Hair Follicle Drug Testing - St. Martin, MN

What it is, How it works

Hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair retains a prolonged history of alcohol and drug intake by preserving biomarkers within the fibers of the developing hair strand. When cut near the scalp, hair can deliver up to a 90-day window for detecting alcohol and drugs. Hair collection is straightforward, comparatively challenging to tamper with, and simple to send.

A sample length of 1.5 inches consisting of roughly 200 hair strands (comparable to the width of a #2 pencil) near the scalp will yield 100mg of hair, the ideal amount for testing and validation. For EtG, add-ons, or assessments exceeding 10 panels, it is advisable to gather 150mg of the sample. It is suggested to measure the sample on a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be collected. When mentioning head hair, it specifically refers to scalp hair. Body hair refers to other types (such as facial, axillary, etc.).

Process Overview

The four central stages involved in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a specimen into a lab’s system. This stage includes confirming the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not provided by an electronic chain of custody system.

Screening comprises a preliminary swift assessment for drug abuse. While Screening offers a budget-friendly method to exclude drug use for most samples, a positive screen must be substantiated to hold up in court. Any samples that appear positive in Screening require further confirmation.

If a sample appears positive during Screening, more hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are drawn from hair at a significantly lower concentration than in other methods (such as urine or oral fluid), which makes hair drug screening one of the more complex methods to execute.

Confirmation of any positive screen result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and under the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for a duration of up to 90 days, whereas urine tests offer a more limited detection period.
• Harder to manipulate: It is particularly challenging to falsify a hair drug test, thus enhancing accuracy.
• Yields historical insight: It can depict drug usage patterns over a span of time, instead of only detecting recent use.

Limitations:

• Unable to detect recent consumption: It requires around 5-7 days for substances to become traceable in hair.
• Expense: Hair drug tests are often costlier than alternative drug testing approaches.
• Variability in results: Aspects like hair color and individual differences in hair growth can influence metabolite concentration in hair.

Note: Commonly known as "hair follicle tests", the assessment actually examines the hair strand itself and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When considering hair follicle versus urine testing, hair tests provide a distinct edge due to their detection breadth and reliability.

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.
