Hair Follicle Drug Testing - Flowing Springs, AZ

What it is, How it works

Hair testing has increasingly become a highly effective means for detecting substance use. Hair serves as a long-term indicator of alcohol and drug consumption by embedding biomarkers in the hair strand fibers as they grow. Hair collected near the scalp can reveal drug and alcohol usage for up to around three months. The collection of hair is straightforward, it is relatively resistant to tampering, and it is convenient to transport.

Collecting a 1.5-inch segment from approximately 200 hair strands (equivalent to the width of a #2 pencil) nearest the scalp results in 100mg of hair, the optimal quantity for both screening and confirmation processes. For tests involving EtG, addons, or more than 10 panels, a specimen weighing 150mg is suggested. Use a jeweler’s scale for weighing the specimen. If no scalp hair is available, a comparable amount of body hair is suitable. "Head hair" pertains exclusively to scalp hair whereas "body hair" includes all other types (such as facial or axillary hair).

Process Overview

The laboratory processing of a drug test result includes four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first stage wherein a sample is entered into the laboratory's systems. This entails checking that the sample was appropriately sealed and transported, generating a random LAN (Laboratory Accessioning Number), and performing additional data entry that an electronic chain of custody may not cover.

Screening is a preliminary swift assessment to detect drug abuse. Although Screening is a cost-efficient approach to exclude drug usage in most samples, any positive outcomes in Screening require confirmation for them to be legally valid. Samples showing presumptive positivity in Screening must undergo confirmatory testing.

When a sample tests presumptive positive in the Screening phase, more hair from the initial sample is readied for Extraction. This phase involves drawing drugs from the hair at much lower concentrations than other methods (like urine or saliva), accounting for why hair drug screening is the toughest technique to implement.

Confirmation of any positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples with presumptive positivity undergo washing as necessary before confirmation. The entire procedure from Accessioning through Confirmation is subject to review under the guidelines of the CAP (College of American Pathologists) Hair designation as well as compliance with ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Longer detection duration: Hair drug tests detect drugs for up to 90 days, whereas urine tests have a shorter detection period.
• Difficult to manipulate: Cheating on a hair drug test is extremely difficult, leading to more reliable results.
• Historical consumption patterns: It provides information on drug usage patterns over extended periods, not just recent consumption.

Limitations:

• Cannot detect recent consumption: Drugs become detectable in hair within about 5-7 days.
• Expense: Hair drug tests are typically more costly than other drug screening methods.
• Result variability: Variables like hair color and individual growth rates can influence drug metabolite concentrations in hair.

Note: These tests are known as "hair follicle tests", although they examine 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.
