Hair Follicle Drug Testing - Bowleys Quarters, MD

What it is, How it works

The utilization of hair tests has emerged as an effective approach for identifying drug and alcohol consumption. Hair can encapsulate historical data of alcohol and drug intake by embedding biomarkers within the growing hair strand. If collected near the scalp, hair can reveal a detection timeframe extending up to approximately 90 days for alcohol and drugs. It’s easy to gather, relatively hard to tamper with, and simple to dispatch.

A 1.5-inch sample comprising roughly 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, ideal for screening and confirmation purposes. For EtG, additional tests, and/or tests beyond 10 panels, 150mg of the sample is advisable. It's suggested to weigh the sample on a jeweler’s scale. Should scalp hair be unavailable, a comparable quantity of body hair might be collected. The term head hair specifically refers to scalp hair. Body hair encompasses all other varieties of hair (facial, axillary, etc.).

Process Overview

There are four primary steps in the laboratory handling of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial handling of a sample within a lab's system. This entails confirming the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input absent from an electronic chain of custody system.

Screening involves an initial rapid assessment for drugs of abuse. While Screening is an economical means to discount drug usage on the majority of samples, a positive screening necessitates confirmation for legal admissibility. Any samples presumptively positive in Screening do necessitate auxiliary confirmation.

Should a sample be presumptively positive during the Screening phase, additional hair is withdrawn from the initial specimen for Extraction. Here, drugs are extracted from hair at a far lower concentration compared to other methodologies (e.g., urine or oral fluid), underscoring why hair drug screening is the most challenging methodology to execute.

Confirmation of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed prior to confirmation as required. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Sustained detection span: Hair drug assessments can recognize drug use for up to 90 days, as opposed to urine tests which possess a more limited detection period.
• Hard to falsify: Cheating a hair drug test is notably challenging, thus enhancing result accuracy.
• Offers historical insight: It can display a drug use trend over time, as opposed to merely recent use.

Limitations:

• Unable to detect immediate use: Approximately 5-7 days are needed for drugs to become detectable in hair.
• Expense: Hair drug tests typically bear a higher cost compared to other testing methods.
• Result variations: Elements like hair color and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: Although commonly referred to as "hair follicle tests", the analysis is of 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.
