. When cut close to the head, hair can offer around a three-month timeframe for detecting drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch section of roughly 200 hairs (comparable to the thickness of a #2 pencil) nearest to the head provides 100mg of hair, the optimal amount for both preliminary and comprehensive testing. For EtG, additional tests, or those exceeding 10 panels, 150mg of hair are advisable. We propose weighing the hair on a precision jeweler’s scale. If hair from the head is not available, an equivalent quantity of body hair can suffice. Head hair specifically refers to hair from the scalp. Body hair encompasses all other types (such as facial, armpits, etc.).

Process Overview

The main procedural steps in lab processing for drug detection are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first stage where the specimen is processed into a lab's database. This step verifies the secure sealing and transportation of the specimen, allocates a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic custody chain system.

Screening is an initial swift test for drug abuse. Such Screening provides an economical means to exclude drug presence in most specimens; however, a positive result must undergo secondary confirmation for legal admissibility. Any presumptive positive findings during Screening necessitate further confirmation.

In cases of presumptive positives from Screening, additional hair is obtained from the primary sample for the Extraction phase. Here, drug quantities are extracted at considerably lower levels than in alternative techniques (e.g., urine or saliva), underlining why hair drug tests present the highest complexity.

Final confirmation of positive screenings is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are cleansed before confirmation. The lab process from Accessioning to Confirmation is reviewed under the CAP's (College of American Pathologists) guidelines and conforms to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair tests can trace drug usage up to 90 days, versus shorter durations with urine tests.
• Tough to manipulate: Hair tests are hard to cheat, ensuring more accurate outcomes.
• Historical tracking: They offer a drug use pattern over time, not merely short-term consumption.

Limitations:

• Not applicable for recent use: It takes roughly 5-7 days for drugs to become recognizable in hair.
• Expense: Hair tests generally cost more than other testing types.
• Result variability: Hair color and personal hair growth variations can influence metabolite concentrations.

Note: Commonly named "hair follicle tests", the assessment actually examines the hair itself rather than the follicle located beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Howard, WI, hair follicle testing surpasses urine testing due to its superior detection accuracy and reliability. Benefits of hair testing include an extended detection window, reducing the likelihood of false negatives for past drug use.

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.
