Hair Follicle Drug Testing - Cloverly, MD

What it is, How it works

The use of hair analysis has emerged as an effective method for detecting drug and alcohol consumption. Hair is capable of offering a comprehensive history of alcohol and other drug usage by encapsulating biomarkers within the strands as they grow. When sampled near the scalp, it can offer an alcohol and drug detection timeframe of up to roughly three months. Hair collection is straightforward, resistant to adulteration, and convenient to transport.

Obtaining a 1.5-inch segment of roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg of hair, deemed the optimal sample for screenings and confirmations. For EtG, additional testing, or tests exceeding 10 panels, a specimen quantity of 150mg is advised. It is suggested to use a jeweler’s scale for specimen weighing. Should scalp hair be unavailable, an equivalent amount of body hair may be used. References to head hair strictly pertain to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial stage of integrating a sample into a laboratory’s system. This step involves ensuring the sample was sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry that an electronic chain of custody system may not furnish.

Screening consists of an initial rapid assessment for substances of abuse. Although Screening is a cost-efficient method to eliminate drug use for most samples, a positive screen necessitates confirmation to be valid in legal contexts. Any samples preliminarily testing positive during Screening require a follow-up confirmation.

Should a sample present as presumptively positive at the Screening phase, additional hair is extracted from the original specimen and prepared for the Extraction stage. At this phase, drugs are isolated from hair at a significantly lower concentration compared to other techniques (e.g., urine or oral fluid), which is why hair drug testing is considered the most complex methodology to execute.

Verification of a positive Screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation as necessary. The complete laboratory examination process from Accessioning to Confirmation undergoes review in compliance with both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests are capable of identifying drug usage for up to 90 days, in contrast to urine tests which offer a narrower detection range.
• Resistance to manipulation: Cheating a hair drug test is notably challenging, enhancing the accuracy of the outcomes.
• Provides usage pattern: This method reveals a history of drug use over a duration, not merely recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs take about 5-7 days before they become traceable in hair.
• Expense: Hair tests tend to be pricier than alternative drug testing techniques.
• Result variabilities: Aspects like hair color and personal differences in hair growth can influence the concentration of drug metabolites present in the hair.

Note: Although often named "hair follicle tests", the analysis actually examines the hair strand, excluding 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.
