Hair Follicle Drug Testing - Martins Additions, MD

What it is, How it works

Hair analysis is increasingly regarded as a robust method for identifying drug and alcohol consumption. The hair captures a long-term record of alcohol and drug intake by embedding biomarkers in its growing fibers. When sampling hair near the scalp, it offers a detection period of up to roughly three months for alcohol and drug presence. The hair collection process is straightforward, relatively resistant to tampering, and simple to transport.

A hair sample of 1.5 inches, consisting of approximately 200 strands (around the thickness of a #2 pencil), yields around 100mg of hair, which is the optimal quantity for both screening and confirmation testing. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg specimen is advised. Utilizing a jeweler’s scale to weigh the sample is suggested. If scalp hair is inaccessible, an equivalent quantity of body hair can be obtained. References to head hair pertain solely to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The lab processing of drug test results involves four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is logged into a laboratory's system. This step includes ensuring the sample is properly sealed and delivered, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data management not provided by an electronic chain of custody system.

Screening is a preliminary assessment to detect drug misuse. While Screening is a cost-efficient method to dismiss drug use in most samples, a positive screen must be validated for it to be legally defensible. Any samples identified as presumptive positive in Screening necessitate follow-up confirmation.

Should a sample test presumptive positive during Screening, more hair is extracted from the initial sample and prepped for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid tests), making hair analysis the most challenging method to execute.

Positive Screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptive positive sample undergoes washing prior to confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is conducted under both the CAP (College of American Pathologists) Hair certification and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug use for up to 90 days, offering a longer detection window than urine tests.
• Challenge to manipulate: It is incredibly challenging to manipulate a hair drug test, resulting in more precise outcomes.
• Provides historical analysis: It indicates an ongoing pattern of drug use over time, rather than just recent consumption.

Limitations:

• Inability to detect recent use: Drugs require around 5-7 days to become detectable in hair.
• Higher cost: Hair drug tests are typically more costly than other drug testing methods.
• Result variability: Factors like hair color and individual hair growth can influence the concentration of drug metabolites in hair.

Note: Though frequently called "hair follicle tests", the analysis actually 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.
