Hair Follicle Drug Testing - Winsted, MN

What it is, How it works

Hair analysis has emerged as an effective strategy for identifying substance and alcohol consumption. Hair acts as a repository of alcohol and other drugs over an extended period by encasing biomarkers within the strands of hair as they grow. When samples are taken near the scalp, hair can reveal drug and alcohol use over a span of up to about 90 days. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal amount for testing and verification. For EtG, additional analyses, and/or panels beyond ten, a sample of 150mg is advised. Utilizing a jeweler’s scale for measurement is suggested. If no scalp hair is present, an equivalent quantity of body hair may be gathered. References to head hair pertain exclusively to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The key steps involved in the lab processing of a drug testing sample include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary integration of a sample into the lab's records. This process confirms the sample's secure sealing and transport, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any remaining data entry that isn’t covered by an electronic chain of custody protocol.

Screening serves as a preliminary assessment for substances of abuse. Although screening offers a cost-effective approach to exclude drug usage for most samples, results indicating a positive screen must be further confirmed to be valid in legal contexts. Any samples showing presumptive positives in Screening must undergo a secondary confirmation.

Should a sample show a presumptive positive in the Screening phase, additional hair is sourced from the initial sample and processed for Extraction. During this phase, drugs are extracted from hair at much lower concentrations compared to other methods (such as urine or oral fluids), which makes hair drug testing particularly challenging.

Positive screening confirmations are executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleaned before confirmation, if necessary. The complete laboratory procedure from Accessioning through to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair criteria and certified according to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests are capable of identifying drug use over a 90-day span, whereas urine tests have a shorter period of detection.
• Hard to manipulate: It is challenging to evade a hair drug test, thus enhancing result accuracy.
• Offers chronological data: It can provide insight into patterns of drug use over time, not only recent consumption.

Drawbacks:

• Incapable of detecting recent drug use: It typically takes 5 to 7 days for drugs to become traceable in hair samples.
• Price: Hair drug tests tend to be more costly than alternate drug testing approaches.
• Result variations: Elements such as hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Though commonly termed "hair follicle tests", the analysis is performed on the hair shaft, 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.
