Hair Follicle Drug Testing - Marlin, WA

What it is, How it works

Hair testing is now considered a highly effective method for identifying drug and alcohol consumption. Hair captures a long-lasting record of substance use by embedding biomarkers within the hair's fibers as it grows. When taken closely from the scalp, hair can offer an approximate detection period of up to 3 months for substances like alcohol and other drugs. It's straightforward to collect, challenging to tamper with, and simple to transport.

A sample consisting of 1.5 inches of roughly 200 hair strands (comparable in thickness to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the ideal sample size for initial screening and verification. For EtG, additional tests, and/or panels exceeding 10, a recommended 150mg of the sample is required. Using a jeweler’s scale is advised to weigh the sample. If scalp hair cannot be collected, an equivalent mass of body hair is used. "Head hair" refers strictly to scalp hair, while "body hair" encompasses all other varieties (such as facial and axillary hair).

Process Overview

The primary steps in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial handling of a sample into the lab's tracking system. It involves confirming the sample was correctly sealed and dispatched, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data input not already covered by an electronic custody chain.

Screening is the initial swift assessment for drug presence. While it's an efficient way to rule out drug presence in most cases, a positive result in Screening must be confirmed for legal admissibility. Any samples displaying presumptive positive results in Screening require subsequent confirmation.

Should a sample prove presumptive positive at the Screening phase, additional hair is taken from the original sample for Extraction. This stage involves extracting drugs from hair at a lower concentration compared to other methods (such as urine or oral fluids), making hair drug screening particularly challenging.

Confirmation of any presumptive positive screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples testing presumptive positive undergo necessary cleaning before confirmation. The comprehensive lab process, from Accessioning to Confirmation, is reviewed under both CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use for up to 90 days, unlike urine tests that have a shorter detection timeframe.
• High resistance to tampering: Altering results of a hair drug test is very difficult, ensuring greater accuracy.
• Supplies historical patterns: It provides an overview of drug intake patterns over time, not just recent substance use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair only after about 5-7 days.
• Higher costs: Hair drug tests tend to cost more than other testing techniques.
• Result variability: Factors like hair color and individual hair growth differences can influence the levels of drug residues in hair.

Note: Though commonly referred to as "hair follicle tests", these tests evaluate the hair strands and not the follicles 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.
