Hair Follicle Drug Testing - Milroy, MN

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. The hair captures long-term evidence of alcohol and drug presence by seizing biomarkers within the fiber structure as the hair grows. When obtained near the scalp, hair can offer an approximate 3-month timeframe of detection for both alcohol and drugs. The collection process is straightforward, though tampering is challenging, and shipment is hassle-free.

A 1.5-inch section containing roughly 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal quantity for testing and verification. For EtG, added tests, and tests exceeding 10 panels, it is advisable to use 150mg of the sample. We suggest measuring the sample with precision on a jeweler's scale. If scalp hair is not available, a similar amount of body hair can be taken. By head hair, we mean scalp hair specifically. Body hair encompasses other types like facial and axillary hair.

Process Overview

The primary steps in the lab processing of drug tests are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the basic entry of a sample into a lab's system, ensuring the sample's proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and completing any additional required data entry that is not captured by an electronic chain of custody system.

Screening is a preliminary rapid assessment for commonly abused drugs. Although Screening is a cost-conscious means of excluding drug use in a majority of samples, a positive screen demands further confirmation for courtroom validity. Samples showing presumptive positives in Screening must undergo additional confirmation.

If a sample yields a presumptive positive in Screening, more hair is extracted from the original specimen for the Extraction process. During this phase, drugs are isolated from hair at a lower concentration than in other methods (e.g., urine or oral fluids), hence hair drug screenings constitute the most challenging methodology.

The confirmation of any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples suggesting positive results are washed before confirmation, as required. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, in contrast to urine tests with shorter periods.
• Resistance to manipulation: It's exceedingly difficult to manipulate hair drug tests, enhancing result reliability.
• Historical insight: It reveals drug usage trends over a duration, extending beyond recent consumption.

Limitations:

• Inability to detect recent use: Drugs take about 5-7 days to become detectable within the hair.
• Expense: Hair drug testing is typically more costly compared to other testing techniques.
• Result variability: Aspects such as hair color and personal hair growth rates can influence drug metabolite concentrations.

Note: While often termed "hair follicle tests", the analysis actually focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Milroy, MN, the advantages of hair follicle testing surpass the traditional urine test. With a longer detection window, hair testing provides more reliable and accurate results.

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.
