Hair Follicle Drug Testing - Sheldon, IL

What it is, How it works

The analysis of hair samples has emerged as a significant method for identifying drug and alcohol consumption. Hair captures a prolonged timeline of alcohol and other substances, encasing biomarkers within the strands of the growing hair. When taken from near the scalp, hair can reveal up to a roughly 3-month detection period for substances. It is straightforward to collect, challenging to tamper with, and easy to transport.

A sample of 1.5 inches consisting of roughly 200 strands of hair (comparable in size to a #2 pencil) from the scalp will yield 100mg, which is the ideal amount for both screening and confirmation tests. For EtG, add-ons, and/or testing exceeding 10 panels, 150mg of the sample is preferred. We suggest using a jeweler’s scale for weighing. If scalp hair is not available, a similar amount of body hair can be used. When discussing head hair, we mean scalp hair exclusively. Body hair refers to all other hair types (such as facial and axillary).

Process Overview

There are four primary steps involved in the lab processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a sample into a lab’s framework. This step includes checking that the sample was properly sealed and shipped, assigning it a random LAB (Laboratory Accessioning Number), and finalizing any extra data entry absent from an electronic chain of custody system.

Screening is a preliminary swift assessment for drugs of abuse. While cost-effective for ruling out drug use in most samples, a positive screen necessitates confirmation for court admissibility. Samples that are presumptively positive in Screening demand subsequent confirmation.

If a sample is deemed presumptively positive during Screening, more hair is then extracted from the original sample and processed for Extraction. During Extraction, drugs are derived from hair at much lower concentrations than other methods (such as urine or oral fluid), which makes hair drug testing the most complex method to execute.

Confirmation of any positive result from Screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection span.
• Hard to manipulate: Cheating a hair drug test is exceedingly difficult, resulting in more accurate outcomes.
• Historical data provision: It illustrates a user’s drug consumption pattern over time, not just recent use.

Limitations:

• Lack of detection for recent use: A period of 5-7 days is needed for drugs to be identifiable in hair.
• Expense: Hair drug tests are typically costlier compared to other drug testing methods.
• Results variability: Elements such as hair color and individual hair growth differences can influence the drug metabolite concentration in hair.

Note: While commonly referred to as "hair follicle tests", the analysis pertains to the hair strand rather than 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.
