Hair Follicle Drug Testing - Browerville, MN

What it is, How it works

Hair analysis is increasingly recognized as an effective means for uncovering drug and alcohol consumption. By capturing biomarkers within the strands, hair retains a prolonged account of substance use. When taken near the scalp, hair can reveal a substance history for up to about three months for both alcohol and other drugs. Collection is straightforward, alteration is challenging, and shipment is convenient.

A 1.5-inch strand batch consisting of around 200 hairs (comparable to the thickness of a #2 pencil) close to the scalp yields 100mg of hair, which is the optimal sample size for both screening and confirmation purposes. For EtG tests, additional panels, and tests above ten panels, 150mg is advised. It is advisable to measure the sample using a jeweler’s scale. In the absence of scalp hair, a similar amount of body hair may be gathered. The term head hair specifically pertains to scalp hair, while body hair encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a hair drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating the sample into the laboratory’s system. This phase includes checking that the sample was sealed and dispatched correctly, generating a unique LAN (Laboratory Accessioning Number), and inputting any missing data not included in an electronic chain of custody protocol.

Screening is a preliminary and rapid assessment for substance abuse. While Screening offers a cost-efficient method to discount drug use in most specimens, a positive result must undergo confirmation to hold legal weight. Samples yielding a presumptive positive need a subsequent confirmation.

In cases where Screening results in a presumptively positive outcome, additional hair from the original sample is used for Extraction. During Extraction, drugs are isolated from hair at much lower concentrations than with other methods (such as urine or oral fluids), making hair drug analysis one of the most intricate methodologies to execute.

Any positive Screening result undergoes Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. As required, all samples with presumptive positive results are cleaned prior to Confirmation. The full lab procedure from Accessioning to Confirmation adheres to evaluation under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Benefits of hair drug screening:

• Extended detection period: Hair drug screenings can discover substance use for up to 90 days, whereas urine tests have a shorter detection span.
• Difficulty to manipulate: It is particularly hard to manipulate a hair drug screen, ensuring more reliable results.
• Provides usage trends: It can illustrate a timeline of drug use, rather than just recent consumption.

Drawbacks:

• Inability to identify recent use: Drugs typically become detectable in hair approximately 5-7 days post-usage.
• Higher expenses: Hair drug screenings generally incur higher costs compared to other testing approaches.
• Variance in results: Elements like hair color and personal differences in hair growth can influence the concentration of drug metabolites in the sample.

Note: Despite often being called "hair follicle tests", the analysis itself is performed on the hair strand, not on the follicular structure 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.
