Hair Follicle Drug Testing - Meservey, IA

What it is, How it works

Hair testing has gained prominence as a highly effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug presence by encasing biomarkers within the fibers of its growing strand. Samples collected near the scalp offer a detection window of up to around 90 days for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to ship.

A 1.5-inch sample comprising approximately 200 hair strands (about the thickness of a #2 pencil) near the scalp equates to 100mg, which is the optimal quantity for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample on a jeweler’s scale. If scalp hair is unavailable, equivalent body hair may be gathered. When mentioning head hair, it specifically pertains to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The drug test results processing in a lab involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial integration of a sample into a lab's system. This step ensures the sample’s proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes extra data entry not covered by an electronic chain of custody system.

Screening provides a quick initial assessment for drug abuse. Screening serves as a cost-efficient way to dismiss drug use in most samples, but a positive screen must be verified for court admissibility. Samples with presumed positives in Screening require additional confirmation.

If Screening indicates a presumptive positive, more hair is extracted from the primary sample for Extraction. During Extraction, drugs are retrieved from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid), making hair drug testing the most challenging approach.

Confirmation for any positive screen result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as essential. The full lab process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests possess a shorter detection timeframe.
• Cheating resistance: Manipulating a hair drug test is quite challenging, thereby enhancing result accuracy.
• Yields historical insights: It can map a drug usage pattern over time, not merely recent use.

Limitations:

• Unable to detect recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Generally, hair drug tests are pricier than alternative methods.
• Result variability: Factors like hair color and individual hair growth changes can influence drug metabolite concentrations within the hair.

Note: While often labeled as "hair follicle tests", the assessment focuses on analyzing the hair strand rather than 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.
