Hair Follicle Drug Testing - Carney, MD

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair strands encapsulate a prolonged history of alcohol and drug presence by embedding biomarkers within the hair strand’s fibers as it grows. When sampled proximal to the scalp, hair provides a detection span of up to three months for alcohol and drugs. Hair is easy to collect, somewhat resistant to tampering, and straightforward to transport.

A hair sample of 1.5 inches consisting of around 200 strands (approximately the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, which is the ideal amount for screening and confirmation purposes. For EtG testing, extended panels, and/or tests beyond 10 panels, 150mg of specimen is suggested. Utilizing a jeweler’s scale for weighing the specimen is advisable. If scalp hair is not accessible, an equivalent quantity of body hair can be collected. Here, head hair indicates scalp hair alone, whereas body hair pertains to all other varieties (like facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result encompasses four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a specimen within a lab's system. The procedure verifies that the sample has been securely sealed and appropriately transported, assigns a distinct LAN (Laboratory Accessioning Number), and undertakes any leftover data entry not included in an electronic chain of custody system.

Screening signifies the initial swift assessment for detecting substances of abuse. Although Screening is an economical approach for excluding drug usage in most samples, a confirmed result is required for it to be valid in legal settings. Any samples that return a presumptive positive result during Screening necessitate tertiary confirmation.

For samples preliminarily positive in the Screening phase, additional hair is extracted from the initial batch and readied for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid), which contributes to hair drug screening being amongst the most intricate methodologies to execute.

Verification of any positive screening output is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive findings undergo necessary washing prior to confirmation. The comprehensive lab process from Accessioning to Confirmation undergoes review based on both the CAP (College of American Pathologists) Hair designation and conformance to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection window: Hair drug assessments can trace drug use for as long as 90 days, contrasting with urine tests which offer a shorter timeframe.
• Minimized evasion: Cheating on a hair drug evaluation is notably challenging, thus enhancing result authenticity.
• Historical use data: It provides a history of drug use patterns over time, instead of only recent usage.

Limitations:

• Inability to detect recent use: Drugs only become discernible in hair after about 5-7 days.
• Expense: Hair drug examinations tend to be costlier than other drug testing methods.
• Result variability: Aspects like hair color and individual hair growth differences can alter the drug metabolite concentrations in hair.

Note: Commonly termed "hair follicle tests," the analysis targets the hair strand instead of 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.
