Hair Follicle Drug Testing - Princess Anne, MD

What it is, How it works

Hair assays have evolved into an influential means for identifying substance and alcohol usage. Hair captures a retrospective history of alcohol and drug consumption by embedding biomarkers within the fibers of the hair as it lengthens. When clipped near the scalp, hair can offer a detection scope of up to around 90 days for alcohol and drugs. Hair collection is straightforward, moderately hard to tamper with, and convenient for transportation.

A portion measuring 1.5 inches comprising roughly 200 hairs (comparable to a #2 pencil’s girth) nearest to the scalp yields 100mg of hair, which is optimal for both testing and corroboration. For EtG, supplementary checks, and/or examinations exceeding 10 panels, an amount of 150mg is advised. We suggest using a jeweler’s scale to measure the sample. If scalp hair isn’t obtainable, an equivalent quantity of body hair can be used. When we mention head hair, it pertains solely to scalp hair. Body hair encompasses every other type (facial, axillary, etc.).

Process Outline

There are four key stages in processing a lab drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of incorporating a sample into a lab’s system. This step verifies that the sample was correctly sealed and dispatched, assigns a randomized LAN (Laboratory Accessioning Number), and completes any residual data compilation not covered by an electronic custody tracking system.

Screening offers a preliminary rapid assessment for illicit drug utilization. Although screening is a budget-friendly approach to preclude drug usage across most specimens, a positive indication must be validated to be court-admissible. Any samples deemed initially positive during Screening necessitate a subsequent verification.

If a sample shows a preliminary positive during Screening, additional hair from the original collection is then processed for Extraction. This phase involves extracting drugs from hair at notably lower concentrations than other techniques (such as urine or oral fluid), which highlights why hair drug assays are the most complex to execute.

Verification of any positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Each sample with a presumptive positive is cleansed pre-verification as needed. The complete laboratory process, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and the audit to ISO / IEC 17025 protocols.

Benefits of hair drug testing:

• Extended detection period: Hair drug testing can identify drug consumption for as long as 90 days, unlike urine tests which offer a shorter detection range.
• Challenging to falsify: Manipulating a hair drug test is quite difficult, thereby enhancing the reliability of the outcomes.
• Yields chronological data: It can reveal a drug usage pattern across an interval, not merely recent consumption.

Drawbacks:

• Inability to detect recent consumption: A period of roughly 5-7 days is needed before drugs are traceable in hair.
• Expense: Hair drug testing tends to be costlier than other drug testing modalities.
• Result discrepancies: Elements like hair pigmentation and distinct hair growth variations can influence drug metabolite levels within hair.

Note: Although frequently termed "hair follicle tests", the test itself observes the hair strand, not the follicle under the skin.

Why Hair Follicle Testing Beats Urine Testing

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.
