Hair Follicle Drug Testing - Greenleaf, WI

What it is, How it works

Hair sample testing has become recognized as an effective method for detecting drug and alcohol consumption. Hair retains a long-term record of substances by capturing biomarkers within the hair strand as it grows. When cut near the scalp, it can reveal up to a roughly 3-month detection timeframe for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.

A hair sample measuring 1.5 inches, consisting of about 200 strands (equivalent to the width of a #2 pencil) near the scalp, provides 100mg, which is the optimal quantity for analysis and confirmation. For testing concerning EtG add-ons and/or beyond a 10-panel, 150mg is advised. It's suggested to measure the sample with a jeweler’s scale. If scalp hair is not present, an equivalent amount of body hair may be obtained. By head hair, we mean scalp hair alone, whereas body hair indicates all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial entry of a sample into a laboratory's system. This stage includes ensuring the sample's proper seal and shipment, assigning it a random LAN (Laboratory Accessioning Number), and performing any other data input necessary that's not covered by an electronic chain of custody system.

Screening provides an initial assessment for drug abuse indicators. While it's a cost-effective method to exclude drug usage for most samples, a positive result requires confirmation for it to hold up in legal proceedings. Samples that yield presumptive positive results during Screening need a subsequent confirmation step.

In the event a sample suggests a positive outcome during Screening, additional hair is taken from the original sample for Extraction preparation. Drugs are extracted from hair at significantly reduced concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug testing the most challenging methodology to execute.

Confirmation of any presumptive positive Screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positives undergo a washing process before confirmation, if required. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation criteria.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can reveal drug usage for up to 90 days, while urine tests offer a shorter detection period.
• Difficulty to cheat: Cheating a hair drug test is highly challenging, delivering more reliable results.
• Provides historical data: It presents a pattern of substance use over time, not merely recent consumption.

Limitations:

• Cannot detect recent use: It typically takes 5-7 days for drugs to appear in hair samples.
• Cost: Hair drug tests are usually more costly than other testing techniques.
• Variations in results: Elements such as hair color and individual hair growth differences can impact drug metabolite concentration in hair.

Note: Often termed "hair follicle tests", this examination evaluates 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.
