Hair Follicle Drug Testing - Woodland, MI

What it is, How it works

Hair testing has gained recognition as an effective measure for tracing drug and alcohol consumption. Hair offers an extended timeline of substance use by encapsulating markers within the fibers of the growing strand. When taken near the scalp, hair can deliver up to a 3-month window for detecting alcohol and drugs. Collection is straightforward, tampering is challenging, and shipping is convenient.

A 1.5-inch section of approximately 200 hair strands (comparable to a #2 pencil) nearest the scalp yields 100mg, which is the optimal quantity for screening and validation. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is advised. We suggest using a jeweler's scale for accurate weighing. If scalp hair is inaccessible, a comparable quantity of body hair can be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample within a lab's system. This step involves confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finishing any supplementary data input not covered by an electronic chain of custody.

Screening is an initial swift check for drug presence. While Screening is economical for eliminating drug usage in most samples, a positive result necessitates confirmation for legal acceptability. Any samples with presumptive positives in Screening require subsequent validation.

Should a sample test presumptively positive in the Screening phase, additional hair is extracted from the initial sample for Preparation. This stage extracts drugs at a significantly lower concentration from hair compared to other methods (e.g., urine or saliva), making hair drug testing the most intricate method to execute.

Confirmation of any positive result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed as necessary. The entire laboratory procedure, from Accessioning to Confirmation, is reviewed in accordance with CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection: Hair drug tests identify drug use up to 90 days, unlike urine tests with a limited detection period.
• Fraud resistance: Manipulating hair drug tests is extremely difficult, ensuring more precise results.
• Historical insight: These tests offer a usage pattern over time, not just recent consumption.

Limitations:

• Inability to determine recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests typically incur higher costs compared to other testing methods.
• Result variability: Aspects like hair color and growth variations can impact drug metabolite concentration in hair.

Note: Despite being commonly known as "hair follicle tests", the analysis focuses on the hair strand rather than the hair follicle below 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.
