Hair Follicle Drug Testing - St. Marys Point, MN

What it is, How it works

Hair analysis is recognized as an effective technique for identifying drug and alcohol consumption. Hair's ability to capture biomarkers within its fibers offers a long-term record of substance use as it grows. When collected near the scalp, it provides up to a 3-month detection window for drugs and alcohol. Hair collection is straightforward, hard to tamper with, and simple to transport.

A 1.5-inch section comprising roughly 200 hairs, akin to the thickness of a #2 pencil, cut close to the scalp, yields about 100mg, which is optimal for screening and subsequent confirmation. For EtG, additional tests, or panels exceeding 10 drugs, 150mg is advisable. We suggest using a jeweler’s scale to measure the specimen. If scalp hair is absent, a comparable quantity of body hair can be obtained. By head hair, we mean scalp hair. Body hair encompasses other types like facial and axillary hair.

Process Overview

The four critical stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample in a lab’s system, involving verification that the package was securely sealed and correctly shipped, allocating a random LAN (Laboratory Accessioning Number), and finalizing any outstanding data entry not covered by an electronic chain of custody system.

Screening involves a preliminary assessment for substances of abuse. Though an economical method to assess most samples for absence of drugs, any positive screen result must be confirmed for legal acceptability. Those samples with initial positive results in Screening require a secondary validation.

In the event of a presumptive positive from Screening, additional hair is extracted from the original sample and readied for Extraction. Here, drugs are drawn from hair at much lower levels than other techniques (e.g., urine or saliva), highlighting the complexity of performing hair drug analysis.

Further validation of any positive screening outcomes is conducted using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples with presumptive positives are cleaned before confirmation as requisite. The complete lab workflow from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair protocol and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug assessments can identify drug usage for up to 90 days, unlike urine tests which offer a narrower detection timeframe.
• Resistance to tampering: It's notably challenging to manipulate a hair drug test, ensuring result reliability.
• Provides usage patterns: It reveals patterns over time rather than just recent consumption.

Limitations:

• Cannot identify recent use: It typically takes 5-7 days for substances to be traceable in hair.
• Expense: Hair drug testing generally incurs higher costs than alternative methodologies.
• Result variability: Hair color and individual growth variations can influence drug metabolite concentration levels.

Note: Commonly referred to as "hair follicle tests", this methodology actually analyzes the hair shaft, not the follicle beneath the skin.

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.
