Hair Follicle Drug Testing - Sigel, WI

What it is, How it works

Hair testing is now recognized as an effective means for identifying drug and alcohol consumption. Hair can capture biomarkers within the strands as they grow, offering a long-term record of substance use. By collecting hair near the scalp, it's possible to detect drugs and alcohol for about three months. The process of collecting hair is straightforward, it's relatively resistant to tampering, and it's convenient to transport.

A segment of 1.5 inches consisting of around 200 hair strands, akin to a #2 pencil's width, sourced from the scalp, will yield 100mg, which is an optimal sample for testing. For tests like EtG, additional panels, or those exceeding 10, 150mg of hair is advised. The specimen should be measured using a jeweler's scale. If scalp hair isn't available, an equivalent volume of body hair can be collected. Scalp hair refers solely to the head's hair, while body hair pertains to other types of hair (such as facial and axillary hair).

Process Overview

There are four primary steps in processing a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is entered into a lab's system. This process ensures the sample is correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and fills in missing information not included in an electronic chain of custody.

Screening serves as a preliminary rapid assessment for drug abuse. Although Screening is a cost-efficient method to exclude drug usage in most cases, any positive screening must be confirmed for it to be legally valid. Samples that test positive in Screening need a further confirmation.

Should a sample test positive during Screening, additional hair is taken from the original specimen for the Extraction phase. At this stage, drugs are extracted from the hair, although at lower concentrations than in other testing methods (like urine or oral fluid), which makes hair drug testing more challenging.

Any positive result from screening undergoes Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with a presumptive positive result are washed before confirmation as necessary. The entire process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair protocols and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can trace drug use over a span of 90 days, whereas urine tests cover a shorter duration.
• Difficult to adulterate: Cheating on a hair drug test is highly challenging, which enhances result accuracy.
• Shows historical use: It reveals patterns of drug use over time, not just recent consumption.

Limitations:

• Lacks insight into recent usage: Drugs take around 5-7 days to become detectable in hair.
• Expense: Hair drug tests tend to be costlier compared to other testing methods.
• Result fluctuations: Hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Although commonly termed "hair follicle tests", the analysis targets the hair strand and 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.
