Hair Follicle Drug Testing - Randle Cliff Beach, MD

What it is, How it works

Hair analysis has emerged as a robust mechanism for identifying drug and alcohol consumption. Hair accumulates a longitudinal record of alcohol and substance exposure by capturing biomarkers within the filament of the growing hair. When procured near the root, hair can yield an approximate 3-month detection timeframe for alcohol and drugs. Hair is straightforward to obtain, comparatively challenging to tamper with, and convenient for transportation.

A segment measuring 1.5 inches, consisting of roughly 200 strands of hair (similar to the width of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the optimal amount for testing and validation. For EtG enhancements and/or evaluations exceeding 10 panels, 150mg of the sample is advised. It’s suggested to weigh the sample using a jeweler’s scale. In the absence of scalp hair, a comparable volume of body hair might be utilized. Head hair refers strictly to scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The four essential phases in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning handles the initial intake of a sample into the laboratory system. This phase includes confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and accomplishing any supplementary data entries not incorporated by an electronic chain of custody system.

Screening serves as a preliminary rapid assessment for substances of abuse. While Screening is an economical method for dismissing drug usage in most samples, a positive result must be verified to be valid in legal contexts. All samples that test presumptively positive in Screening necessitate secondary confirmation.

If a sample tests presumptively positive during the Screening phase, additional hair is extracted from the initial sample for the Extraction phase. In this phase, drugs are isolated from hair at significantly lower concentrations than in alternative approaches (such as urine or oral fluid), which renders hair drug testing the most intricate approach to perform.

Confirmation of any positive Screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if required. The complete lab process, from Accessioning to Confirmation, follows scrutiny under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can reveal drug usage for up to 90 days, whereas urine assessments have a brief detection period.
• Hard to deceive: Attempting to deceive a hair drug test is notably difficult, enhancing result accuracy.
• Supplies historical insight: It can display a trend of drug use over time, beyond just recent consumption.

Limitations:

• Inability to detect recent consumption: It requires about 5-7 days for drugs to become visible in hair.
• Expense: Hair drug tests are typically pricier than alternative drug testing techniques.
• Result disparities: Factors like hair color and personal hair growth differences may impact drug metabolite concentrations in hair.

Note: Even though frequently labeled as "hair follicle tests", the analysis targets the hair strand and 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.
