Hair Follicle Drug Testing - Trowbridge Park, MI

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying alcohol and drug consumption. Hair provides a comprehensive timeline of substance use by sealing biomarkers within the strand's fibers as it grows. When cut near the scalp, it can reflect drug and alcohol presence for up to a 90-day period. Hair is straightforward to collect, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches, comprising around 200 strands (comparable to the thickness of a #2 pencil), gathered closest to the scalp, yields approximately 100mg, which is an ideal quantity for both screening and confirmation. For EtG add-ons and tests exceeding 10 panels, 150mg is preferred. It is advisable to weigh this on a precision scale. If scalp hair isn't available, a proportional quantity of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other varieties (such as facial or axillary hair).

Process Overview

The principal stages in processing a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary input of a specimen into a lab's records, which involves ensuring the specimen's seal and dispatch are intact, assigning it a unique LAN (Laboratory Accessioning Number), and completing any remaining data entry that might not be covered by an electronic custody chain.

Screening offers a preliminary assessment for substances of abuse. Although Screening offers a budget-friendly method to dismiss drug use for many specimens, confirmation of a positive screen is necessary for courtroom acceptance. Samples that test presumptive positive in Screening undergo further confirmation.

If a specimen exhibits presumptive positivity during Screening, additional hair is sourced from the initial sample for the Extraction phase. Here, lower concentration drug extraction occurs, unlike other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.

Recognition of any positive Screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS technology. All presumptive positive specimens are cleansed pre-confirmation as required. The full procedure from Accessioning to Confirmation is evaluated both under the CAP (College of American Pathologists) Hair regulation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug testing can spot drug usage for a maximum of 90 days, compared to the briefer detection time of urine testing.
• Resistance to tampering: Hair drug tests are notably hard to tamper with, enhancing result precision.
• Delivers usage patterns: It can show a historical pattern of drug usage over time rather than just recent intake.

Limitations:

• Inability to detect recent consumption: Drugs only become identifiable in hair after approximately 5-7 days.
• Expense: Typically, hair drug tests incur higher costs than alternative testing methods.
• Variability in results: Factors such as hair pigment and personal hair growth differences can modify drug metabolite levels in hair.

Note: Commonly dubbed "hair follicle tests", the analysis actually pertains to the hair strand itself, 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.
