Hair Follicle Drug Testing - Coppock, IA

What it is, How it works

Hair testing has emerged as a potent instrument for detecting drug and alcohol consumption. Hair offers a comprehensive history of alcohol and other drug use by embedding biomarkers within the fibers of the developing hair strand. When gathered close to the scalp, hair can offer up to nearly a 3-month detection period for alcohol and other drugs. Hair is easy to collect, relatively challenging to tamper with, and straightforward to transport.

A 1.5-inch segment consisting of around 200 hair strands (comparable to the size of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimum sample size for screening and verification. For EtG, additional tests, and/or panels surpassing 10, it is advised to use 150mg of the sample. We suggest weighing the sample with a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair may be gathered. When mentioning head hair, it specifically means scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning is the initial stage where a sample is introduced into a laboratory's system. This comprises confirming that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not catered for by an electronic chain of custody system.

Screening entails an initial rapid assessment for drugs of abuse. Although Screening is a cost-effective method to exclude drug use on most samples, a positive screen necessitates confirmation for legal admissibility. Any samples that show presumptive positivity in Screening do require further verification.

If a sample presents as presumptively positive during the Screening phase, additional hair is drawn from the primary specimen and readied for Extraction. In this phase, drugs are drawn out from hair at notably lower concentrations compared to other methodologies (e.g., urine or oral fluid), thereby making hair drug screening the most complex methodology to conduct.

Verification of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing prior to verification as required. The entire laboratory procedure from Accessioning to Verification is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, compared to urine tests which have a shorter detection period.
• Challenging to deceive: It is quite difficult to manipulate a hair drug test, ensuring the results are more precise.
• Offers historical insights: It can depict a pattern of drug usage over time, not merely recent use.

Limitations:

• Inability to detect recent usage: It requires roughly 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests are typically costlier than alternative drug testing methods.
• Differences in results: Elements like hair color and individual discrepancies in hair growth can influence the concentration of drug metabolites in the hair.

Note: Often dubbed as "hair follicle tests", the test examines the hair strand and not the hair 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.
