Hair Follicle Drug Testing - Saint Leonard, MD

What it is, How it works

Hair analysis has emerged as an effective technique for identifying drug and alcohol usage. Hair retains a long-term record of these substances by capturing biomarkers within the strands as they grow. When taken near the scalp, hair can reveal a detection period of up to roughly three months for alcohol and drugs. Collection is straightforward, tampering is challenging, and transportation is uncomplicated.

A sample measuring 1.5 inches of around 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp yields 100mg, the ideal quantity for testing and confirmation. For EtG, additional screenings, or panels exceeding ten, 150mg is suggested. It is advised to weigh the hair on a jeweler's scale. If scalp hair is not available, a comparable amount of body hair can be used. Head hair refers exclusively to scalp hair, while body hair includes other types (such as facial and axillary).

Process Overview

The principal steps in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample enters the laboratory system. This involves checking that the sample was correctly sealed and shipped, assigning it a unique LAN (Laboratory Accessioning Number), and completing any missing information not found in an electronic tracking system.

Screening swiftly assesses for substances of abuse. While it's economically viable to exclude drug usage in most samples, a positive finding requires confirmation for legal admissibility. Any presumptive positives in Screening need further validation.

If Screening indicates a presumptive positive, additional hair is taken from the original sample for Extraction. Drugs are isolated from hair at significantly lower levels compared to other methods (such as urine or oral fluid), making hair drug testing one of the most complex processes.

Confirmation of any positive results from Screening is undertaken using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are cleansed before confirmation if necessary. The whole lab process from start to finish complies with both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug analysis can identify drug use up to 90 days, unlike urine tests that offer a shorter timeframe.
• Resistance to deception: Hair drug testing is difficult to manipulate, enhancing result accuracy.
• Historical insights: It reveals usage patterns over time rather than recent consumption.

Limitations:

• Cannot identify recent use: It takes about 5-7 days for substances to be traceable in hair.
• Expense: Hair drug testing tends to be costlier than other methods.
• Result variability: Hair color and individual hair growth rates can influence drug metabolite concentration.

Note: Despite the term "hair follicle tests", the test examines the hair shaft, not the follicle within 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.
