Hair Follicle Drug Testing - Hope, NM

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of substances by embedding biomarkers within the strands. When taken from near the scalp, hair can reveal drug and alcohol use for up to 90 days. The collection process is straightforward, hard to falsify, and easy to transport.

A 1.5-inch section comprising roughly 200 hair strands (about the diameter of a #2 pencil) nearest the scalp can produce 100mg of hair, which is optimal for analysis. For EtG, additional tests, or those exceeding 10 panels, 150mg is advised. It's best to measure the sample on a jeweler’s scale. If scalp hair isn't an option, a comparable volume of body hair can be used. Note that head hair specifically refers to scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The key phases of a laboratory drug test analysis are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial setup of a sample in a laboratory’s database. Steps include ensuring the sample is correctly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any missing data from an electronic chain of custody system.

Screening provides a preliminary evaluation for substances of abuse. While Screening is economically efficient for excluding drug use in most samples, positive results must be verified for legal admissibility. Samples yielding a presumptive positive in Screening necessitate follow-up Confirmation.

If Screening indicates a potential positive, more hair is extracted from the original sample to prepare for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), highlighting the complexity of performing hair drug tests.

Verification of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positives undergo washing prior to confirmation when necessary. The entire lab procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests can reveal drug use for up to 90 days, while urine tests cover a shorter period.
• Difficulty to manipulate: It's challenging to alter hair drug test results, enhancing accuracy.
• Shows usage patterns: Offers insight into drug usage over time rather than just recent intake.

Limitations:

• Cannot detect immediate use: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug testing tends to be costlier compared to other methods.
• Result variations: Elements such as hair color and individual hair growth differences can influence the levels of drug metabolites in hair.

Note: While commonly called "hair follicle tests," the analysis is conducted on the hair strand and not the scalp's hair follicle.

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.
