Hair Follicle Drug Testing - Mammoth Cave, KY

What it is, How it works

Examining hair has emerged as a robust method for detecting drug and alcohol consumption. Hair captures a historical pattern of substance usage by embedding biomarkers within the strands. When taken from near the scalp, hair can reveal alcohol and drug presence spanning up to three months. It is straightforward to gather, resistant to tampering, and convenient to transport.

A specimen measuring 1.5 inches, or 200 strands (comparable to a #2 pencil's diameter), from the scalp supplies 100mg—ideal for both initial screening and subsequent confirmation. For tests such as EtG or those exceeding 10 panels, 150mg is preferred. It's advisable to weigh the sample using a jeweler's scale. If scalp hair is not available, a similar quantity of body hair can be used. By head hair, we mean only the scalp hair. Conversely, body hair includes all other types (facial, axillary, etc.).

Process Overview

For drug test results to be processed in a laboratory, four critical phases exist: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the primary processing of samples into the lab's database happens. This step ensures the sample's integrity, assigns a LAN (Laboratory Accessioning Number), and completes data entry not covered by an electronic chain of custody.

Screening serves as a preliminary drug abuse check. While a cost-efficient method to eliminate drug use in most samples, a positive screen demands confirmation to stand in legal settings. Samples yielding presumptive positives in Screening need subsequent confirmation.

Should Screening indicate a presumptive positive, additional hair from the sample undergoes preparation for Extraction. Here, drugs are isolated from hair at significantly lower concentrations compared to urine or oral fluid methods, which amplifies the complexity of hair drug screening.

Confirmation of any positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples are cleansed prior to necessary confirmations. The entire laboratory workflow, from Accessioning through Confirmation, is scrutinized under both CAP (College of American Pathologists) Hair regulations and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug consumption for as long as 90 days, unlike urine tests, which offer a briefer detection period.
• Hard to manipulate: A hair drug test is challenging to falsify, ensuring reliable results.
• Historical insight: Provides a timeline of drug activity over an extended period, not merely recent use.

Limitations:

• Recent usage detection: Detecting drugs via hair takes roughly 5-7 days post-consumption.
• Expense: Generally, hair drug tests cost more compared to other testing methods.
• Result variability: Variables such as hair pigmentation and individual hair growth patterns can affect drug metabolite levels in hair.

Note: Commonly called "hair follicle tests", these tests evaluate the hair strand itself rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Mammoth Cave, KY, hair follicle tests outshine traditional urine testing. Hair testing offers superior detection accuracy, ensuring drugs are identified well beyond the capacity of urine tests, which are more limited in scope.

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.
