Hair Follicle Drug Testing - Sun Prairie, WI

What it is, How it works

Hair testing has emerged as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged history of these substances by embedding biomarkers within the fibers of the hair as it grows. When collected adjacent to the scalp, hair can extend up to a 3-month period for recognizing alcohol and drug use. It is straightforward to gather, relatively hard to tamper with, and uncomplicated to transport.

A 1.5-inch segment consisting of around 200 hairs (approximately the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, which is the ideal quantity for both screening and confirmation. For tests like EtG, additional panels, or those exceeding 10 panels, 150mg of the sample is advised. It is recommended to weigh the sample using a jeweler's scale. If scalp hair cannot be obtained, an equivalent quantity of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other types of hair (e.g., facial, axillary).

Process Overview

The procedure for processing a drug test result in the lab consists of four core stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the primary step where a sample is incorporated into a laboratory's system. This step includes verifying that the sample is correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing extra data entry not covered by an electronic chain of custody system.

Screening is a preliminary rapid test for substance abuse. Although it is a cost-saving approach to dismiss drug usage for most samples, a positive screen requires confirmation to be accepted in legal settings. Any sample that returns a presumptive positive during Screening must have a secondary confirmation.

If Screening indicates a presumptive positive, additional hair is extracted from the initial sample for Extraction. In this phase, substances are extracted from hair at a concentration much lower than in other methods (such as urine or oral fluid), making hair drug testing the most complex methodology to execute.

Confirmation of any positive Screening outcome is done via GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples are washed before confirmation when necessary. The complete lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can detect drug consumption for up to 90 days, unlike urine tests which have a shorter detection duration.
• Hard to manipulate: Cheating a hair drug test is extremely difficult, thus enhancing result accuracy.
• Offers historical insight: It provides a pattern of drug usage over time, not merely recent consumption.

Limitations:

• Incapable of identifying recent usage: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug tests are typically pricier compared to other drug testing methods.
• Result variations: Elements like hair color and personal differences in hair growth may impact the drug metabolite levels in hair.

Note: Commonly dubbed as "hair follicle tests", the analysis involves the hair strands, 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.
