Hair Follicle Drug Testing - Secretary, MD

What it is, How it works

Hair evaluations have emerged as a robust method for identifying drug and alcohol consumption. Hair acts as a record of prolonged drug and alcohol exposure by capturing biomarkers within the strands of developing hair. Collected near the scalp, hair can indicate drug and alcohol use over a period extending up to roughly three months. It is easy to gather, relatively challenging to tamper with, and straightforward to transport.

A specimen comprising a 1.5-inch segment of about 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp yields 100 mg of hair, which is the optimal quantity for evaluation and verification. In cases of EtG, supplementary assessments, and tests exceeding 10 panels, a 150 mg sample is advisable. Measuring the sample on a jeweler's scale is recommended. If head hair is unavailable, an equivalent quantity of body hair may be used. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other categories (e.g., facial, axillary).

Process Overview

The four principal stages in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial introduction of a sample into a laboratory's system. This entails confirming that the sample was appropriately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any further data entry omitted by an electronic chain of custody system.

Screening consists of a preliminary evaluation for substance abuse. While Screening is an economical approach to eliminate drug use across most samples, validating a positive screen is necessary for court acceptability. Samples presumed positive during Screening necessitate subsequent confirmation.

For samples deemed presumptively positive in the Screening phase, additional hair is extracted from the initial specimen and prepared for Extraction. During this phase, drugs are isolated from hair at a concentration significantly lower than other methods (e.g., urine or oral fluid), making hair drug screening the most complex method to execute.

Verification of any positive screening outcome occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples determined to be presumptive positive undergo washing as needed. The entire laboratory process from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can reveal drug usage over up to 90 days, unlike urine tests that have a shorter detection span.
• Hard to manipulate: Cheating a hair drug test is extremely challenging, leading to more precise results.
• Offers historical insight: Provides a usage pattern over a timeframe rather than just recent use.

Limitations:

• Inability to detect recent usage: It takes about 5-7 days for drugs to become evident in hair analysis.
• Expense: Hair drug tests are typically costlier than other testing techniques.
• Result inconsistency: Elements such as hair color and personal differences in hair growth can impact the concentration of drug metabolites in the hair.

Note: Although commonly called "hair follicle tests," these tests analyze the hair strand and not the scalp-embedded hair follicle.

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.
