Hair Follicle Drug Testing - Dix, IL

What it is, How it works

Hair analysis is widely recognized as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of alcohol and drug use by embedding biomarkers within the strands of hair as it grows. When hair is collected closest to the scalp, it can reveal up to a 3-month period of substance use, making it a reliable indicator of drug and alcohol history. Hair samples are easy to gather, challenging to tamper with, and convenient for shipping.

Collecting a 1.5-inch length from approximately 200 hair strands (equivalent to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the perfect amount for both screening and further validation. For tests such as EtG or those exceeding 10 panels, 150mg of the hair sample is best. It's advisable to measure the sample using a jeweler’s scale. If head hair is not obtainable, an equal amount of body hair may be used. When mentioning head hair, it specifically pertains to scalp hair, while body hair includes other types such as facial and axillary.

Process Overview

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

Accessioning is the initial phase where a sample is integrated into a lab's system. This step ensures the sample was properly sealed and shipped, assigns it a Laboratory Accessioning Number (LAN) at random, and completes any missing data entry not addressed by an electronic chain of custody system.

Screening offers an initial quick assessment for substance abuse. While cost-efficient for excluding drug presence in most samples, a positive screen must undergo verification to be legally admissible. Presumptively positive samples necessitate further confirmation.

If a sample tests positive during the Screening phase, additional hair is extracted from the original sample for the Extraction process. This step separates drugs from the hair at much lower concentrations compared to other methods like urine or oral fluid testing, making hair screening a challenging procedure to undertake.

Any positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to final confirmation, samples are also cleansed as required. The entire laboratory process, from Accessioning to Confirmation, is audited under both CAP (College of American Pathologists) standards and accredited by ISO / IEC 17025.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can find evidence of drug use stretching back 90 days, unlike urine tests, which have a narrower detection span.
• Hard to manipulate: Cheating a hair drug test is quite difficult, ensuring more reliable results.
• Chronological insight: Offers a record of drug use over time, not merely recent usage.

Drawbacks:

• Delayed detection: Drugs only become detectable in hair after about 5-7 days.
• Expense: Hair drug tests are costlier compared to other testing methods.
• Result variability: Hair color and growth differences can influence drug metabolite concentrations.

Note: Although often named "hair follicle tests," the analysis focuses on the hair strand itself, 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.
