Hair Follicle Drug Testing - Shaft, MD

What it is, How it works

Hair analysis has emerged as a robust method for detecting alcohol and drug consumption. The fibers of a growing hair strand capture biomarkers, offering a lengthy history of substance use. Collected near the scalp, hair can provide up to a 3-month timeframe for detecting alcohol and drug use. It is easy to collect, challenging to tamper with, and simple to transport.

A 1.5-inch section of approximately 200 hair strands (roughly the diameter of a #2 pencil) near the scalp yields 100mg, an ideal amount for screening and validation. For EtG, supplementary tests, and/or panels exceeding 10, a 150mg specimen is advisable. We suggest weighing the sample with a jeweler’s scale. If there is no scalp hair, a comparable amount of body hair can be collected. "Head hair" refers specifically to scalp hair. "Body hair" encompasses all other types, such as facial or axillary hair.

Workflow Summary

The key steps in the lab analysis of a drug test sample are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial intake of a sample into a lab's system and includes verifying proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional manual data entry not provided by an electronic chain of custody system.

Screening involves a preliminary quick test for substances of abuse. While screening offers an economical way to exclude drug use for most samples, a positive result requires confirmation before it is legally admissible. All samples with positive screening results must undergo a secondary confirmation.

For samples testing positive in Screening, additional hair is extracted from the original specimen and prepared for Extraction. At this stage, drugs are extracted at a much lower concentration than other methods (e.g., urine or oral fluid), which makes hair drug testing a challenging methodology.

Confirmation of positive screening results is done via GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives are cleaned before confirmation if necessary. The lab process from Accessioning through Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Resistant to deception: Cheating a hair drug test is very difficult, which enhances the accuracy of results.
• Provides usage history: It offers a drug use pattern over time rather than just recent use.

Drawbacks:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests are typically pricier than other drug testing methods.
• Result variations: Factors like hair color and individual hair growth variations can affect the presence of drug metabolites in hair.

Note: Though commonly called "hair follicle tests", the analysis targets the hair strand itself, not 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. 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.
