Hair Follicle Drug Testing - Sweet Home, AR

What it is, How it works

Hair testing is now regarded as a strong method for detecting drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug intake by capturing biomarkers within the fiber of the hair strand as it grows. Collected near the scalp, hair can show a detection window for alcohol and other drugs of up to roughly three months. Hair is easy to collect, not easily tampered with, and simple to transport.

A 1.5-inch section of about 200 hair strands (comparable to a #2 pencil) closest to the scalp provides 100mg of hair, the optimal sample for both screening and confirmation. For EtG, add-ons, and/or tests over 10 panels, a quantity of 150mg is advisable. We suggest using a jeweler's scale for measuring the specimen weight. If scalp hair is not available, an equivalent amount of body hair can be used. When referring to head hair, this indicates only scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial insertion of a sample into a lab system, comprising verifying the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input not provided by an electronic chain of custody system.

Screening entails an initial rapid check for drugs of abuse. Screening serves as a cost-efficient method to exclude drug use for most samples, though a positive screen must be confirmed to be legally admissible. Any samples assumed positive in Screening require a secondary Confirmation.

If a sample is noted as presumptively positive during Screening, additional hair is extracted from the initial sample for Extraction. Here, drugs are extracted from hair at a much lower concentration than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology.

Confirmation of any positive screen result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to Confirmation if necessary. The laboratory process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can monitor drug usage for up to 90 days, compared to the shorter detection period of urine tests.
• Tough to falsify: Falsifying a hair drug test is particularly difficult, enhancing result accuracy.
• Offers historical context: It can map out drug usage patterns over time, not just recent consumption.

Limitations:

• Cannot detect recent usage: Drugs only become detectable in hair after roughly 5-7 days.
• Expense: Hair drug tests generally incur greater costs compared to other drug testing methods.
• Result variability: Factors like hair color and individual hair growth rates can influence the concentration of drug metabolites in hair.

Note: Although often named "hair follicle tests," the actual test examines 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.
